Medical Definition of Pars infundibularis

1. The upward extension of the anterior lobe that wraps around the infundibular stalk; its cells, mostly gonadotropic, are arranged in cords and clusters; it is supplied by the superior hypophyseal arteries and contains the first capillary bed and the venules of a portal system that carries neurosecretory factors from the hypothalamus to a second capillary bed in the adenohypophysis where they regulate the release of hormones. See: hypophysis. Synonym: infundibular part, pars infundibularis. (05 Mar 2000)
