  2. E

  3. C

  4. D

Show answer
Correct Option: C
Explanation:

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.

  1. Endocrine glands

  2. Exocrine glands

  3. Embryonic tissue

  4. Simple glands

Show answer
Correct Option: B
Explanation:

Exocrine glands are glands that produce and secrete substances onto an epithelial surface by way of a duct. Examples of Exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, and mucous. 

So, the correct option is B ( Exocrine gland )

Which among the following are ductless glands?

  1. Exocrine gland

  2. Endocrine gland

  3. Mixed gland

  4. None of the above

  1. Ducts

  2. Blood

  3. Both

  4. None of the above

Show answer
Correct Option: B
Explanation:
  • Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct because endocrine glands lack ducts. Hence they are also called ductless glands.
  • The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus, and adrenal glands.
  • Hence endocrine glands put their secretions directly into the blood.
  • So, the correct answer is 'Blood'.

Hormones are produced by

  1. Exocrine glands

  2. Endocrine glands

  3. Holocrine glands

  4. Apocrine glands

Show answer
Correct Option: B
Explanation:
A. Exocrine glands are the glands that secrete their products through ducts.
B. Endocrine glands are the ductless glands which secrete their products directly into the blood.
C. Holocrine glands secrete their products in the cytoplasm which are released due to rupture of cell membrane.
D. Apocrine glands are generally present in the skin and secrete their products on the skin surface.
Hormones are produced by endocrine glands. They are secreted in the blood stream from which they are carried to their target organs.
So, the correct answer is 'Endocrine glands'.

What is the other name of the endocrine glands?

  1. Duct gland

  2. Normal

  3. Ductless gland

  4. Oesophagus

Show answer
Correct Option: C
Explanation:
  • Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct because endocrine glands lack ducts. Hence they are also called ductless glands.
  • The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus, and adrenal glands.
  • Hence the other name of the endocrine glands is ductless gland.
  • So, the correct answer is 'Ductless gland'.

Which of the following are incorrectly matched

zoology endocrine system and adolescence control of blood glucose endocrine system and hormone hormones in human reproduction

  1. Synthesis reaction-anabolism

  2. Decomposition reaction-catabolism

  3. Hydrolysis-anabolism

  4. Dehydration reaction-synthesis reaction

Show answer
Correct Option: C
Explanation:
Hydrolysis is the cleavage of biomolecules where a water molecule is consumed to affect the separation of a larger molecule into component parts. So, hydrolysis is a type of decomposition and that's why it is regarded as catabolism.
Hence, the correct answer is 'Hydrolysis-anabolism'

Select the correct matching of a hormone , it's source and function.

zoology endocrine system and adolescence control of blood glucose endocrine system and hormone hormones in human reproduction

  1. Vasopressin,  posterior pituitary,  Increase loss of water through urine

  2. Norepinephrine, Adrenal medulla, Increase heartbeat, increase rate of respiration and alertness

  3. Glucagon, Beta-cells of islets of langerhans, stimulates glycogenolysis

  4. Prolactin, Posterior pituitary and mammary glands, Regulates growth and milk formation in females

Show answer
Correct Option: B
Explanation:

Vasopressin is released by the posterior lobe of the pituitary gland and it stimulates the reabsorption of water and electrolytes. 

Norepinephrine is secreted by the adrenal medulla and it increases the alertness, heartbeat and respiratory rate.
Glucagon is released by alpha cells and it increases the blood sugar level.
Prolactin is released by the anterior lobe of the pituitary gland and it helps in the regulation of mammary glands and the formation of milk in them. 
Thus, the correct answer is 'Norepinephrine, Adrenal medulla, Increase heartbeat, increase rate of respiration and alertness.'
