Definition
The hypothalamus is a small region of the brain that serves as the main control center for autonomic functions. It plays a crucial role in many important functions, including releasing hormones and regulating body temperature.
This is often called the "master gland" because it controls other glands' activities in the endocrine system, including those controlled by the hypothalamus.
