Laboratory Supplement J. Ellen Lathrop-Davis, M.S., Course Coordinator Ewa Gorski, Ph.D. Stephen Kabrhel, M.S., ATC. BIOL 221 A&P II BIOLOGY 221 ANATOMY & PHYSIOLOGY II Laboratory Supplement Welcome to Biology 221 – Anatomy and Physiology II. Like the Biology 220 Laboratory, these exercises are designed to give you experience in: following directions accurately; using microscopes properly and observing histological specimens using prepared slides; identifying anatomical structures based on diagrams, models, and preserved specimens; understanding various physiological processes through experiments and virtual experiments (PhysioEx). You should come to each laboratory prepared to learn. Models, slides, atlases, books, diagrams, etc. may not be taken out of the laboratory. No open lab time is available. Use your time in lab wisely. Read through the upcoming laboratory exercise before coming to lab (see course lab schedule) and write out definitions and functions of structures to be observed. You should bring the following to each lab period: Marieb laboratory manual with PhysioEx CD (all page, figure and table numbers are based on the 8th edition, cat version); 3-ring binder with laboratory supplement, which provides the objectives for the day’s lab activities; paper to take notes; and pencils (preferred) or pens. You are expected to have successfully completed Biology 220 – Anatomy and Physiology I, or the equivalent. We will not review the material covered in that course. You are responsible for material covered in A&P I such as body cavity names, regional terminology, histology, and bones and muscles related to the systems you will study in A&P II. If you had difficulty with any of the subjects, you should review the relevant exercises in the laboratory manual. Lathrop-Davis/ Gorski / Kabrhel BIOL 221 A&P II The laboratory is a place of serious observation and study. Toward that end, please observe the following: 1. Students should maintain appropriate classroom behavior (see the College Catalogue under Student Code of Conduct); disruptive students will be asked to leave the laboratory. 2. Smoking, eating and drinking are NOT permitted in the laboratory at any time. 3. For your safety, close-toed shoes are required in lab. If you are wearing sandals, your instructor may not permit you to enter the lab. It is your responsibility to dress appropriately and wear proper footwear. 4. You may wish to bring a smock to lab when doing dissections. 5. Cell phones and pagers are disruptive – especially during tests. Please turn them to a silent mode; or, better yet, turn them off. In an emergency, you can be reached through the Department Secretary (410-455-4212) or Security (410-455-4545). 6. Models, slides, atlases, books, diagrams, etc. may not be taken out of the laboratory. No open lab time is available. Use your time in lab wisely. Read through the upcoming laboratory exercise before coming to lab (see course lab schedule) and write out definitions and functions of structures to be observed. A limited number of models are available for study in the library. Many excellent web sites exist that provide images of materials similar to those we use in lab. See your instructor for more information. 7. Please treat all materials with care; many students need to use them. Please do NOT use pens, pencils or markers on the models. Probes or pipe cleaners will be available for pointing at structures on models. Report any problems with equipment to the instructor as soon as possible. 8. Clean all equipment used and return it to its place of storage before you leave the lab. Clean up any chemicals that may have spilled during physiological experiments. 9. Dissection is a vital part of understanding anatomical relationships and tissues. Students are expected to participate in dissection of selected materials or view prosections during lab. Dissected materials will appear on most laboratory practical exams; students who do not dissect or observe can expect to lose points on lab exams. Students who object to the use of Lathrop-Davis/ Gorski / Kabrhel BIOL 221 A&P II animal material for dissection must submit a written explanation of their objections by the end of the first full week of classes. Students with valid reasons (“I just don’t want to.” is not a valid reason) will meet with the course coordinator during the first two weeks of class to discuss their objections. 10. Clean up all material used to dissect and dispose of animal parts properly; DO NOT through animal parts in the regular trash. 