Anatomy and Physiology: Homeostasis, Body Regions, Planes, and Cavities

Fill-in-the-blank practice flashcards reviewing homeostatic feedback mechanisms, body planes, anatomical regions, and body cavities.

In a general homeostatic control system, step 1 occurs when a __________ produces a change in a variable.

stimulus

In a homeostatic mechanism, information is sent along the __________ pathway from the receptor to the control center.

afferent

Information sent from the control center to an effector travels along the __________ pathway.

efferent

In the general homeostatic balance diagram shown below, step 4 shows output being sent along the efferent pathway to the __________.

effector

When body temperature rises, the thermoregulatory center in the brain signals the __________ to serve as effectors.

sweat glands

When cold temperature causes body temperature to fall, the thermoregulatory control center sends signals to the __________ as effectors to begin shivering.

skeletal muscles

Temperature-sensitive cells that act as receptors in thermoregulation are located in the __________ and brain.
