Located at the base of the brain, the pituitary gland is protected by a bony structure called the sella turcica(also known as turkish saddle)of the sphenoid bone.
The pituitary gland, or hypophysis, is an endocrine gland about the size of a pea that sits in a small, bony cavity (sella turcica) covered by a dural fold (diaphragma sellae) at the base of the brain. The pituitary gland secretes hormones regulating homeostasis, including trophic hormones that stimulate other endocrine glands.
The hypophysis is also the top cell of the suspensor in a dicot embryo, which will differentiate to form part of the root cap.
Located at the base of the brain, the pituitary is functionally linked to the hypothalamus.
The anterior lobe is derived from the oral ectoderm and is composed of glandular epithelium.
The anterior pituitary synthesizes and secretes important endocrine hormones, such as ACTH, TSH, prolactin, growth hormone, endorphins, FSH, and LH.


The posterior lobe is connected to the hypothalamus via the infundibulum or pituitary stalk, giving rise to the tuberoinfundibular pathway.

The anterior pituitary is functionally linked to the hypothalamus via the hypophysial-portal vascular connection in the pituitary stalk.
These hormones are released from the anterior pituitary under the influence of hypothalamic hormones.
For example, uterine contractions stimulate the release of oxytocin from the posterior pituitary, which in turn increases uterine contractions.

The adenohypophysis, also referred to as the anterior pituitary is divided into anatomical regions known as the pars tuberalis and pars distalis.


Through this vascular connection the hypothalamus integrates stimulatory and inhibitory central and peripheral signals to the five phenotypically distinct pituitary cell types.
The hypothalamic hormones travel to the anterior lobe by way of a special capillary system, called the hypothalamic-hypophyseal portal system. In adult humans it is just a thin layer of cells between the anterior and posterior pituitary. The intermediate lobe produces melanocyte-stimulating hormone (MSH), although this function is often (imprecisely) attributed to the anterior pituitary.
