The pituitary gland is a small gland that sits in the sella turcica (Turkish saddle), a bony hollow in the base of the skull, underneath the brain and behind the bridge of the nose. The pituitary gland has two main parts, the anterior pituitary gland and the posterior pituitary gland. The gland is attached to a part of the brain (thePituitary Gland. The pituitary gland, or hypophysis, is about the size of a pea and sits in the small, bony cavity (sella turcica) at the base of the brain. The pituitary gland is divided into two sections: the anterior lobe (adenohypophysis) and the posterior lobe (neurohypophysis). posterior pituitary gland stores and secretes

The posterior pituitary gland does not produce hormones, but rather stores and secretes hormones produced by the hypothalamus. Neurons of the paraventricular nucleus produce the hormone oxytocin, whereas neurons of the supraoptic nucleus produce ADH.

The pituitary is functionally connected to the hypothalamus by a small tube called the infundibular stem, or, pituitary stalk. The pituitary gland secretes hormones that regulate homeostasis. The pituitary gland is divided into two parts, the anterior pituitary and the posterior pituitary. This gland does not synthesize hormones. Instead the posterior pituitary stores and secretes two hormones, oxytocin and vasopressin, which are actually produced in the hypothalamus (master gland) and transported to the pituitary. posterior pituitary gland stores and secretes Endocrine System Hormones, Glands& Vocab. AP Biology Test; Mosley& Downing. the slightly smaller part of the pituitary gland; stores and secretes Oxytocin and Antidiuretic Hormone (ADH) [Posterior Pituitary Gland stimulates contraction of uterus and mammary gland cells.

The posterior pituitary gland does not produce hormones, but rather stores and secretes hormones produced by the hypothalamus. The paraventricular nuclei produce the hormone oxytocin, whereas the supraoptic nuclei produce ADH. posterior pituitary gland stores and secretes Women: The posterior pituitary gland secretes oxytocin which stimulates contraction of the uterus and dilation of the cervical canal. This is why sexual abstention is advised when there is a high risk for miscarriage or preterm labor. The egg only lives for 24 hours after ovulation. The posterior pituitary (or neurohypophysis) is the posterior lobe of the pituitary gland which is part of the endocrine system. The posterior pituitary is not glandular as is the anterior pituitary. Instead, it is largely a collection of axonal projections from the hypothalamus that terminate behind the anterior pituitary, and serve as a site for the secretion of neurohypophysial hormones
