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 ==
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)<ref>Ross, Michael. Histology: A Text and Atlas. 5th ed., 2006. pp 695</ref>.