11. After completing each lab, the student should be able to identify any structure or organ viewed as part of the objectives from models, slides, micrographs and/or diagrams, as appropriate; discuss the function of these structures or organs; and/or discuss physiological principles studied. Review Sheets for each exercise are found at the back of the lab manual. A histology atlas is also located toward the back of the lab book and as part of the PhysioEx CD. You may find these helpful in studying. YOU are responsible for making sure you cover and understand all of the objectives. 12. Group study both during and after lab is highly beneficial. Taking turns “teaching” each other about the material will help both the “teacher” and the “learner” better understand and remember the material. 13. Your instructors are here to help you learn. It is YOUR responsibility to seek help when needed in and out of lab. 14. You are responsible for knowing the importance and/or function of every structure or term listed regardless of whether it is stated in the objective. 15. Attendance is required. If you are going to miss a lab, please contact the instructor as soon as possible, preferably before the missed lab, to schedule a make-up. It is YOUR responsibility to contact the instructor and to make up the material. If your regular instructor does not teach the lab section you want to attend to make up the lab, you must contact that instructor as well to make sure there is room in her/his lab section. Good luck and have a great semester!

Instructor’s Option Lathrop-Davis/ Gorski / Kabrhel Cardiac Physiology BIOL 221 A&P II Experiment: Electrocardiogram and Heart Sounds Overview The cardiac cycle involves a sequential contraction of the atria and the ventricles. The combined electrical activity of the different myocardial cells produces electrical currents that spread through the body fluids. These currents are large and can be detected by recording electrodes placed on the skin. In this lab you will attach three electrodes to a student volunteer. These electrodes will be connected to the iWorx/204 and the signal will be displayed on the computer screen in a strip chart format. The regular pattern of "peaks" produced by each heart beat cycle is called the electrocardiogram or ECG (See Figure 2-1). Figure 2-1: ECG trace in the Main window with labels showing the P, QRS and T waves. The cursors are positioned to measure the amplitude (value in Volts) of the QRS wave. The action potentials recorded from atrial and ventricle fibers are different from those of nerves and skeletal muscle. The cardiac action potential is composed of three phases - a rapid depolarization, a plateau depolarization (which is pronounced in ventricular fibers) and a repolarization back to resting membrane potential. The components of the ECG can be correlated with the electrical activity of the atrial and ventricle fibers such that: the P-wave is produced by atrial depolarization; the QRS complex is produced by ventricular depolarization (atrial repolarization is hidden by the changes due to ventricular depolarization); the T-wave is produced by ventricle repolarization. In this lab you will record ECGs from volunteers at rest, while holding their breath, and following exercise. Lathrop-Davis/ Gorski / Kabrhel Cardiac Physiology BIOL 221 A&P II Equipment Required PC computer iWorx/204 and serial cable AMI cable and three ECG leads (electrode cables) Disposable electrodes Alcohol swabs or wipes Equipment Setup 1. Make sure the iWorx/204 unit is connected to the computer. Ask your instructor for help if it is not. 2. Volunteers should remove all jewelry including watches from their wrists and ankles. 3. Use an alcohol swab/wipe to clean and abrade a region of each wrist that has little or no hair and from an area around the left ankle. 4. Select three (3) disposable electrodes. Remove the plastic sheet covering the adhesive from a disposable electrode and apply the electrode to the abraded area on one wrist. Repeat for the other wrist and the left ankle. 5. Attach the gray AMI connector on one end of the cable to the channel one and two input on the iWorx/204 unit. (See Fig. 2-2.) 