(ii) Myxoedema

(iii) Gigantism

(iv) Exophthalmic goitre

Answer :

(i) insulin,

(ii) Hyposecretions Thyroxine

(iii) Somatotropic Growth Hormones

(iv) Hypersecretion of  Thyroxine

Question 2. Name the hormone responsible for the following functions

(i) Converting glycogen to glucose

(ii) Regulates basal metabolism

(iii) Ossification of bones

(iv) Prepares the body during emergency

(v) Responsible for normal growth of the whole body

Answer :

(i) glucagon

(ii) Thyroxine

(iii)  Parathyroid hormone

(iv) Adrenaline hormone

(v) growth hormone

Question 3. Study the diagram given below and then answer the questions that follow :

Question 3. Study the diagram given below and then answer the questions that follow :

(i) Name the cells of the pancreas that produce (1) glucagon (2) insulin.

(ii) State the main function of (1) glucagon (2) insulin.

(iii) Why is the pancreas referred to as an exo-endocrine gland ?

(iv) Why is insulin not given orally but is injected into the body ?

(v) What is the technical term for the cells of the pancreas that produce endocrine hormones ?

(vi) Where in the body is the pancreas located ?

Answer :

(i) (1) Glucagon—Produced in alpha cells of pancreas.
(2) Insulin—Produced in beta cells of pancreas.

(ii) (1) Glucagon—It helps to convert glycogen to glucose when blood glucose level falls.
(2) Insulin—It helps to convert excess glucose to glycogen when there is higher level of glucose in blood.

(iii) It is both exocrine as well as endocrine gland. As exocrine, it secretes pancreatic juice containing digestive enzymes and pour them into duodenum part of intestine through pancreatic duet. As endocrine, it secretes hormones like insulin, glucagon and somatostatin and pour them directly into blood.

(iv) Insulin is a protein by composition so if it is given orally it will get digested in the stomach and will not be able to perform its function.

(v) Islets of Langerhans.

(vi) In the abdomen in the loop of small intestine close to duodenum part of small intestine.
