Ch. 1 Homeostasis and Homeostatic Mechanisms of Control

Homeostasis can be defined as the:
A. Overall contribution of an organ system
B. External stimuli that evoke a disruption to an organism
C. Relatively constant state maintained by the body
D. Lack of cytoplasm within a plasma membrane

Which of the following is NOT a component of a feedback control loop?
A. Sensory mechanism C. Effector mechanism
B. Integrating, or control center D. Stressor stimulator

negative feedback control systems:
A. Oppose a change C. Ignore a change
B. Accelerate a changed. D. None of the above

Positive feedback control systems:
A. Oppose a change C. Ignore a change
B. Accelerate a change D. None of the above

True or False
Any given physiological parameter will never deviate beyond the set point.

True or False
In the thermostatically regulated furnace example of negative feedback, the furnace
functions as the sensor.

True or False
Negative feedback systems are inhibitory.

True or False
The process of childbirth, in which the baby’s head causes increased stretching of the
reproductive tract, which in turn feeds back to the brain, thus triggering the release
of oxytocin, is an example of positive feedback
