See also: pituitary gland.

adenohypophysis

/ad·e·no·hy·poph·y·sis/ (-hi-pof´ĭ-sis) the anterior (glandular) lobe of the pituitary gland; it secretes the anterior pituitary hormones such as growth hormone, thyrotropin, and others.adenohypophys´eal

adenohypophysis

(ăd′n-ō-hī-pŏf′ĭ-sĭs)
n.
The anterior glandular lobe of the pituitary gland that secretes many hormones, including ACTH, prolactin, and somatotropin.

adenohypophysis

[ad′ənō′hīpof′isis]
Etymology: Gk, aden + hypo, beneath, phyein, to grow
the anterior lobe of the pituitary gland. It secretes growth hormone, thyroid-stimulating hormone, adrenocorticotropic hormone, melanocyte-stimulating hormone, follicle-stimulating hormone, luteinizing hormone, prolactin, beta lipotropin molecules, and endorphins. The release of hormones from the hypothalamus regulates these secretions. Also called anterior pituitary.

adenohypophysis

The anterior glandular lobe of the pituitary, which secretes FSH, LH, ACTH, TSH, GH, and prolactin in response to releasing hormones produced by the hypothalamus.

ad·e·no·hy·poph·y·sis

(ad'ĕ-nō-hī-pof'i-sis) [TA]
The anterior pituitary gland. It consists of the distal part, intermediate part, and infundibular part.
See also: hypophysis
Synonym(s): lobus anterior hypophyseos [TA] , anterior lobe of hypophysis.

adenohypophysis

The front lobe of the PITUITARY GLAND. This is structurally and functionally distinguishable from the rear lobe (posterior pituitary).

adenohypophysis

that part of the PITUITARY GLAND derived embryologically from the HYPOPHYSIS.

ad·e·no·hy·poph·y·sis

(ad'ĕ-nō-hī-pof'i-sis) [TA]
The anterior pituitary gland; it consists of the distal, intermediate, and infundibular parts.

adenohypophysis

the so-called anterior lobe of the hypophysis cerebri (see also pituitary), which in domestic animals mostly surrounds the posterior lobe. It develops from the roof of the embryonic mouth and is divided into a large pars distalis, a smaller pars tuberalis and a pars intermedia. It secretes hormones under the control of releasing agents which arrive from the hypothalamus via a hypothalamohypophyseal portal system. The hormones include growth hormone, ACTH, beta-lipotropin, prolactin, thyrotropic hormone, follicle-stimulating hormone and luteinizing hormone.

38,39) The normal adenohypophysis is composed of acini with a well-developed reticulin fiber network; hyperplasia results in expanded acini that preserve their reticulin, whereas adenomas exhibit total breakdown of the reticulin pattern.
As shown in Figure 2, C, Bcl-2 immunostaining of the normal pituitary gland is focal, and some authors (4) have suggested that it is primarily restricted to folliculostellate cells of the adenohypophysis.
Releasing and inhibiting factors produced in the neurons in the hypothalamus are transported to the adenohypophysis via the tuberhypophyseal neural tract and the hypophyseal portal system.

In nonneural tissues, it is distributed widely in definite cell types, including melanocytes, Langerhans cells, chondrocytes, folliculostellate cells of the adenohypophysis, adrenal gland satellite cells, Leydig cells, and interdigitating reticulum cells (27), whereas adipose tissue constitutes a site of concentration for the protein comparable to the nervous tissue (33).
