Introduction: What Do You Know About The Human Body?

Chap 1 Orientation To The Human Body

Homework: Read Chap 1(all) in your textbook. Review and learn directional terms (pg 13) and regional terms (pg. 14) that describe 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.

The Human Body…What is it? How does it work? Let’s operate and find out!

Problem-Solving Scenario

NOTE: To Be Presented in Class

Homeostasis, page 8

• The body’s ability to maintain a relatively _____ _____ _______ 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

• As you study this figure, determine precisely where you would be injured if you pulled a muscle in your __________ region?

PREDICT• Where would you be

injured if you cracked a bone in your __________ region?

PREDICT• What if you cut

your ________ region?

EXPLORING REGIONAL TERMS• Regional terms, like the

ones we just discussed, are used to designate specific body areas.

• Using your textbook as a reference (page 14), identify and learn the regions of the human body on the handout provided by the instructor.

• Estimated Time 10 – 12 minutes

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.

Discussion
