How do releasing hormones of the hypothalamus connect the nervous and endocrine system?
Hypothalamus controls the posterior pituitary gland which is connected with axons. Thus the hypothalamus synthesizes oxytocin and anti-diuretic hormones which are then packaged in secretory vesicles and moved to axons. When axon terminals are triggered, the hormones are released in the capillaries of posterior pituitary.
Where are the hormones oxytocin and antidiuretic hormone (ADH) stored?
Oxytocin and antidiuretic hormone (ADH) are produced in the hypothalamus and stored in the posterior pituitary gland. When needed, these hormones are released into the bloodstream from the posterior pituitary. This storage mechanism allows for quick release in response to physiological signals.
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.
Does the posterior pituitary gland respond to the gonadotropin-releasing hormone?
No, the posterior pituitary gland does not respond to gonadotropin-releasing hormone (GnRH). The posterior pituitary mainly secretes oxytocin and vasopressin, which are produced in the hypothalamus and stored in the posterior pituitary before being released into the bloodstream. GnRH primarily acts on the anterior pituitary gland to regulate the release of gonadotropins like luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
What is secreted by the neurosecretory cells in the posterior lobe of the pituitary gland?
The posterior pituitary has neurosecretory tissue. It is activated by impulses from the hypothalamus and release hormones such as oxytocin and ADH.

How the two hormones arrive in the posterior pituitary?
Oxytocin and vasopressin are synthesized in the hypothalamus and transported to the posterior pituitary through nerve fibers known as hypothalamic-hypophyseal tract. These hormones are then stored in the nerve terminals until they are released into the bloodstream in response to appropriate signals or stimuli.
Where are the hormones oxytocin and antidiuretic hormone (ADH) stored?
Oxytocin and antidiuretic hormone (ADH) are produced in the hypothalamus and stored in the posterior pituitary gland. When needed, these hormones are released into the bloodstream from the posterior pituitary. This storage mechanism allows for quick release in response to physiological signals.
What cells produce hormones that are released by the Hypotharamus gland?
The hypothalamus itself produces hormones that are released directly into the bloodstream. These hormones include releasing and inhibiting hormones, which regulate the function of the pituitary gland. Specific neurosecretory cells in the hypothalamus, such as paraventricular and supraoptic neurons, synthesize hormones like oxytocin and vasopressin (antidiuretic hormone) that are stored and released from the posterior pituitary.
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.

Which hormones are secreted by your posterior pituitary gland?
Antidiauretic hormone and Oxytocin are the two hormones released by posterior Pituitary gland. A.D.H. conserve the body water by reducing amount of urine. Oxytocin increases the milk secretion and to induce delivery you put a drip of Oxytocin. It promotes uterine contractions and relaxes the cervix to hasten delivery.
What are the two hormones that are produced in the hypothalamus but stored in the pituitary?
The two hormones are oxytocin and vasopressin (antidiuretic hormone). They are produced in the hypothalamus and then transported and stored in the posterior pituitary gland until they are released into the bloodstream.
Where is Anti-diuretic hormone produced?
ADH is released by the brain's pituitary gland.ADH is not produced in the pituitary gland.it is made in the hypothalamus and secreted by the posterior pituitary its hypothalmus
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.
