Pars intermedia
The pars intermedia of the adenohypophysis lies adjacent to the pars nervosa and to the colloid-filled, cystic remnants of Rathke’s pouch. Cells of this subdivision also migrate into the pars nervosa. The pars intermedia, which is rudimentary in humans, is composed exclusively of basophils. 200x
