 The Normal Pituitary

Figure 1-15 Figure 1-16 POSTERIOR LOBE OF THE PITUITARY HISTOLOGY OF THE NORMAL PITUITARY By electron microscopy, a pituicyte (a glial cell of the Hematoxylin and cosin staining shows acini of adenohypo- posterior lobe) is seen within neuronal processes containing _physial cells. Some cells are acidophilic, others are chromo- neurosecretory granules, including a markedly dilated nerve __ phobic. Basophils contain clear vacuoles, corresponding to the ending known as a “Herring body.” “enigmatic body” of corticotrophs.

‘The Mann stain readily distin- guishes bright red acidophils, blue baso- phils (many with “enigmatic bodies”), and a large number of chromophobes.
