Explanation:
The suprarenal(adrenal) glands are an important pair of endocrine glands situated on the upper poles of the kidneys and enclosed in the same fascial sheath as that of kidneys (renal fascia).
Each gland consists of two parts:
(a) a relatively thick outer cortex which develops from the mesoderm (mesodermal lining of the peritoneal cavity) and
(b) a central medulla which develops from the neural crest and is equivalent to a group of sympathetic ganglion cells.
The medulla is composed of large granular chromaffin cells which secrete adrenaline and noradrenaline (catecholamines).
The pituitary gland is a small endocrine gland situated in the hypophyseal fossa on the superior surface of the body of the sphenoid (sella turcica). It is suspended from the floor of the 3rd ventricle of the brain by a narrow stalk called infundibulum. The gland is enclosed in the dural sheath, whose tense upper wall—the diaphragma sellae—is perforated by the infundibulum or stalk. On each side, the pituitary gland is related to the cavernous sinus and in front and behind to the anterior and posterior intercavernous sinuses. Pars anterior secretes growth hormone and prolactin
The ovaries are female gonads (homologous of testes in the male) which produce female gametes called oocytes (ripe ova). The ovaries are almond-shaped and grayish pink in colour. Each ovary is about 4 cm long, 2 cm wide and 1 cm thick.The ovaries produce two hormones—progesterone and estrogen. The progesterone is secreted by the luteal cells and estrogen by the follicular cells.
