The Main Center for Homeostatic Control of the Internal Environment

Question

The main center for homeostatic control of the internal environment is the ____.  
A) pons
B) medulla oblongata
C) hypothalamus
D) thalamus
E) cerebellum

Accepted Answer

The hypothalamus is the main center for homeostatic control of the internal environment. It receives input from various receptors, such as those involved in temperature regulation, thirst, hunger, and satiety, and then triggers appropriate responses to maintain a stable internal environment. The pons, medulla oblongata, thalamus, and cerebellum are all involved in various functions such as breathing, sensation, coordination, and balance, but they are not the main center for homeostatic control.
