- Definition of Antidiuretic hormone (ADH) Antidiuretic hormone (ADH): A relatively small (peptide) molecule that is released by the pituitary gland at the base of the brain after being made nearby (in the hypothalamus). ADH has an antidiuretic action that prevents the production of dilute urine (and so is antidiuretic). A syndrome of inappropriate secretion of ADH results in the inability to put out dilute urine, perturbs fluid (and electrolyte) balance, and causes nausea, vomiting, muscle cramps, confusion and convulsions.

- Vasopressin (arginine vasopressin, AVP; antidiuretic hormone, ADH) is a peptide hormone formed in the hypothalamus, then transported via axons to, and released from, the posterior pituitary into the blood. AVP has two principle sites of action: the kidney and blood vessels.

The Antidiuretic Hormone Blood Test The antidiuretic hormone (ADH), also known as vasopressin, is a hormone produced by the pituitary gland in the brain. As the name suggests, the primary function of this hormone is to control the amount of urine passed out from the body by controlling the amount of water reabsorbed by the kidneys.

ADH (Antidiuretic Hormone) ADH (Antidiuretic Hormone). The brain and kidneys regulate the amount of water excreted by the body. When the blood volume is low, the concentration of solutes in the blood is high. When the hypothalamus senses this low blood volume and increased serum osmolality it synthesizes ADH, a small peptide molecule.The pituitary gland then releases ADH into the bloodstream and causes the kidneys to retain water by concentrating the urine and reducing urine volume.DH (continued). Increased blood volume prevents the release of ADH. As a result, the kidneys retain less water, which dilutes the urine and increases urine output.

Releasing and Inhibiting Hormones 1. Corticotropin Releasing Hormone (CRH) is released from the hypothalamus in response to stress or low blood glucose. It passes through the hypothalamohypophyseal portal system to the anterior pituitary 2. CRH stimulates the secretion of Adrenocorticotropic Hormone (ACTH) from the anterior pituitary 3.

Hypothalamus The hypothalamus produces and secretes not only neurotransmitters and neuropeptides but also several neurohormones that alter anterior pituitary gland function and two hormones, vasopressin (antidiuretic hormone) and oxytocin, that act on distant target organs.

An Overview of the Adrenal Glands When the hypothalamus produces corticotrophin-releasing hormone (CRH), it stimulates the pituitary gland to release adrenal corticotrophic hormone (ACTH). These hormones, in turn, alert the adrenal glands to produce corticosteroid hormones.

Hormone secretion from the anterior pituitary gland is regulated by releasing hormones secreted by the hypothalamus.

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) The syndrome of inappropriate antidiuretic hormone secretion (SIADH) involves the excessive secretion of antidiuretic hormone (ADH) from the posterior pituitary gland or another source.

Antidiuretic Hormone The most important variable regulating antidiuretic hormone secretion is plasma osmolarity, or the concentration of solutes in blood. Osmolarity is sensed in the hypothalamus by neurons known as an osmoreceptors, and those neurons, in turn, stimulate secretion from the neurons that produce antidiuretic hormone.

ADH Antidiuretic hormone, also called arginine vasopressin (AVP), is a hormone produced by the hypothalamus in the brain and stored in the posterior pituitary gland at the base of the brain. ADH helps regulate water balance in the body.entral diabetes insipidus is a decrease in the production of ADH by the hypothalamus or in the release of ADH from the pituitary while nephrogenic diabetes insipidus is characterized by a decrease in the kidney's response to ADH.

Overview The hormone is stored in and released by the pituitary gland. ADH controls how your body releases and conserves water. When ADH (also called vasopressin) is produced somewhere other than the hypothalamus, the condition is called syndrome of inappropriate antidiuretic hormone (SIADH). In addition to making it harder for your body to release water, SIADH can result in lowered levels of electrolytes like sodium.
