Hypothalamus


The hypothalamus is located in the central bottom portion of the brain, just below the thalamus.
The hypothalamus directs a number of important functions in the body. It is the control center for many autonomic functions of the peripheral nervous system. In addition, certain nerve cells in the hypothalamus control the endocrine system through the pituitary gland, located directly below the hypothalamus. The hypothalamus relays information sensed by the brain to the pituitary gland using neurohormones.Connections between the edocrine and nervous system enable the hypothalamus to play a vital role in maintaining the body's homeostasis. As part of the limbic system, the hypothalamus influences several emotional responses. For example, the hypothalamus is involved in controlling functions such as hunger, thirst, and sexual behavior. It also controls the body's reactions to changes in temperature, so when we are warm, we begin to sweat, and when we are cold, we shiver.
