Maintenance of stable internal condition involves continuous monitoring and regulation
Homeostasis
Stimulus, receptor, input, control center, output, effector
What are the feedback components?
produces change in variable
stimulus
detects change in environment
receptor
information sent along afferent pathway to control center
input

control center
information sent along efferent pathway to effector
output
response of effector feeds back to reduce the effect of stimulus and return variable to
homeostasis
response
