Questions Related to testes and ovary

Mammalian prolactin is secreted by 

  1. Adenohypophysis

  2. Neurohypophysis

  3. Adrenal cortex

  4. Adrenal medulla


Correct Option: A
Explanation:

Prolactin (PRL), also known as luteotropic hormone or luteotropin, is a protein, that in humans is best known for its role in enabling female mammals to produce milk. Prolactin is a single-chain protein hormone. It is secreted by the lactotrophs in the anterior pituitary (adenohypophysis).

The formation of egg and sperm is affected by 

  1. LH

  2. MSH

  3. TSH

  4. FSH


Correct Option: D
Explanation:

In women, FSH hormone stimulates the growth of ovarian follicles in the ovary, before the release of an egg from one follicle at ovulation. It also increases oestradiol production. 

In men, follicle stimulating hormone acts on the Sertoli cells of the testes to stimulate sperm production (spermatogenesis).

Acromegaly is a disease caused by 

  1. Over secretion of growth hormone in childhood.

  2. Over secretion of growth hormone in adulthood.

  3. Under secretion of growth hormone in adulthood.

  4. Deficiency of calcium and phosphorous in the diet.


Correct Option: B
Explanation:

Acromegaly is the abnormal growth of the hands, feet, and face. It is caused when there is oversecretion of growth hormone (GH) in adulthood. Similarly, oversecretion of growth hormone in childhood causes Gigantism. 

It is usually caused by a non-cancerous tumor in the pituitary gland.
Its symptoms include large hands and feet, thick lips, coarse facial features, a jutting forehead and jaw, and widely spaced teeth. Thus, the correct answer is option B.

"4s gland" is 

  1. Pancreas

  2. Liver

  3. Thyroid

  4. Adrenal


Correct Option: D
Explanation:

The adrenal gland is known as 4S gland. 4S stands for the source of energy, sugar metabolism, salt retention and sex hormones. 

The adrenal glands, located at the top of each kidney, produce hormones that help the body control blood sugar, burn protein, and fat, react to stressors like a major illness or injury and regulate blood pressure. Two of the most important adrenal hormones are cortisol and aldosterone.

Which organ cells produce gastrointestinal hormones?

  1. Stomach

  2. Pancreas

  3. Small Intestine

  4. All of the above


Correct Option: D
Explanation:

All of the above are gastrointestinal hormones,

Which is the smallest gland in human body?

  1. Liver

  2. Pituitary Gland

  3. Thyroid Gland

  4. Pineal Body


Correct Option: D
Explanation:

The pineal gland, also known as the pineal body, conarium or epiphysis cerebri, is a small endocrine gland in the vertebrate brain.

The thyroid gland is

  1. Unilobed.

  2. Bilobed.

  3. Trilobed.

  4. Tetra-lobed.


Correct Option: B
Explanation:

The thyroid gland is a bilobed organ of the endocrine system located in the front of the neck. It secretes hormones that are involved in human development, growth, and metabolism.

Which gland is also called suprarenal Gland?

  1. Thyroid Gland

  2. Adrenal Gland

  3. Pituitary Gland

  4. Hypothalamus


Correct Option: B
Explanation:

The adrenal glands (also known as supra-renal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys.

The stored form of glucose in liver or muscles is called

  1. Glycogen.

  2. Glucagon.

  3. Glycolysis.

  4. Glycogenesis.


Correct Option: A
Explanation:

When the body has extra glucose, it stores it in the liver and muscles. This stored form of glucose is called glycogen.

Feedback Mechanism is the important for homeostasis.

  1. True

  2. False


Correct Option: A
Explanation:

Homeostasis relates to dynamic physiological processes that help us maintain an internal environment suitable for normal function. Feedback mechanism also helps in maintaining this balance of the hormones in the body.
