Ovary is the primary female sex organs that produces the female gamete (ovum) andseveral steriod hormones (ovarian hormones). The two steriod hormones produced byovary are oestrogen and progesterone. oestrogens produces wide ranging actions such asstimulation of growth and activities of female secondry sex organs, development ofgrowing ovarian follicles, appearance of female secondry sex characters (e.g., high pitchof voice, etc) mammary gland development. Oestrogens also regulate female sexualbehaviour.
Alpha cells od islets of Langerhans of the endocrine pancrease secrete a hormone calledglucagon. It is a peptide hormone and plays an important role in maintaining the normalblood glucose levels. It acts mainly on the liver cells and stimulates glycogenolysisresulting in an increased blood sugar. In addition, this hormone stimulates the process ofgluconeogenesis which also contributes to hyperglycemia. Glucagon reduces the cellularglucose uptake and utilization. Thus, glucagon is a hyperglycrmic hormone.
The pars distalis regions of pituitary, commony called produced anterior pitutary, GrowthHormone (GH), prolactin (PRL), Thyroid Srimulating Hormone (TSH), adrenocorticotrophichormone (ACTH), Luteinizing hormone (LH) and follicle stimulating hormones(FSH). Over secretion of GH stimulates abnormal growth of the body leading togigantism and low secretion of GH results in stunted growth resulting in pitutarydwarfism.
