Anterior Hypothalamus
The Anterior Hypothalamus (pronunciation: an-TEER-ee-or hy-po-THAL-uh-muhs) is a region of the brain that plays a crucial role in many physiological processes.
Etymology
The term "Anterior Hypothalamus" is derived from the Latin words 'anterior' meaning 'front' and 'hypothalamus' which is a combination of 'hypo' meaning 'under' and 'thalamus' meaning 'inner room'. This refers to its location in the brain, beneath the thalamus.
Function
The Anterior Hypothalamus is involved in a variety of functions including thermoregulation, sleep regulation, sexual behavior, and hunger and thirst responses. It is also responsible for the regulation of the autonomic nervous system and the endocrine system, and plays a role in emotion and memory.
