| Calotes versicolor, collected during peak breeding and nonbreeding season were used for the study of anatomy and histophysiology of pituitary gland. In C. versicolor the pituitary gland is small compact mass attached to the hypothalamus by a delicate stalk. It is of two basic units, adenohypophysis and neurohypophysis. The adenohypophysis includes pars distalis (PD) and pars intermedia (PI). The pars tuberalis (PT) which is usually reduced in reptiles, is absent in C. versicolor. The neurohypophysis is composed of median eminence (MI) and neural lobe or pars nervosa (PN). The anterior PD is rich acidophils than the posterior PD during breeding season. These cells are differentiated as A1 and A2 cells. The A1 cells are erythrosinophilic and stained purple... |
