1.The neural system and the endocrine system jointly coordinate and regulate the physiological functions in the body. 2.The endocrine glands and hormone producing diffused cells/tissues located in different parts of our body constitute the endocrine system. 3.Neurohypophysis also known as posterior pituitary,stores and releases two hormones called oxytocin and vasopressin. 4.TSH stimulates the synthesis and secretion of thyroid hormones from the thyroid gland. 5.The thyroid gland is composed of two lobes which are located on eitcher side of the trachea. 6.Thyroid hormones play an important role in the regulation of the basal metabolic rate. 7.The secretion of PTH is regulated by the circulating levels of calcium ions. 8.Thymosins play a major role in the differentiation of T lymphocytes,which provide cell-mediated immunity. 9.The centrally located tissue in adrenal gland is called the adrenal medulla,and outside this lies the adrenal cortex. 10.The adrenal medulla secretes two hormones called adrenaline or epinephrine and noradrena-line or norepinephrine. 11.Adrenal medullary hormones increase alertness,pupilary dilation ,piloerection,sweating. 12.Corticoids, which are involved in carbohydrate metabolism are called glucocorticoids. 13.Cortisol is involved in maintaining the cardiovascular system as well as the kidney functions. 14.Pancreas is a composite gland which acts as both exocrine and endocrine gland. 15.Glucose homeostasis in blood maintained jointly by the two-insulin and glucagons. 16.Androgens regulate the development,maturation and functions of the male accessory sex organs like epididymis,vas deferens,seminal vesicles,prostate gland,urethra. 17.Females have a pair of ovaries located in the abdomen. 18.Progesterone also acts on the mammary glands and stimulates the formation of alveoli and milk secretion. 19.Hormones produce their effects on target tissues by binding to specific proteins called hormone receptors. 20.Target tissue metabolism and physiological functions are regulated by hormones. 21.Hormones regulate metabolism,growth and development of our organs,the endocrine glands or certain cells. 22.Parathyroid glands secrete parathyroid hormone (PTH) which increases the blood ca2+ levels and plays a major role in calcium homeostasis. 23.The ovary secretes estrogen and progesterone. 24.Gastrointestinal tract secretes gastrin,secretin,cholecystokinin and gastric inhibitory peptide. 25.Hormones regulate the secretion of digestive juices and help in digestion.
