A Correct answer
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

D Correct answer
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.
Reveal answer Fill a bubble to check yourself
B Correct answer
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
Reveal answer Fill a bubble to check yourself
D Correct answer
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.

Multiple choice biology excretory system of human control of blood glucose parts of the brain kidney

Nitrogenous wastes can be removed from the body by

  1. Urinary system

  2. Lymphatic system

  3. Circulatory system

  4. Respiratory system

  5. Integumentary system
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The urinary system produces urine (nitrogenous water) and serves to excrete it to outside the body. Lymphatic system serves in fluid balance, fat absorption and defense. The circulatory system serves in exchange of nutrients and oxygen for waste and carbon dioxide respectively. Respiratory system serves to allow entry of oxygen from the air into blood and exit of carbon dioxide from blood to the air. The integumentary system covers the entire surface of the human body and serves as a barrier, site for waste elimination and temperature control. 

So, the correct answer is option A.

The human hind brain comprises of three parts, which one of these belongs to hind brain?

  1. Cerebellum

  2. Hypothalamus

  3. Spinal cord

  4. Corpus callosum
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The hindbrain is the lowermost or rearmost region of the brain that bridges the brain with the spinal cord and includes the medulla oblongata, pons and cerebellum. It is also called the rhombencephalon.  

So, the correct answer is 'Cerebellum'

Which of the following is true about cerebrum?

  1. It is poorly developed in humans

  2. It consists of two hemispheres, left and right

  3. It controls the pituitary gland

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cerebrum is the largest part of the brain and well developed in humans. It plans, thinks, judges, and organised speech and information. It consists of two hemispheres, left and right connected by corpus callosum. 

Pituitary gland is controlled by hypothalamus.
So, the correct answer is 'It consists of two hemispheres, left and right'.
