Ans.(b)
Sol. The pancreas is a mixed gland which secretes digestive enzyme and the beta sells of islets of langerhans secrete insulin, alpha cells secrete glucagon, delta cells secrete somatostatin hormone. If the pancreas is defective by any of the reason, then the formation of insulin and glucagon are affected badly.

Ans.(d)
Sol. Insulin is a hormone made in the pancreas, that allows our body to use sugar (glucose) from carbohydrates in the food that we eat for energy or to store glucose for future use. Insulin helps to keep blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia). Lack of Insulin in the body causes diabetes in a person. Diabetes patients have excess urination problem called polyuria.

Show Answer
Ans.(c)
Sol. Oxytocin has been best known for its role in female reproduction. It is released in a large amount during labour and after stimulation of the nipples. It is a facilitator or child birth and breast feeding. Oxytocin plays an important role in the neuroanatomy of intimacy, specifically in sexual reproduction of both sexes, in particular during and after childbirth. It is also known as love hormone and as the “bonding hormone”.

Q9. Which gland secretes the milk ejection hormone oxytocin?
कौन सी ग्रंथि दूध निकास हार्मोन ऑक्सीटॉसिन स्रावित करती है?
(a) Pituitary gland/ पीयूष ग्रंथि
(b) Thyroid gland/ थाइरॉयड ग्रंथि
(c) Parathyroid gland/ पैराथाइरॉइड ग्रंथि
(d) Adrenal gland/ अधिवृक्क ग्रंथि
Show Answer
Ans.(a)
Sol. The pituitary gland is called the master gland of the body which regulates the activities of all the internally secreting glands. Oxytocin is a mammalian neurohypophysial hormone, produced in the supraoptic and paraventricular nuclei of the hypothalamus by nerve axons and stored in the posterior pituitary gland. Oxytocin acts primarily as a neuromodulator in the brain.

(b) Oxytocin / ऑक्सीटोसिन
(c) Interferon / इंटरफेरॉन
(d) Insulin / इंसुलिन
Show Answer
Ans.(b)
Sol. Oxytocin is released in large amounts after distension of the cervix and uterus during labour, facilitating birth, maternal bonding and after stimulation of the nipples, lactation. Both childbirth and milk ejection result from positive feedback mechanisms. Oxytocin hormone is injected to cows and buffaloes to make the milk descend to the udders which is called Pitocin.

Ans.(a)
Sol. The hormone abscisic acid was discovered in the early 1960s and plant biologists have known for decades that it plays crucial role in keeping plants alive during the drought. Abscisic acid causes the temporary closure of stomata when there is a shortage of water. It is very useful for the plants growing in water deficient soil. It functions as antitranspirant and also known as the stress hormone.

Sol. Estrogens hormones are produced primarily by the ovaries. They are released by the follicles on the ovaries and are also secreted by the corpus luteum after the egg has been released from the follicle and from the placenta. The primary function of estrogens is the development of female secondary sexual characteristics. These included breasts, endometrium, regulation of sperm, the menstrual cycle, etc.

Show Answer
Ans.(c)
Sol. Endocrine or internally secreting glands are ductless glands since they lack excretory ducts. Endocrine glands secrete their products, hormones, directly into the blood rather than through a duct. The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, thymus, thyroid gland, parathyroid gland and adrenal glands etc.
