Question 1
1 / -0

Which of the following is least likely to result in the release of epinephrine (adrenaline) from the adrenal glands?

A
Competing in an athletic event

B
First day of college after X

C
Falling asleep during a lecture

D
Taking a test while unprepared

Solution

Epinephrine is normally produced by both the adrenal glands and certain neurons. It plays an important role in the fight-or-flight response by increasing blood flow to muscles, the output of the heart, pupil dilation, and blood sugar. Every emotional response has a behavioral component, an autonomic component and a hormonal component. The hormonal component includes the release of epinephrine, an adrenomedullary response that occurs in response to stress and that is controlled by the sympathetic nervous system. The major emotion studied in relation to epinephrine is fear.
Therefore, the correct answer is option C.
Question 2
1 / -0

The function of pineal body is to

A
Lighten the skin colour

B
Control sexual behavior

C
Regulate the period of puberty

D
All of the above

Solution

the pineal body is a small endocrine gland in the vertebrate brain. It controls the sex drive, hunger, thirst, the biological clock and regulates the period of puberty. It secretes melanin, which is responsible for pigmentation of the skin.
Question 3
1 / -0

When testosterone levels are low, which hormone is released?

A
Stimulating Hormone

B
Progesterone

C
Luteinizing Hormone

D
Vasopressin
Solution
- The pituitary gland controls the level of testosterone in the body. When the testosterone level is low, the pituitary gland releases a hormone called as luteinizing hormone (LH).
- This hormone stimulates the testicles to make more testosterone.
Therefore, the correct answer is option C.
Question 4
1 / -0

Release of adrenaline results in the supply of

A
Nitrogen and glucose

B
Carbon and oxygen

C
Oxygen and glucose

D
Carbon and nitrogen

Solution

When adrenaline is released into the bloodstream, the hormone boosts the supply of oxygen and glucose to the brain and muscles, while suppressing other non-emergency bodily processes (digestion in particular). With dilated blood vessels and air passages, the body is able to pass more blood to the muscles and get more oxygen into the lungs, thereby increasing physical performance for short bursts of time.
Therefore, the correct answer is option C.
Question 5
1 / -0

The pituitary gland by virtue of its tropic hormones controls the secretory activity of other endocrine glands. Which one of the following endocrine glands can function independently of the pituitary gland?

A
Thyroid

B
Gonads

C
Adrenal

D
Parathyroid

Solution

The parathyroid glands are four tiny glands, located in the neck, each gland is about the size of a grain of rice. Parathyroid gland secretes parathormone hormone, which regulates $$Ca^{++}$$ and phosphate ion in the body. This gland works independently to the pituitary gland.
The pituitary gland, on the other hand, is the major endocrine gland, a pea-sized body attached to the base of the brain that is important in controlling growth and development and the functioning of the other endocrine glands, which includes thyroid, gonads and adrenals etc.
Therefore, the correct answer is option D.
Question 6

Adrenal gland located above kidneys produces

A
F

B
E

C
C

D
D

Solution

The endocrine system is composed of several endocrine glands. A ductless gland or endocrine gland secretes its product, i.e., hormones directly into the bloodstream and shows its effects at distinct part of the body. Adrenal gland located above kidneys produces adrenalin.

Pituitary gland also known as master gland is located at the base of the brain and it produces

A
A

B
B

C

Solution

The endocrine system is composed of several endocrine glands. A ductless gland or endocrine gland secretes its product, i.e., hormones directly into the bloodstream and shows its effects at distinct part of the body. The pituitary gland also known as master gland is located at the base of the brain and it produces growth hormone.

Thyroid gland located in neck region produces

A
F

B
C

C
B

D
D

Solution

The endocrine system is composed of several endocrine glands. A ductless gland or endocrine gland secretes its product, i.e., hormones directly into the bloodstream and shows its effects at distinct part of the body. Thyroid gland located in neck region produces thyroxine.
So, the correct answer is 'B'
Question 9
1 / -0

Which of the following hormones regulate solute reabsorption during urine formation in rabbit?

A
Angiotensin III and Angiotensin I

B
Nor-epinephrin and Epinephrin

C
Angiotensin II and Aldosterone

D
Antidkaretic hormone and Angiotensin I

Solution

Rabbits are herbivores and thus the urine is normally alkaline (pH 8-9) and turbid. The regulatory activities of kidneys lead to the formation of urine as a by-product. Urine formation involves three main steps—the glomerular filtration, the tubular reabsorption, and the tubular secretion. To keep the sodium and water balance in check, the angiotensin and aldosterone system helps. The inactive angiotensinogen is converted to angiotensin I which is then converted to angiotensin II. This along with aldosterone helps in maintaining the required amount of sodium and water along with re-absorption of salts.
Question 10
1 / -0

Erythropoietin is a hormone produced from

A
Thymus

B
Pituitary

C
Heart

D
Kidney

Solution

Erythropoietin is a protein hormone produced by the kidney. After being released into the blood stream it binds with receptors in the bone marrow, where it stimulates the production of red blood cells (erythrocytes).
