What is hypothalamus and the posterior pituitary are joined by?
The hypothalamus and the posterior pituitary are joined by the pituitary stalk, also known as the infundibulum. This structure allows for communication between the hypothalamus and the posterior pituitary gland, enabling the release of hormones like oxytocin and vasopressin into the bloodstream.
What are the two sections of the pituitary?
The pituitary gland is divided into two sections: the anterior pituitary (adenohypophysis) and the posterior pituitary (neurohypophysis). The anterior pituitary produces and releases hormones that regulate various physiological processes, while the posterior pituitary stores and releases hormones produced by the hypothalamus.
What organ contains target cells for oxytocin?
Oxytocin is released by posterior pitutory.It is produced by hypothalamus.
What hormones are made by the posterior pituitary?
The posterior pituitary gland only produces two hormones. It produces antidiuretic hormone (vasopressin) and oxytocin.
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.
What is the anotomical relationship between the hypothalamus and posterior pituitary?
They are attached by infundibulum , posterior pituitary is actually continuation of 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.
How does the anterior and posterior pituitary differ?
The anterior pituitary produces and secretes its own hormones in response to releasing hormones from the hypothalamus, while the posterior pituitary stores and releases hormones produced by the hypothalamus. The anterior pituitary is derived from glandular tissue, while the posterior pituitary originates from neural tissue.
What hormone promotes reabsorstion of water?
That is andeuratic hormone. ADH. It is secreted by posterior pituitary.
What are Oxytocin and ADH secreted by?
The posterior lobe of the pituitary gland in the brain.
Which part of the pituitary gland is for storage only?
The posterior pituitary (or neurohypophysis)
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 are the two parts of the pituitary gland?
The parts of the pituitary gland are the adenohypophysis (anterior) gland and the neurohypophysis (posterior)

Does the hypothalamus communicate with the posterior pituitary?
yes
