NEXT : Herring bodies in the neurohypophysis of a dog.

Description:

This section contains the pars distalis, the pars intermedia, reamins of Rathke's pouch, and the pars nervosa. The pars distalis contains a variety of cells that vary in their staining property. There are acidophils, basophils and chromophobes. However, in a low powered micrograph of a H&E stained section like this one, the differences between the acidophils and basophils may not be that obvious. The par intermedia usually contains less diversed cells types with melanotropes most abundant, but there is quite a bit of species variations. The pars nervosa is made up of supportive cells (pituicytes) and unmyelinated nerve fibers (from the hypothalamus). Herring bodies, accumulated neurosecretory material, cannot be seen at this magnification. Original mag. 14x H&E Pituitary. Endocrine System. Dog.
