Hypothalamus

From WikiMD.com - Food, Medicine & Wellness Encyclopedia

(Redirected from Hypothalamic)

Hypothalamus is a small region of the brain that serves as the main control center for many functions of the autonomic nervous system. It plays a crucial role in many important functions, including releasing hormones, regulating body temperature and maintaining daily physiological cycles.

Function[edit | edit source]

The hypothalamus is responsible for the regulation of certain metabolic processes and other activities of the Autonomic Nervous System. It synthesizes and secretes certain neurohormones, often called hypothalamic-releasing hormones, and these in turn stimulate or inhibit the secretion of pituitary hormones.

Anatomy[edit | edit source]

The hypothalamus is located below the thalamus and right above the brain stem. It forms the ventral part of the diencephalon. All vertebrate brains contain a hypothalamus. In humans, it is roughly the size of an almond.

Hypothalamic Hormones[edit | edit source]

The hypothalamus produces several releasing and inhibiting hormones that act on the pituitary gland, signaling it to release hormones that affect growth, mood, and the reproductive cycle.

Disorders[edit | edit source]

Disorders of the hypothalamus can lead to a range of problems. For example, damage to the hypothalamus may result in disruptions to the body’s thermoregulation, causing hypothermia or hyperthermia. Other disorders include hypopituitarism, hypothyroidism, and diabetes insipidus.
