Summary
The Pars Intermedia of male and female grass snake has been studied by light and electron microscopy. The general structure and histology of the grass snake intermediate lobe is described. Two main cell types are recognized.
The first, glandular cells, predominate in number and are characterized by the presence of electron — dense granules about 600 to 900 mμ in diameter; sometimes these cells are deprived of granules, and rough endoplasmic reticulum is well developed.
The second, stellate cells, are devoid of granules and show elongated processes inserted between the glandular cells.
A few nerve fibres and axon terminals containing dense granules and electron lucent vesicles are observable.
