Pars tuberalis

From Wikipedia, the free encyclopedia

Pars tuberalis
Pituitary gland. (Most of the orange region is "pars distalis", but the part at the top is "pars tuberalis".)
Latin	pars tuberalis adenohypophyseos

The pars tuberalis is part of the anterior lobe of the pituitary gland, and wraps the pituitary stalk in a highly vascularized sheath.

[edit] Histology

Prinicipal cells of the pars tuberalis are low columnar in form, with the cytoplasm containing numerous lipid droplets, glycogen granules, and occasional colloid droplets. A sparse population of functional gonadotrophs are present(indicated by immunoreactivity for ACTH, FSH, and LH)^[1].
