Chemical Coordination and Integration - II (Class XI)

MSH or Melanocyte stimulating hormone is the hormone made up of long chain peptides and targets the melanocyte cells present in the skin.

It is caused due to the excess secretion of thyroxine or hyperthyroidism.

It is an autoimmune disease caused due to sensitisation of thyroglobulin.

MSH or Melanocyte stimulating hormone is the hormone made up of long chain peptides and is secreted by the intermediate lobe of pituitary.

The major hormonal secretion of the parathyroid gland is known as parathormone or Collip's hormone.

Thymus is known as the training school of T-lymphocytes and is responsible for the proliferation and maturation of T-lymphocytes.

It is stimulated by the sympathetic nervous system for meeting an emergency.

Oversecretion of aldosterone due to adrenal cortical tumour in the region of zona glomerulosa results in Conn's syndrome.

It is released by the delta cells of the islets of Langerhans and keeps a check on the excessive secretion of the alpha and beta cells.

It is the phenomenon of hyposecretion of PTH by parathyroid due to autoimmune disease, genetic disease or accidental damage to the glands. It leads to hypercalcemic or parathyroid tetany.

It is a double gland fitted over the upper ends of kidneys and has two parts, namely adrenal cortex (mesodermal origin) and adrenal medulla (ectodermal origin). These parts are functionally unrelated.

hCG (Human chorionic gonadotropin) stimulates progesterone release from the corpus luteum and maintains it.

Atrial natriuretic factor is the hormone secreted by heart. It helps in maintaining blood volume and reducing blood pressure.

It is an intestinal hormone that stimulates secretion of mucus from Brunner's gland.

It is an endocrine gland of mesodermal origin and helps in maintenance of corpus luteum and the continued secretion of progesterone.

It is secreted by the adrenal gland and its target tissue is kidney.

It is caused due to deficiency of thyroxine and is characterised by puffy appearance caused by waxy swelling of skin due to abnormal deposition of glycosaminoglycans in the skin and other tissues.

It is a mineralocorticoid secreted by the zona glomerulosa of adrenal cortex. It is the main mineralocorticoid of human body.

Cholecystokinin is produced by duodenum in response to the presence of food. It causes contraction of gall bladder for releasing bile.

Corpora arenacea (or brain sand) are calcified structures in the pineal gland.
