Biology Question Bank for Entrance Exams

For AIPMT Main other Medical Entrance Exam Prepration, Question Bank for Biology Endocrine System is given below.

Animals maintain dynamic equilibrium amongst different physiological processes. Endrocrine glands play an important role in regulating various physiological processes, in contantly changing enviornment. ADH secretion either stops or decreases, when water amount in body increases. Hence concentration of urine decrease and surplus water of body is removed. When sugar in blood increases , immediately insulin will convert this surplus glucose into glycogen and minimum required glucose level of the blood is maintained. Endocrine glands are ductless gland, its secretion is poured in the blood. Endocrine gland are very sepcific vary greatly in their location, embryonic origin and functions.

Pituitary gland and pineal gland are found in head region. Thyroid gland is present in neck, Thymus gland is present in thoracic region, Adrenal gland and ovary are presnt in abdominal region. Testes are present outside body in scrotum (As development of sperm require comparatively less temperature, than normal body temperature).

The secretions of endocrine glands are different from each other in their chemical nature. Hormones of Pituitary, Pineal and cells of islet of Langerhans are chemically peptide or polypeptie and protien. Hormones of adrenal cortex are steroids. Epinephrin (Hormone of adrenal ) is derivative of amino acid. Hypothalamus regulate secretion of anterion pituitary gland through various releasing hormones (RH). Posterior pituitary lobes hormone are secreted by hypothalamus neurons directly Other than GH, every hormone of anterior pituitary strimulates some other gland of body to relase its homrone, Hence these hormones are called tropic hormone. GH directly act on the cells and tissues and regulates their growth. Pineal glands secretion mainly regulates 24 hours rhythm of body

Hormones of thyroid gland [Thyroxine, TCT] controls processes like carbohydrate metabolism. ATP synthesis and osteoblast. Hormones of parathyroid gland regulate Ca+2 level in blood. Thymus gland atrophies in adult, its hormone provide immunity to the body. they stimulate development and differentiation of T-lymphocytes. It also gives humoral immunity and stimulates antibody production.

The adrenal gland is presnet in abdominal region and it is divided in to two disnict regions; cortex and medulla. Hormones of cortex regulates carbohydrate metabolism and osmoregulation, Glucocorticoids of cortex region regulates carbohydrate metabolisum, mineralocorticoids of cortex region regulates level of water and mineral ions. Sexcorticoids of adrenal cortex enhances secondary sexual characters. Adrenal medulla secretion epinephrine and non-epinephrine, which are called catecholamine. All physiological changes, which arises in stress conditions are under the effect of these hormones. Cells of islet of langerhans make endocrine part of pancreas. Insulin and glucogon are secreted by endocrine part of pancreas and they regulate sugar level in blood.

Ovary and testes are endocrine glands. Ovary secretes Estrogen, progesterone and relaxin. Testes secretes androgens. Testosterone is the most potent hormone. These hormone regulates expression of secondary sexual characteristics. Other endrocrine gland, there are several non-endrocrine cells/ tissuse known to secrete certain secretions, which are known as growth factors. these growth factors have role in general growth and the process like regeneration. ANF (secreted by atrial wall of heart). Etrythropoietin (secreted by JGA), CCK, GIP (secreted by gastro-intestinal wall) are examples of growth factors. Precisely hormones are chemical messangers, which regulates growth and development by accelerating or inhibiting enzyme activity.
