Hypothalamus: Anatomy, Function, Diagram, Conditions

The Hypothalamus Essentials. The portion of the brain that maintains the body's internal balance (homeostasis). The hypothalamus is the link between the endocrine and nervous systems. The hypothalamus produces releasing and inhibiting hormones, which stop and start the production of other hormones throughout the body The hypothalamus is a small brain structure (0.4 percent of total brain volume) primarily of gray matter providing important functions which can be summarized to maintain homeostasis. From an evolutionary perspective, the hypothalamus can be considered a very old component of the central nervous system

Hypothalamic dysfunction is a problem with part of the brain called the hypothalamus. The hypothalamus helps control the pituitary gland and regulates many body functions The hypothalamus is an area of the brain that produces hormones that control: Body temperature; Hunger; Mood; Release of hormones from many glands, especially the pituitary glan Hypothalamus definition, a region of the brain, between the thalamus and the midbrain, that functions as the main control center for the autonomic nervous system by regulating sleep cycles, body temperature, appetite, etc., and that acts as an endocrine gland by producing hormones, including the releasing factors that control the hormonal secretions of the pituitary gland The hypothalamus is located on the undersurface of the brain. It lies just below the thalamus and above the pituitary gland, to which it is attached by a stalk.It is an extremely complex part of the brain containing many regions with highly specialised functions

  1. The hypothalamus is a small but important area of the brain formed by various nucleus and nervous fibers. Through its neuronal connections, it is involved in many complex functions of the organism such as vegetative system control, homeostasis of the organism, thermoregulation, and also in adjusting the emotional behavior. The hypothalamus is involved in different daily activities like eating.

It plays a major role in regulating hormones, the pituitary gland, body temperature, the adrenal glands, and many other vital activities The hypothalamus is an area of the brain that has many functions despite its small size. It plays an important role in the production of hormones. In addition, it helps stimulate many important processes. Thus, when the hypothalamus doesn't work properly, it can cause organic problems that can lead to many disorders The hypothalamus generally restores homeostasis through two mechanisms. First, it has connections to the autonomic nervous system, through which it can send signals to influence things like heart rate, digestion, and perspiration.For example, if the hypothalamus senses that body temperature is too high, it may send a message to sweat glands to cause perspiration, which acts to cool the body down