6. Examine the lead pedestal of AMI connector and note that it has five (5) ports (openings) into which leads can be placed. Turn the pedestal so that the side with the arrows is facing you. The middle port is for the ground. To the left of the ground are the 1- and 1+ ports, respectively. To the right are the channel 2- and 2+ ports. (See Figure 2-2.) Figure 2-2: The equipment used to measure the ECG from a volunteer. Lathrop-Davis/ Gorski / Kabrhel Cardiac Physiology BIOL 221 A&P II 7. Select three (3) leads. Attach the end of the brown electrode cable to the ground (middle opening). Attach the red and black electrode cables to the channel two inputs (two openings on the left) on the lead pedestal; the black lead should be attached to the end (2+) and the red between the brown and black leads. Snap the other ends onto the disposable electrodes, so that: the "2 -" lead (red) is attached to the right wrist, the "2 +" lead (black) is connected to the left wrist, the ground, or reference, lead (brown) is connected to the left leg. 8. Make sure that ECG is the selected mode; a red light will appear by ECG on the iWorx/204 box. If it is not selected, use the mode control button to select ECG. 9. The volunteer should sit quietly with his/her hands in his/her lap; the hands should not be touching. Start the Software 1. Click LabScribe icon on the desktop if it has not been opened for you. You can also access the program by moving the mouse to Programs (from the Start menu) and then to the iWorx folder and selecting LabScribe. 2. When the program opens, select Heart #1 under Settings. If Heart #1 is not an option, select Load (under Settings); choose HK204 from the menu and click OK; return to Settings and select Heart #1. 3. After a short time the three Heart #1 channels will appear. Channel 1 (top) will be minimized. If it is not, click and hold the top red arrow on the right of the screen and drag it upward. The remaining two channels are for ECG and Sound. The Sound channel will not be used in the present exercises; minimize this window by dragging the lower red arrow to the bottom of the screen. Exercise 1: ECG in Resting Volunteers Aim: To measure the ECG in resting individuals and to view the 3 main waves of the ECG. Procedure 1. Click Start (upper right) and then click AutoScale in the ECG title area. A rhythmic ECG signal (See Figure 2-1) should appear. If the trace is upside down (main peak of the QRS goes down) click Stop and switch the positive (black; 2+) and negative (red; 2-) electrodes. If the signal is too small, the electrodes should be moved from the wrists to the skin immediately below each clavicle. 2. The volunteer should open and close his/her fists, or move his/her arms across their chest. Notice that the trace moves around the screen and the ECG is Lathrop-Davis/ Gorski / Kabrhel Cardiac Physiology BIOL 221 A&P II distorted. This demonstrates that it is necessary to keep still and relaxed when recording the ECG. The electrodes are very sensitive to electrical activity in the muscles as well as in the heart so you may experience a lot of “noise” (added peaks on the screen). If this happens, have the volunteer move their arms into a position that minimizes the excess noise. 3. When you have a suitable trace, type "***'s resting ECG" (where *** is the volunteer's name) in the space next to Mark. Press Enter on the keyboard to enter the mark. 4. After 15 to 20 seconds, click Stop to halt recording -- your data should have a series of peaks (waves) and look similar to Figure 2-1. Figure 2-1: ECG trace in the Main window with labels showing the P, QRS and T waves. The cursors are positioned to measure the amplitude (value in Volts) of the QRS wave Data Analysis 1. Click the 2-cursor icon (See Figure 2-3) so that two blue vertical lines appear over the recording window. Figure 2-3: The LabScribe toolbar 2. Locate a region of the screen containing four good heart beat cycles. Use the mouse to drag the cursors left and right so that the four complete heart beat cycles are located between the two blue lines. (The left cursor should be slightly to the left of the P wave of the first heartbeat; the right cursor slightly to the right of the T wave of the fourth heart beat.) Lathrop-Davis/ Gorski / Kabrhel Cardiac Physiology BIOL 221 A&P II 3. Click the Analysis icon to open the Analysis window. 4. Under Display Channels in the Analysis window (Figure 2-4), click Channel one and Sounds to de-select them and display only the ECG trace. 