While the posterior pituitary is not a "gland" per se, this section of the pituitary releases 2 hormones. The first is called Oxytocin, while the second is known as Argenine Vasopressin
Oxytocin is sometimes commonly called the "love hormone", and is responsible for mutliple facets of bodily functions. In females, it specifically aids in the distension of the cervix and uterus during labor, and also stimulates the nipples, for breastfeeding. It also may assist in orgasms, pair bonding, and maternal behaviors.
Argenine Vasopressin, or AGV for short, is responsible for such functions as regulating materials such as water and salt, and glucose in the bloodstream. It also controls and regulates the absortion of molecules in the tubulars of the kidneys. It also has an effect on pair bonding and aspects of social behaviors.

What is the storehouse for the hormones produced by the hypothalamus of the brain?
The Posterior Lobe of Pituitary and the HypothalamusThe posterior lobe, so far as is known, does not make any of its own hormones, but serves as a storehouse for two hormones manufactured by the hypothalamus . The hypothalamus, apart from having a role in controlling the body's autonomic nervous system, also functions as an endocrine gland, secreting its own hormones, and as a connecting link between the brain's cerebral cortex and the pituitary gland. The posterior lobe of the pituitary releases the two hormones it receives from the hypothalamus, called vasopressin and oxytocin , into the bloodstream. Vasopressin plays a role in the fluid balance of the body; oxytocin is thought to pace the onset and progress of labor during childbirth.
Where is the posterior pituitary gland located?
The posterior pituitary is located in a portion of the sphenoid bone called the sella turcica. It is attached to the anterior pituitary gland by the pars intermedia which is a thin layer of endocrine tissue. The posterior pituitary is actually just an extension of the neural tissue that composes the hypothalamus.
What gland is also called the neurohypophysis?
An adenohypophysis is the anterior lobe of the pituitary gland, which produces and secretes peptide hormones which regulate many physiological processes.
How is the anterior pituitary connected to the hypothalamus?
The anterior pituitary is connected to the hypothalamus through a network of blood vessels called the hypothalamic-hypophyseal portal system. This system allows hormones produced by the hypothalamus to be transported directly to the anterior pituitary where they can regulate the release of pituitary hormones into the bloodstream.
What hormone is released from the posterior pituitary gland?
The posterior pituitary gland does not actually produce any hormones, instead they are produced by the hypothalamus, then stored in the posterior pituitary which releases them when they are needed. The two hormones stored and released by the posterior pituitary are Oxytocin and Antidiuretic Hormone or vasopressin. The function of Oxytocin is to produce uterine contractions before and after child birth and also to eject milk during breast feeding. Antidiuretic Hormone (ADH) also known as vasopressin, controls the production of urine. If we are dehydrated, then ADH is released and inhibits the production of urine, leaving more fluid available to circulate around the body.
What is the function of the posterior pituitary gland?
The posterior pituitary is made up of axons belonging to cells called neurosecretory cells, whose cell bodies are in the hypothalamus. When these cell bodies are stimulated, the axons in the posterior pituitary releases their hormones into the blood stream. In a way, the posterior pituitary is an extension of the hypothalamus.
Where is the posterior pituitary gland located?
The posterior pituitary is located in a portion of the sphenoid bone called the sella turcica. It is attached to the anterior pituitary gland by the pars intermedia which is a thin layer of endocrine tissue. The posterior pituitary is actually just an extension of the neural tissue that composes the hypothalamus.
What gland releases posterior pituitary?
The posterior pituitary consists mainly of neuronal projections (axons) extending from thesupraoptic and paraventricular nuclei of the hypothalamus. These axons release peptide hormones into the capillaries of the hypophyseal circulation. In addition to axons, the posterior pituitaryalso contains pituicytes, specialized glial cells resembling astrocytes.Classification of the posterior pituitary varies, but most sources include the three regions below:Pars nervosaAlso called the neural lobe or posterior lobe, this region constitutes the majority of the posterior pituitary, and is sometimes (incorrectly) considered synonymous with it. Notable features include Herring bodies and pituicytes.[2]Infundibular stalkAlso known as the infundibulum or pituitary stalk, the infundibular stalk bridges the hypothalamic and hypophyseal systems.Median eminenceThis is only occasionally included as part of the posterior pituitary. Other sources specifically exclude it from the pituitary.[3]A few sources include the pars intermedia as part of the posterior lobe, but this is a minority view. It is based upon the gross anatomical separation of the posterior and anterior pituitary along the cystic remnants of Rathke's pouch, causing the pars intermedia to remain attached to the neurohypophysis.

How does the anterior pituitary regulate the thyroid gland?
The hypothalmus is connected to the pituitary by the hypophyseal portal system. This is a network of capillary beds that allows the hypothalmus to control the release of hormones from the anterior and posterior pituitaryThe two pituitary lobes are the dual origin of the hypothalmus. The posterior pituitary lobe is part of the brain and is a "downgrowth" of hypothalmic tissue and maintains a neural connection with the hypothalmus through a nerve bundle called the hypothalamic-hypophyseal tract. This arises from neurons of the hypothalmus. These cells synthesize two neurohormones and transport them along their axons to the posterior pituitary. Then these neurons "fire" they release the stored hormones into a capillary bed in the posterioir pituitary for distribution throughout the body.The hypothalamus is connected to the pituitary gland by both blood vessels and neural tissue. The posterior pituitary is actually part of the brain and receives input from the hypothalamus via neural connections. The anterior pituitary gland is controlled by the hypothalamus when the latter releases tropic hormones (hormones that control release of other hormones) into the blood portal. The hormones diffuse through the blood and act on the anterior pituitary gland, initiated the release of subsequent hormones.The hypothalamus controls both the anterior and posterior pituitary functioning with neurosecretions that either release or inhibit hormones. These secretions are produced in the ventral hypothalamus
What is the posterior pituitary called?
It is also called the neurohypophysis.
Why is the anterior pituitary called the master gland?
An endocrine gland is any organ that secretes chemicals (called hormones) into the blood. The hypothalamus releases several hormones, including corticotropin-releasing hormone, thyrotropin-releasing hormone, growth hormone-releasing hormone, oxytocin, antidiuretic hormone, and a bunch of others. Because many of these hormones regulate the activity of the pituitary gland, which is often called the master regulator of the endocrine system, the hypothalamus is often considered the ultimate regulator of the endocrine system.
How is the anterior pituitary connected to the hypothalamus?
The anterior pituitary is connected to the hypothalamus through a network of blood vessels called the hypothalamic-hypophyseal portal system. This system allows hormones produced by the hypothalamus to be transported directly to the anterior pituitary where they can regulate the release of pituitary hormones into the bloodstream.

What is an other name for anterior lobe of the pituitary gland?
It is also called the neurohypophysis. ADH and oxytocin are produced in the hypothalamus. These are stored in the posterior pituitary. No hormones are actually produced in the posterior pituitary, they are only stored.
What connects the hypothalamus to the posterior pituitary?
By using the gravilite projectiles aiming stimulation towards your reluctent postual clavicle, streaming straight to your phalanges causing major damage, or as the sloppy male likes to call it "you'll be like a babe on he rags"
