Investigation on the pars tuberalis of the hypophysis of Psammodromus algirus L. (Sauria). An electron microscopy study.

The anatomic-microscopic and cytological aspects of the lateral lobes of adenohypophysis of Psammodromus algirus have been studied. Along the whole of its extension, the 'pars tuberalis' appears to be separated from the hypothalamic region by a space of 1600 A with a winding course filled with fibrillar matrix. The main inclusions of 'pars tuberalis' cells are glycogen granules histochemically characterized by the Thiery's method. A correlation between the electron and light microscopy observations on the lateral lobes of Psammodromus algirus is attempted.
