Weekly Quiz Competition

Question 1
1 / -0

Which hormone is secreted from zona glomerulosa ______________.

A
Aldosterone

B
Cortisol

C
Androgen

D
Glucagon

Solution

The zona glomerulosa which is a part of the adrenal gland is principally responsible for the secretion of aldosterone, under the regulation of the renin-angiotensin system. Aldosterone causes an increase in salt and water reabsorption into the bloodstream from the kidney thereby increasing the blood volume, restoring salt levels and blood pressure.
So, the correct option is 'Aldosterone'.
Question 2
1 / -0

All of the following pass through ampulla of vater, except

A
Eripsin

B
Amylopsin

C
Procarboxypeptidase

D
Sodium taurocholate

Solution

Ampulla of Vater is also called as the hepatopancreatic ampulla or the hepatopancreatic duct. It is formed by joining of pancreatic duct and the common bile duct. Sodium taurocholate is present in the bile salt. Through bile duct, it passes through ampulla of vater. Amylopsin is present in the pancreatic juice. Through pancreatic duct, it passes through the ampulla of vater. Procarboxypeptidase is secreted by the pancreas. It also passes through the ampulla of vater. Eripsin is present in the intestinal juice.
Thus, the correct answer is 'Eripsin.'
Question 3
1 / -0

If thymectomy is done during adult hood then what possibility is there?

A
Immunosuppresant

B
Die immediately

C
No advice reaction

D
Myasthenia gravis

Solution

The thymus gland plays an important role in the immune function of the body by acting as an reservoir for T cells. Thymectomy or removal of the thymus gland in new born does not show any effect. However, the removal of the thymus gland during adulthood will result in suppression of the immune system.
So, the correct option is 'Immunosuppresant'.
Question 4
1 / -0

Which one of the following is the primary female sex hormone?

A
Insulin

B
Adrenaline

C
Estrogen

D
Thyroxine

E
Calcitonin

Solution

Estrogen is a primary sex hormone in females responsible for the development and regulation of the female reproductive system and secondary sexual characteristics.
So, the correct answer is option C.
Question 5
1 / -0

All are the function of PTH except ______________________.

A
PTH simulates bone reabsorption /dilution /demineralization

B
PTH retards osteoclastic action

C
PTH increases $$Ca^{+2}$$ abosorption from the digestive tube

D
PTH stimulates reabsorption of $$Ca^{+2}$$ by the renal tubules

Solution

The hormone released by the parathyroid glands is called the parathyroid hormone (PTH). It is also called parathyrin. This hormone is involved in the formation or mineralization of bones. It is released when the levels of calcium ions in the blood serum decreases.
Hence, the correct answer is 'PTH simulates bone reabsorption /dilution /demineralization'.
Question 6
1 / -0

Which of the following hormones promotes the conversion of glucose into glycogen?

A
Glucagon

B
Adrenaline

C
Insulin

D
Progesterone
Solution
Sugar in the human body is present either in the form of glycogen or glucose.
Glucose is the sugar present within the blood which is utilized by the body to obtain energy.
Whereas, glycogen is the stored form of sugar present in the liver and muscles.
When the level of glucose in the blood increases, the insulin produced by the pancreas convert some of the glucose into glycogen.
When the body requires sugar, a hormone called glucagon is secreted by the pancreas which stimulates the liver to convert some of the stored glycogen into glucose which is released into the bloodstream.
So, the correct answer is 'Insulin'.
Question 7
1 / -0

Hyper secreation of Parathyroid hormone result in ___________________.

A
Stronger bones due to increased incorporation of calciuim in them.

B
Deposition of calcium in various skeletal structure.

C
No effect on the constitution of bones

D
Weaker bones due to increased removal of calcium from them

Solution

A parathyroid gland tumor can prompt hypersecretion of PTH. This can raise blood calcium levels so excessively that calcium deposits begin to accumulate throughout the body, including in the kidney tubules. When calcium levels in your blood fall too low, your parathyroid glands secrete enough PTH to restore the balance but sometimes these glands produce an excess amount of hormone, leading to abnormally high levels of calcium (hypercalcemia) and low levels of phosphorus in your blood.
So, the correct answer is 'Deposition of calcium in various skeletal structures.'
Question 8
1 / -0

Which of the following is not associated with parathyroid hormone (PTH)?

A
It promotes release of $$Ca^{2+}$$ from bone matrix into the blood

B
It stimulates kidney to release calcitriol

C
More PTH is released when blood calcium level rises

D
Hypoparathyroidism result in parathyroid terany
Solution
- Parathyroid hormone- It is also known as parathormone or parathyrin.
- It is a secreted by the parathyroid glands.
- Its main function includes bone remodelling by releasing more PTH when the calcium in our blood goes too low, which increases the blood calcium level that is released from bones.
- This hormone stimulates calcitriol production in the kidney as it synthesises 1-α hydroxylase and also maintains calcium levels by increasing calcium absorption in the gastrointestinal tract
- Hypoparathyroidism- leads to low levels of calcium in the blood which causes cramps and twitches in muscles or tetany.
- So, the correct answer is 'More PTH is released when blood calcium level rises'.
Question 9
1 / -0

__________ is a mixed type of gland

A
Thymus

B
Salivary gland

C
Intestinal glands

D
Pancreas

Solution

Some glands have dual functions, e.g., the liver, pancreas, ovary, and testis produce both a secretion that is emitted through a duct and a hormone that is taken up by the blood. Such structures are called mixed glands. So the correct option is 'Pancreas'.
Question 10
1 / -0

Sella turcica is a depression that accommodates the pituitary gland and is found on:

A
$$Sphenoid$$

B
$$Palatine$$

C
$$Alisphenoid$$

D
$$Basisphenoid$$
