Pars intermedia
The interface of pars nervosa and pars intermedia shows remnants of Rathke’s pouch. In this section, the colloid of the cysts was lost in tissue processing. Basophils of the pars intermedia, lying adjacent to the cysts, are adrenocorticotropes. Visible in the pars nervosa are thin, unmyelinated hypothalamic axons, which end in variously-sized Herring bodies. 1000x
