The cell bodies of the neurons that produce these neurohormones are not evenly distributed throughout the hypothalamus. Instead, they are grouped together in paired clusters of cell bodies known as nuclei.
A classic model for neurohormonal activity is the posterior lobe of the pituitary gland neurohypophysis. Its secretory products, vasopressin and oxytocin, are produced and packaged into neurosecretory granules in specific groups of nerve cells in the hypothalamus the supraoptic nuclei and the paraventricular nuclei.
The granules are carried through the axons that extend through the infundibular stalk and end in and form the posterior lobe of the pituitary gland.
In response to nerve signals, the secretory granules are extruded into a capillary network that feeds directly into the general circulation.
The hypothalamus also regulates body heat in response to variations in external temperature, determines wakefulness and sleep , and regulates fluid intake and sensation of thirst.
Injuries or diseases affecting the hypothalamus may produce symptoms of pituitary dysfunction or diabetes insipidus ; in the latter disorder, the absence of vasopressin , which promotes the reabsorption of water in the kidneys, induces the rapid loss of water from the body through frequent urination.

Hypothalamus Overview. Medically reviewed by Seunggu Han, M. To maintain homeostasis, the hypothalamus is responsible for creating or controlling many hormones in the body.
The hypothalamus works with the pituitary gland, which makes and sends other important hormones around the body. Together, the hypothalamus and pituitary gland control many of the glands that produce hormones of the body, called the endocrine system.
This includes the adrenal cortex, gonads, and thyroid. The hypothalamus also directly influences growth hormones.
It commands the pituitary gland to either increase or decrease their presence in the body, which is essential for both growing children and fully developed adults.
A hypothalamic disease is any disorder that prevents the hypothalamus from functioning correctly. These diseases are very hard to pinpoint and diagnose because the hypothalamus has a wide range of roles in the endocrine system.
The hypothalamus also serves the vital purpose of signaling that the pituitary gland should release hormones to the rest of the endocrine system.
As it is difficult for doctors to diagnose a specific, incorrectly functioning gland, these disorders are often called hypothalamic-pituitary disorders.
In these cases, there are some hormone tests that doctors might prescribe to get to the root of the disorder. The most common causes of hypothalamic diseases are injuries to the head that impact the hypothalamus.
Surgeries, radiation, and tumors can also cause disease in the hypothalamus. Read it at Google Books - Find it at Amazon. Edit article Share article View revision history Report problem with Article.
