By chemical nature, hormones are never :

A
steroids

B
amino acid derivatives

C
proteins

Hormones are generally proteincomponents having amino acids as well as steroids. Hormones are generally not monosaccharide derivatives in nature
Question 5
4 / -1

Following conversion in forward and backward direction is regulated as :
Blood calcium Bone calcium

A
(i) is PTH and (ii) is TCT

Glucocorticoids regulate metabolism of carbohydrates, lipids andprotein. This hormone is released from adrenal gland.
Question 8
4 / -1

Shekhar is 3 years old and he lives in hilly areas. He has swollen neck :

i. He is suffering from goitre caused due to iodine deficiency which may lead to cretinism.
ii. Goitre may lead him to myxoedema and Grave’s disease in future.

A
both are correct.

B
Statement ii) is wrong and i) is correct.

C
both are wrong.

D
Statement ii) is correct and i) is wrong.

Solution

The persons living in hilly areas generally suffer from goiter disease. Goiter is caused due to iodine deficiency which may leads to cretinism. Goiternever leads to myxedemaor hypothyroidism.
Question 9
4 / -1

To exert their effect on the target cell, water soluble hormones will need to bind with

A
nuclear receptors.

B
plasma proteins.

C
cytosolic receptors.

D
cell membrane bound receptors.

Solution

Water- soluble hormones include glycoproteins, catecholamines and peptide hormones composed of polypeptides e.g. thyroid- stimulating hormone, follicle- stimulating hormone, luteinizing hormone and insulin.
These molecules are not lipid- soluble and therefore they are not able to diffuse through cell membranes so they bind with the cell membrane bound receptors.
Question 10
4 / -1

The hormone secreted by pars intermedia of hypophysis is :

A
GH

B
ACTH

C
MSH

D
TSH

Solution

The hormone secreted by pars intemedia of hypophysis is melanocyte-stimulating hormones (MSH).MSH is a peptide hormone also knownas melanotropins.
Question 11
4 / -1

A chemical acts slowly, requiring hours to take effect. It may pass in and out of many cells in which they have no effect. When they find appropriate receptor in their target cell they bind to it. Chemical is :

A
adrenaline

B
somatotropin

C
oxytocin

D
aldosterone

Solution

Correct Answer :- d
Explanation : Aldosterone is a chemical acts slowly, requiring hours to take effect. It may pass in and out of many cells in which they have no effect.
Its main role is to regulate salt and water in the body, thus having an effect on blood pressure.
Question 12
4 / -1

Secretion of aldosterone is stimulated by :

i. decrease in sodium ion concentration in the plasma.
ii. decrease in potassium ion concentration in the plasma.
iii. decrease in the volume of blood.

A
only ii) and iii) are correct.

B
onlyi) and ii) are correct.

C
only i) and iii) are correct.

D
all are correct.

Solution

Secretion of aldosterone is stimulated by decrease in sodium ion concentration in theplasma. Aldosterone secretion also decrease the volume of blood due to more absorption of water during filtration in kidney.
Question 13
4 / -1

Adrenal medulla consists of a cluster of _____ nerves and those cells are also known as _____ cells :

A
sympathetic , paraffin

B
sympathetic , chromaffin

C
parasympathetic , follicular

D
parasympathetic , clear

Solution

Adrenal medulla consists of a cluster of sympathetic nerves and those cells are also known as chromaffin cells. Adrenal medulla is part of the adrenal gland located at the center of the adrenal gland.

ii. It’s outer region secretes steroid hormones.
iii. Also known as gland of emergency.

A
only i) and iii) are correct.

B
only ii) and iii) are correct.

C
only i) is correct.

Solution

Suprarenal glands represents two endocrine glands arranged in one organ. It outer region secretes steroid hormones. It is also known as gland of emergency.
Question 16
4 / -1

Process of parturition is facilitated by :

A
Gonadotropins

B
Oxytocin

C
Relaxin

D
both B & C

Solution

The process of parturition begins after completion of gestation period. The muscles present in uterus start contracting due to release of hormone relaxin and Oxytocin.
Question 17
4 / -1

A dwarf person showing stunted growth and mental retardation both, is a result of hyposecretion of

A
Parathyroid hormone

B
Growth hormone

C
Thyroid hormone

D
Thymosin and melatonin

Solution

Hypothyroidism causes defective development and maturation of the growing baby leading to stunted growth (cretinism), mental retardation, low intelligence quotient, abnormal skin, deaf-mutism, etc.

4 / -1

The largest endocrine gland is

A
Testis

B
Pituitary

C
Pancreas

D
Thyroid

Solution

Thyroid is the largest endocrine gland present in human body. This gland release thyroxin hormone that help in metabolism of carbohydrates, fats and proteins.

B
a)-i, b)-ii, c)-iv, d)-iii

C
a)-ii, b)-i, c)-iii, d)-iv

D
a)-ii, b)-i, c)-iv, d)-iii

Solution

The atrial wall of our heart secretes a very important peptide hormone called ANF. The juxtaglomerular cells of kidney produce a peptide hormone called erythropoietin. The gastro-intestinal tract secrete peptide hormone called CCK
Question 20
4 / -1

A person accidentally got his adrenal gland injured. He died & reports will probably reveal that death was caused due to :

A
loss of adrenal cortex function

B
loss of both

C
loss of adrenal medulla function

D
Insulin shock

Solution

Adrenal cortex is situated along the perimeter of the adrenal gland. The adrenal cortex mediates the stress response through production of aldosterone and cortisol. If a person got injured his adrenal gland may die due to loss of stress responsewhich will be reveled in report.
