What is the Complementarity of Structure and Function
|
Function is dependent on structure; the form of a structure relates to its function.

Define Homeostasis
|
Body's desire and ability to maintain a stable internal enviroment
|
|
Name and describe the 4 components of Homeostasis
|
Variable= regulated factor
Receptor = structure that monitors change & sends information to brain
Control center = brain; determines set point, analyzes and decides on response
Effector = structor that carries out response
|
|
Name the 5 parts of the Pathway of Homeostasis
|
Stimulus (action of variable)
Receptor
Input along afferent path (from receptor)
Output along efferent path (from brain)
Response by effector
|
|
Define Negative Feedback Mechanism
|
Will reverse the original trend. (negative means it will cancel out what happens.)
|
|
What systems are important to the Negative Feedback Mechanism.
|
Nervous and Endocrine systems. Hormones are released to regulate function.
