1. Posterior pituitary release oxytocin and vasopressin hormones.

2. Aldosterone is an example of mineralocorticoid and it is released adrenal cortex from region of endocrine gland.

3. Grave's disease is caused by hyper-secretion of thyroxine.

4. In diabetes mellitus blood glucose is high. The hormone which is produced in less quantity is insulin.

5. Parathyroid hormone increases blood Ca level while Calcitonin decreases it.

Revision Worksheet-2

List the various diseases caused by :

a. Over production of thyroxine - Grave's disease, exophthalmic goitre

b. Under production of thyroxine - Cretinism in children; myxoedema in adults

c. Low insulin - Diabetes mellitus

d. Low ADH - Diabetes insipidus

e. Low GH - Dwarfism

f. Excessive GH (in adults) - Acromegaly

Extra :

1. $\textbf{Aldosterone}$ acts mainly at the renal tubules and stimulates the reabsorption of $\sf{Na^+}$ and water and excretion of $\sf{K^+}$ and phosphate ions.

2. $\textbf{Melatonin}$ reduces quantity of FSH and LH and acts as anti-gonadotrophic hormone.

3. $\textbf{Oxytocin}$ stimulates secretion of milk from mammary glands; causes contraction of uterus at the time of childbirth.

4. $\textbf{Testosterone}$ affects the normal development and functions of secondary sexual organs and characters in male and stimulates formation of sperms.

5. $\textbf{Vasopressin}$, also known as Antidiuretic hormone or ADH, stimulates the reference for reabsorption of water and stimulates contraction of smooth muscles, blood vessels and causes rise in blood pressure.
