Endocrine System KEY TERMS
.........................................
Control center
—The center that receives messages from receptors about a change in the
body's internal conditions and relays messages to effectors to change their
function to correct the deviation; in most homeostatic mechanisms, the
control center is the brain.
Effector
—A muscle or organ that receives messages from the control center to
change its function in order to correct a deviation in the body's internal
conditions.
Hormone
—Chemical regulator of physiology, growth, or development which is
typically synthesized in one region of the body and active in another and is
typically active in low concentrations.
Negative feedback loop
—A homeostatic mechanism that opposes or resists a change in the body's
internal conditions.
Positive feedback loop
—A mechanism that increases or enlarges a change in the body's internal
conditions.
Receptor
—A structure that monitors the body's internal functions and conditions;
detects changes in the body's internal environment.
Set point
—The range of normal functional values of an organ or structure.
