Abstract

The pituitary gland of Anchoviella lepidentostole consists of the neurohypophysis and the adenohypophysis, which is subdivided in pars intermedia and pars distalis. The pars distalis comprises pars distalis rostralis and pars distalis proximalis. The cell types of the pars distalis rostralis are arranged in follicles. In the follicular epithelium, four cell types were cytochemically characterized: l-PDR (basophilic), ll-PDR (lead haematoxylin+/HPb+), lll-PDR (PAS+, AB pH2.5+ and AF+), IV-PDR (acidophilic). Thepars distalis proximalis has two cell types: l-PDP (PAS+, AB pH 2.5+ and AF+) and ll-PDP (acidophilic). In the pars intermedia there are two cell types: l-PI (HPb+) and ll-PI (chromophobes).
