It is based upon the gross anatomical separation of the posterior and anterior pituitary along the cystic remnants of Rathke's pouch, causing the pars intermedia to remain attached to the neurohypophysis.
14.
Without regulation from dopamine, the pars intermedia develops hyperplasia and adenoma formation, leading to gross enlargement and excessive production of POMC . These adenomas also have the potential to compress the hypothalamus and optic chiasm.

However, a veterinary form of pergolide, marketed under the trade name Prascend, is permitted for the treatment of pituitary pars intermedia dysfunction ( PPID ) also known as equine Cushing's syndrome ( ECS ) in horses.
16.
The pituitary gland is divided into two lobes, the anterior lobe ( which accounts for two thirds of the volume of the gland ), and the posterior lobe ( one third of the volume ) separated by the pars intermedia.

Endocrinopathy is usually the result of improper insulin regulation, and is most commonly seen with pituitary pars intermedia dysfunction ( also called equine Cushing's syndrome ) and equine metabolic syndrome ( EMS ), as well as obesity and glucocorticoid administration.

Their posterior ends are expanded and are in contact with the greater vestibular glands; their anterior ends are tapered and joined to one another by the pars intermedia; their deep surfaces are in contact with the inferior fascia of the urogenital diaphragm; superficially they are covered by the bulbospongiosus.

The vestibular bulbs are homologous to the bulb of penis and adjoining part of the corpus spongiosum of the male, and consist of two elongated masses of erectile tissue, placed one on either side of the vaginal orifice and united to each other in front by a narrow median band termed the " pars intermedia ".