5. Use the mouse to click and drag the cursors around the Analysis window to: a. measure the time interval (in seconds/beat) between four adjacent QRS waves (you should have three values). The trace can be scrolled horizontally using the arrows in the lower margin. Position the left cursor at the peak of the first QRS wave; position right cursor at the peak of the adjacent QRS wave (Figure 2-4). The time interval (in seconds) will appear as T2-T1. Record your data on the sheet provided. To measure the next time interval, move the left cursor to the right past the other cursor to the top of the next QRS peak. The time interval between these two peaks will now appear as T2-T1. Record this interval on the sheet provided. Repeat the procedure to measure the time interval between two more peaks. You may need to scroll to the right using the scroll bar at the bottom of the screen. Figure 2-4: ECG trace in the Analysis window showing how to use the two cursors to measure the time interval between adjacent QRS waves - in this example the value (T2-T1) is 0.82 s. b. measure the amplitude (in volts) of three QRS waves. Position the left cursor at a suitable low point between the first P and QRS waves; position the right cursor at the peak of the QRS wave. The amplitude (in volts) will appear as V2V1. Record your data on the sheet provided. Repeat for two successive QRS waves. ....................................................Instructor’s Option Lathrop-Davis/ Gorski / Kabrhel Cardiac Physiology BIOL 221 A&P II c. measure the amplitude of three P waves. Position the left cursor at a suitable low point between the T and P waves; position the right cursor at the peak of the P wave. The amplitude (in volts) will appear as V2-V1. Record your data on the sheet provided. Repeat for two successive P waves. ....... Instructor’s Option d. measure the amplitude of three T waves. Position the left cursor at a suitable low point between the QRS and T waves; position the right cursor at the peak of the T wave. The amplitude (in volts) will appear as V2-V1. Record your data on the sheet provided. Repeat for two successive T waves. Instructor’s Option 6. Calculate (and record on your data sheets): a. the average time interval (seconds/beat) between adjacent QRS waves by adding the 3 values and dividing by 3; b. the heart rate in beats per minute by dividing 60 by the time interval: Heart rate = (60 seconds/minute) / (seconds/beat) = beats/min.; and c. the average value for the amplitude of the P wave, the QRS wave and the T wave ....................................................................................................... Instructor’s Option Exercise 2: ECG Recordings During Breath Holding. Aim: To measure heart rate during breath holding. Procedure 1. Start a new tracing for the first volunteer by clicking Start. Record the resting ECG for 10 seconds, or until the ECG is stable. When you have a suitable trace, type "***'s breath-holding ECG" (where *** is the volunteer's name) in the space next to Mark. Have the volunteer begin to hold his/her breath and press Enter on the keyboard to enter the mark. 2. Have the volunteer hold his/her breath for 20 seconds. Just prior to letting out the breath, type “end” in the space next to Mark. Press enter when the volunteer lets out the breath. Click Stop to halt the recording. Perform the data analysis by making measurements of QRS wave amplitude (instructor’s option) and interval between QRS waves as before. Data Analysis Make measurements of QRS wave amplitude (instructor’s option) and interval between QRS waves as outlined above. Calculate heart rate as before. Lathrop-Davis/ Gorski / Kabrhel Cardiac Physiology BIOL 221 A&P II Exercise 3: ECG Recordings Following Exercise Aim: To measure heart rate following exercise. Procedure 1. Disconnect the cables from the electrodes attached to the volunteer’s wrists and ankles. Have the volunteer jog in place for three (3) minutes so that heart rate and ventilation increase. 2. While the student is jogging in place, type "***'s post-exercise ECG" (where *** is the volunteer's name) in the space next to Mark. 3. Immediately after the three (3) minutes of jogging are completed, have the student sit. Reconnect the cables and begin to record the ECGs. 4. Start the tracing by clicking Start. Have the student stay as still as possible to minimize noise from muscle activity. 5. Click Stop to halt recording after 15 to 20 seconds. Data Analysis Make measurements of QRS wave amplitude (instructor’s option) and interval between QRS waves as outlined above. Calculate heart rate as before. Exercise 4: ECG Recordings from Other Students Aim: To compare resting, breath-holding and post-exercise heart rates from two other students. Procedure 1. Disconnect the leads from the first volunteer's wrists and ankle and place them on a second student. Record their ECG as before for resting, breath holding and after exercise. Data Analysis Make measurements and calculate heart rate as done previously.
