Name the following:

(a) The three hormones produced by the pancreas.

(b) The hormone produced by the adrenal medulla.

(c) The condition caused by the oversecretion of insulin.

(d) The hormone secreted by(beta) cells of the islets of Langerhans.

(e) The hormone which increases blood pressure.

(f) The hormone causing more urine formation.

(g) The hormone which stimulates the entire sympathetic nervous system.

(a) Insulin, glucagon, somatostatin.

Explanation: Insulin is secreted by beta cells, glucagon by alpha cells and somatostatin by delta cells of Islets of Langerhans of the pancreas.

(b) Adrenaline

Explanation: Adrenaline is secreted by adrenal medulla which is an emergency hormone that prepares the body to fight or flight from the emergency situation.

(c) Insulin shock

Explanation: Due to oversecretion of insulin by pancreas the level of sugar in the blood becomes very low and the patient may become unconscious and this condition is called insulin shock.

(d) Insulin

Explanation: Pancreas has special hormone-secreting cells called Islets of Langerhans and beta cells secrete insulin which checks sugar level in the blood.

(e) Adrenaline

Explanation: Adrenaline is secreted during emergency situation which increases heartbeat accompanied by an increase in blood pressure.

(f) ADH/Vasopressin

Explanation: ADH increases reabsorption of water from kidney tubules and deficiency of this hormone causes diabetes insipidus where the patient feels frequent urination.

(g) Adrenaline

Explanation: Adrenaline is secreted under stress condition like anger, emotional stress or fear which stimulates sympathetic nervous system, as a result, our heart beat faster, blood pressure increases, breathing rate increases etc.
