APHY 201 Module 01 Chapter 1 and 3 Ivy Tech Questions with Correct
Answers
Question 1:
Anatomy
Answer:
....Studies the structure of body parts and their relationships to one another.
Question 2:
Physiology (modern definition)
Answer:
....Studies the function of the body, in other words, how the body parts
work and carry out their life sustaining activities. Often focuses on cellular and molecular level.
Question 3:
Physiology (literal definition)
Answer:
....Study of nature
Question 4:
Homeostasis
Answer:
....Maintenance of relatively stable internal environment due to process bringing system back
to baseline. Aka dynamic state of equilibrium or balance.
Question 5:
What is essential to maintain homeostasis?
Answer:
....Communication within the body to monitor and regulate.
All three components (receptor, control center, and effector) must be functional to maintain
homeostasis.
Question 6:
Variable
Answer:
....Homeostasis control mechanism being regulated. Ex: body temperature, heart rate, blood
pressure, oxygen content of blood, blood sugar, etc.
, Question 7:
Receptor
Answer:
....First component: some type of sensor that monitors the environment and responds to
Question 8:
Control center
Answer:
....Second component: receives information (input) from the receptor along the
afferent pathway. Determines the set point, which is the level or range at which a variable is to
be maintained.
Question 9:
Effector
Answer:
....Third component: receives information (output) from the control center along the efferent
pathway. Provides the means for the control centers response (output) to the stimulus.
Question 10:
Afferent
Answer:
....Approaches the control center (monitors)
Question 11:
Efferent
Answer:
....Exits the control center (issues orders to muscles or glands)
Question 12:
Negative feedback
Answer:
....The output shuts off the original effect of the stimulus or reduces its intensity.
Causes the variable to change in a direction opposite to that of the initial change, returning to
its ideal value. If too fast, then slows. If hot, then cools.
