BIOL 251 Human Anatomy & Physiology I (with
Lab) – Module 1 Exam Questions And Answers
|Portage Learning Grade A+.
Foundations of Anatomy & Physiology
1. What is anatomy?
The study of the structure of body parts and their relationships to one
another.
2. What is physiology?
The study of how body parts function and work together.
3. What is the relationship between anatomy and physiology?
Structure determines function; form supports physiological processes.
4. What level of organization is the simplest?
Chemical level.
5. What level of organization includes cells working together?
Tissue level.
6. What is the highest level of organization in the human body?
Organism level.
7. Define homeostasis.
The ability of the body to maintain a stable internal environment.
8. What body system regulates homeostasis?
The nervous and endocrine systems.
9. What is a stimulus?
Any change in the internal or external environment.
10. What is a receptor in a feedback system?
A structure that detects changes.
Feedback Mechanisms
11. What is negative feedback?
A mechanism that reverses a change to maintain stability.
12. Give an example of negative feedback.
Regulation of body temperature.
13. What is positive feedback?
A mechanism that amplifies a change.
14. Give an example of positive feedback.
Blood clotting.
, 15. Which type of feedback is more common in the body?
Negative feedback.
Anatomical Position & Terminology
16. Describe the anatomical position.
Standing upright, facing forward, arms at sides, palms facing forward.
17. What does anterior mean?
Toward the front.
18. What does posterior mean?
Toward the back.
19. What does medial mean?
Toward the midline.
20. What does lateral mean?
Away from the midline.
21. What does proximal mean?
Closer to the point of attachment.
22. What does distal mean?
Farther from the point of attachment.
23. What does superficial mean?
Toward the surface.
24. What does deep mean?
Away from the surface.
Body Planes & Sections
25. What is a sagittal plane?
Divides the body into left and right.
26. What is a midsagittal plane?
Divides the body into equal left and right halves.
27. What is a frontal (coronal) plane?
Divides the body into anterior and posterior portions.
28. What is a transverse plane?
Divides the body into superior and inferior portions.
Body Cavities & Membranes
29. What is the dorsal body cavity?
Contains the brain and spinal cord.
30. What cavities make up the ventral cavity?
Thoracic and abdominopelvic cavities.
