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

Histology

Principal 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, Follicle-stimulating hormone, FSH, and Lutenizing Hormone, LH).Ross, Michael.
