IB Sports, Exercise and Health Science Topic One: Anatomy 1.1.1 Distinguish anatomically between the axial and appendicular skeleton. Humans are vertebrates, animals having a vertebral column or backbone. They rely on a sturdy internal frame that is centered on a prominent spine. The human skeletal system consists of bones, cartilage, ligaments and tendons and accounts for about 20 percent of the body weight. Bones provide a rigid framework, known as the skeleton, that support and protect the soft organs of the body. (SEER) The Axial Skeleton outline the axial skeleton in red on the right, label four major bones of the axial skeleton on the right, annotate the general function of the axial skeleton The Appendicular Skeleton outline the appendicular skeleton in yellow on the left, label four major bones of the appendicular skeleton on the left, annotate the general function of the appendicular skeleton See… http://training.seer.cancer.gov/anatomy/skeletal/divisions/ http://www.innerbody.com/image/skelfov.html IB Sports, Exercise and Health Science 1.1.2 Topic One: Anatomy Distinguish between the axial and appendicular skeleton – note how the systems differ in function. AXIAL FUNCTION IB Sports, Exercise and Health Science Topic One: Anatomy APPENDICULAR FUNCTION Investigation 1: A comparison of bone measurements Materials: tape measures, skeleton poster. Task 1 Using a tape measure, on a partner or yourself, measure the circumference of bones at the wrist, elbow, ankle and knee. 1. Make a results table in which it is possible to compare measurements between males and females in the class or group. Results table 1.0: A comparison of bone circumference. name wrist elbow ankle Knee (circumference in cms) IB Sports, Exercise and Health Science Topic One: Anatomy 1. Is the circumference (which is directly related to thickness) of bone an indication of the maturity and strength of bones? Answer Task 2 Bones of males are denser than those of females and the bones of an Afro-Caribbean skeleton are denser than those of the Caucasian skeleton. What effect would this information have when planning a training programme? Answer Investigation 2 Feel around for your hip JOINT below the tissue of your IT band. It helps to sway side to side. Place the measuring tape there and stretch it down the outside of your leg to your knee joint. That's your femur length. 1. Collect the data from males and females, and record the distribution of measurements from all individuals for each category of measurement. Record on a Scatter plot graph- ‘length of femur v’s height’ and a Bar chart – ‘length of arm’. e.g. IB Sports, Exercise and Health Science Topic One: Anatomy Graph 1.1 Scatter plot of length of femur v height Graph 1.2 Bar chart of length of arm 2. Discuss and comment on the distribution of results obtained from different sporting groups, and males as opposed to females. 1.1.4 Neatly draw and annotate the structure of a long bone.

Using the information in Figure 1.7 and 1.8 and answer the following questions: Figure 1.8 Longitudinal section of a typical long bone Figure 1.7 Head of the femur 1. Where in a long bone is spongy bone located? Answer: 2. Why do you think red bone marrow is present in spongy bone? Answer: 3. Answer: Suggest reasons why long bones are hollow. 4. What is the function of the yellow bone marrow located in the diaphysis? Answer: 5. The surface of bones, except for articular surfaces, is covered by the periosteum, which attaches itself to the bone via tiny roots. What do you think are the principle functions of the periosteum? Answer: 6. Comment on the positioning of the articular cartilage. Why is it where it is on the bone?

Dividing the body into left and right halves using an imaginary line gives us the sagittal plane. Any forward and backward movement parallel to this line occurs in the sagittal plane. With the same imaginary line, divide the body into front and back halves and you have the frontal plane. Any lateral (side) movement parallel to the line will occur in the frontal plane. Last, but certainly not least, we have the transverse plane, which divides the body into top and bottom halves. Movement parallel to the waistline, otherwise known as rotational movement, occurs in the transverse plane. For a clearer understanding, we can view the planes as they relate to exercises performed in a workout session. Below are a few exercises performed in each plane.

For example: Structure 1. Articular or hyaline cartilage A smooth, shiny cartilage which covers the ends of bones and absorbs synovial fluid. Answer: F. Function: to prevent friction between bones, when the joint is exercised, synovial fluid is squeezed out of the articular cartilage at the point of contact. (McCutchen's Weeping Lubrication Theory). Structure 2. Joint capsule – a sleeve of fibrous tissue surrounding the joint. Answer: Function: Structure 3. Ligament – a sleeve of tough, fibrous connective tissue, which is an extension of the joint capsule. Answer: Function: Structure 4. Synovial membrane – a sheet of epithelial cells inside the joint capsule. Answer: Function: Structure 5. Synovial fluid – the fluid enclosed in a joint, some of which is absorbed by hyaline cartilage during exercise. Answer: Function: IB Sports, Exercise and Health Science Topic One: Anatomy TASK 2 1. Identify the positions of the bones of the elbow joint (humerus, radius, ulna) and shoulder joint (scapula, clavicle) on a partner. Examples of the types of movements of synovial joints 2. Discuss and list in a table, the joint types and ranges of movements of the elbow and shoulder joints? Answer 3. Two other features that are called bursae and menisci appear in synovial joints. Bursae are little sacs of synovial fluid, and menisci are extra layers of fibrocartilage located at the articulating surfaces of joints. Suggest the functions of these special joint features and give examples from the human body. Answer IB Sports, Exercise and Health Science Topic One: Anatomy Chicken Wing Dissection Chicken Wing Dissection How do the muscles, bones, and tendons work together to move a joint of a chicken wing and how do they compare to a human arm? Although many differences exist between the anatomy of humans and chickens, one structure that shows similarities in muscle pairing and range of motion is a bird’s wing. In this activity you will study chicken wing structure and function, which is comparable to that of the human arm.
