BIO 2401: Anatomy and Physiology
(Test 1) -TCC Questions and Answers.
Anatomy - Answer the structure of body parts and their relationship to one another
Physiology - Answer concerns the function of the body
Gross Anatomy - Answer - Study of large structures visible to the naked eye
-regional anatomy
-systemic anatomy
-surface anatomy
Microscopic Anatomy - Answer deals with structures too small to be seen with the naked eye
-cytology
-histology
-embryology
Describe how form and function are related - Answer form determines function
-principle of complementarity of structure and function
Major Organizational Levels of the Body - Answer 1. Atoms
2. Molecules
3. Organelles
4. Cells
5. Tissues
6. Organs
7. Organ Systems
8. Organisms
7 necessary functions for life - Answer 1. Maintaining boundaries
2. Movement
3. Responsiveness
4. Digestion
, 5. Metabolism
6.Excretion
7. Reproduction
8. Growth
Homeostasis - Answer ability to maintain relatively stable internal conditions.
Law of Mass Balance - Answer Amount of substance the body takes in must be equal to the
amount that leaves the body
homeostasis communication - Answer 1. receptor
2. control cnter
3. Effector
Homeostasis: Receptor - Answer - monitors environment
- responds to stimuli
- sends info along the afferent pathway
Homeostasis: Control Center - Answer -Determines set point
-Analyzes input
-Determine appropriate response
-Info flows down the efferent pathway
Homeostasis: Effector - Answer -carries out response from the control center
-the results from the response than feed back to influence the effect of the stimulus.
Negative Feedback - Answer output shuts off the original effect of the stimulus or reduces it's
intensity
-variable changes in opposite direction
Positive Feedback - Answer Referred to as cascades
- Good positive feedback: labor and blood clotting
Feedforward Responses - Answer Maintains homeostasis by anticipating change & taking
action
