Hypothalamus Location

The hypothalamus is located near the pituitary gland, a small structure connected to the base of the brain.

Hypothalamus Function: Temperature Regulation

The hypothalamus plays a crucial role in regulating body temperature by controlling mechanisms like sweating and shivering.

Hypothalamus Control over Pituitary Gland

The hypothalamus controls the release of hormones from the pituitary gland, the 'master gland', through its own hormone secretions.

Anterior Pituitary Function

The anterior pituitary gland contains cells that respond to signals from the hypothalamus, releasing hormones like growth hormone and ACTH.
