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.

, Anatomy Studies the structure of body parts and their relationships to one another.
Physiology (modern definition) 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.
Physiology (literal definition) Study of nature
Homeostasis Maintenance of relatively stable internal environment due to process bringing
system back to baseline. Aka dynamic state of equilibrium or balance.
What is essential to maintain homeostasis? Communication within the body to monitor and regulate. All three components
(receptor, control center, and effector) must be functional to maintain
homeostasis.
Variable Homeostasis control mechanism being regulated. Ex: body temperature, heart
rate, blood pressure, oxygen content of blood, blood sugar, etc.
Receptor First component: some type of sensor that monitors the environment and
responds to changes called stimuli, by sending information (input) to the control
center.
Control center 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.
Effector 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.
Afferent Approaches the control center (monitors)
Efferent Exits the control center (issues orders to muscles or glands)
Negative feedback 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.
Body temperature and blood sugar are regulated by Negative feedback mechanism
what?
Main goal for negative feedback mechanisms? To prevent sudden severe changes within the body.
