Chap 1 Orientation to the Human Body(2)

Introduction: What
Do You Know About
The Human Body?
The Human Body…What is it? How
does it work? Let’s operate and find out!
Chap 1 Orientation To The Human Body
Learning Objectives:
1. Explain the significance of homeostasis.
2. Describe the “anatomical position”.
3. Use correct anatomical terms to describe body directions, regions, and
body planes or sections.
Homework: Read Chap 1 in The Anatomy Assignment. Review
and learn the regional terms that describe the human body.
Problem-Solving Scenario
Assume that the temperature outside is 36
degrees Fahrenheit. You are asked to
stand outside, with only shorts and a t-shirt
on for 4 hours.
If we took your temperature with a normal
thermometer, what should we expect your
body temperature to be at the end of those
4 hours? Why?
Homeostasis, page 2
The Anatomy Assignment
• The body’s ability to maintain a relatively
stable internal environment despite
outside conditions
• There are hundreds of systems and
processes that the body attempts to
maintain to stay at homeostasis including
- body temperature
- blood volume
- heart rate
- blood pressure
- breathing
- levels of oxygen
in the blood
Medical Science
Our bodies are complex to say the least.
Medical science attempts to organize the
body in such a way that we can study and
understand it.
What do you know about your body?
• As you study this
figure, determine
precisely where
you would be
injured if you
pulled a muscle in
your inguinal
Inguinal (groin)
• Where would you be
injured if you cracked
a bone in your
olecranal region?
Olecranal (back
of elbow)
• What if you cut
your fibular
Fibular or
peroneal (side
of leg)
• Regional terms, like the
ones we just discussed,
are used to designate
specific body areas.
• Using your textbook as a
reference (page 15-16),
identify and learn the
regions of the human
body on the handout
provided by the instructor.
• Estimated Time 10 – 12
Regions of the Body
The “anatomical position” is palms up (anterior view). And soles of feet slightly raised to
show the plantar surface of the foot.
• What does “dorsal” refer to?
A - On the back
What term do we use to refer to the
stomach surface of an animal?
A - Ventral
Partner Activity: Other Directional Terms
Instructions: Using your textbook, Table 1.1 – Orientation and Directional
Terms page 13, briefly describe the meaning of the term in your notes. Do
this with a partner.
What do these terms refer to?
1. Superior
2. Inferior
3. Medial
4. Lateral
5. Intermediate
6. Proximal
7. Distal
8. Superficial
9. Deep
1. Toward the head
2. Away from the head
3. Toward the midline
4. Away from the
5. Between
6. Close to the point of
attachment of a limb
7. Farther from the
point of attachment
8. Toward or at the
body’s surface
9. Away from the
body’s surface
Planes of the Body, page 5
The body is often sectioned (cut) along a flat surface called a plane.
Which of these
planes would
separate the
woman’s arms?
