Homeostatic regulation involves three parts or mechanisms: 1) the receptor, 2) the control center and 3) the effector. The receptor receives information that something in the environment is changing. The control center or integration center receives and processes information from the receptor.
The hypothalamus plays a significant role in the endocrine system. It is responsible for maintaining your bodyâs internal balance, which is known as homeostasis. To do this, the hypothalamus helps stimulate or inhibit many of your bodyâs key processes, including: 1  Heart rate and blood pressure. 2  Body temperature.
