    en.wikipedia.org/wiki/Anterior_pituitary

    The anterior pituitary (also called the adenohypophysis or pars anterior) is a major organ of the endocrine system.The anterior pituitary is the glandular, anterior lobe that together with the (posterior pituitary, or the neurohypophysis) makes up the pituitary gland (hypophysis) which, in humans, is located at the base of the brain, protruding off the bottom of the hypothalamus.

  3. Pituitary gland - Wikipedia

    en.wikipedia.org/wiki/Pituitary_gland

    The pituitary gland or hypophysis is an endocrine gland in vertebrates. In humans, the pituitary gland is located at the base of the brain, protruding off the bottom of the hypothalamus. The human pituitary gland is oval shaped, about 1 cm in diameter, 0.5–1 gram (0.018–0.035 oz) in weight on average, and about the size of a kidney bean. [2 ...

  4. Hypophyseal portal system - Wikipedia

    en.wikipedia.org/wiki/Hypophyseal_portal_system

    The cells of the anterior pituitary express specific G protein-coupled receptors that bind to the neuropeptides, activating intracellular second messenger cascades that produce the release of anterior pituitary hormones. [4] The following is a list of hormones that rely on the hypophyseal portal system to indirectly mediate their function by ...

    en.wikipedia.org/wiki/Endocrine_gland

    The pituitary gland hangs from the base of the brain by the pituitary stalk, and is enclosed by bone.It consists of a hormone-producing glandular portion of the anterior pituitary and a neural portion of the posterior pituitary, which is an extension of the hypothalamus.

  7. Middle cranial fossa - Wikipedia

    en.wikipedia.org/wiki/Middle_cranial_fossa

    Behind the optic foramen the anterior clinoid process is directed backward and medialward and gives attachment to the cerebellar tentorium . Behind the tuberculum sellae is a deep depression, the sella turcica, containing the fossa hypophyseos, which lodges the pituitary gland, and presents on its anterior wall the middle clinoid processes.

  8. Hypopituitarism - Wikipedia

    en.wikipedia.org/wiki/Hypopituitarism

    The pituitary gland is located at the base of the brain, and intimately connected with the hypothalamus. It consists of two lobes: the posterior pituitary, which consists of nervous tissue branching out of the hypothalamus, and the anterior pituitary, which consists of hormone-producing epithelium.

  9. Pars intermedia - Wikipedia

    en.wikipedia.org/wiki/Pars_intermedia

    The pars intermedia is one of the three parts of the anterior pituitary. It is a section of tissue sometimes called a middle or intermediate lobe, between the pars distalis, and the posterior pituitary. [1] It is a small region that is largely without blood supply. [2] The cells in the pars intermedia are large and pale.
