Abstract:
The brain, a power centre of any living multicellular organism comprises several structural components as to cerebrum, cerebellum, optic lobe and medulla oblongata is observed along with the accommodating attire of some endocrine glands and the pituitary gland is one of them. It exerts influence over the functions of many other endocrine glands including control of body temperature and while maintaining the homeostasis it harmonizes with environmental factors after heat fluctuations of the body.The gross anatomical brain is observed in Kadaknath (Gallus gallus domesticus) birds. The surface texture was creamy pinkish colored. It had meninges from outward to inwards viz. duramater, arachnoid and piamater. The menengial coverings on brain in Kadaknath were black in color. The olfactory tracts were not observed. Gross anatomical in-vitro disquisition on pituitary glands showed a tiny pituitary gland, also known as hypophysis cerebri. It was observed at the posterior of optic chiasm. The pituitary gland observed lying into the porous bony cavity called sella turcica of the sphe­noid bone. Pituitary gland was the rounded disc which observed convex at dorsal and somewhat concave at its ventral side.
