  • Question 1
    1 / -0
    Central tolerance takes place in
    Solution
    Central tolerance is the tolerance established by deleting autoreactive lymphocyte clones before they develop into fully grown immunocompetent cells. It occurs primarily in the thymus.
    So, the correct option is 'Thymus'.
  • Question 2
    1 / -0
    Which of the following is secreted by the pituitary gland?
  • Question 3
    1 / -0
    Which of the following does not favour the formation of large quantities of dilute urine?
    Solution
    ANF or atrial natriuretic factor is a peptide hormone that is secreted by the cardiac muscles. This hormone increases the blood flow in the vasa recta which washes the solutes out of the medullary interstitium. This leads to less absorption of tubular fluids and more excretion. It concentrates the urine. It also inhibits the secretion of renin. Alcohol and caffeine, on the other hand, produces large quantities of diluted urine.
    So, the correct option is 'Atrial-natriuretic factor'.
  • Question 4
    1 / -0
    Which of the following statements about 'neuro-hypophysis' is correct?
    Solution
    Neurohypophysis or the posterior lobe of pituitary gland consists of axonal endings of neurosecretory neurons located in hypothalamus. Oxytocin and vasopressin are the hormones secreted by hypothalamus but stored and released by neurohypophysis.
  • Question 5
    1 / -0
    Secretion of which of the following is under control of neuro-secretory nerve cells?
    Solution
    The neurosecretory cells of the hypothalamus secrete releasing factors(neurohormones) that regulate the secretion of hormones from the anterior pituitary.
  • Question 6
    1 / -0
    Endocrine glands have _________ to carry their secretions to the specific organ.
    Solution
    Endocrine glands lack ducts and pass their secretions into the surrounding blood for transport to the site of action. They are also called ductless glands. Their secretions are known as hormones.
  • Question 7
    1 / -0
    The function of pineal body is to.
  • Question 8
    1 / -0
    The gonadotropic hormones are secreted by ______________.
    Solution
    Anterior lope of the pituitary gland secrets gonadotropic hormone which acts on gonads to increase the production of sex hormone and stimulate production of either sperm or ova.
    So, option A is the correct option.
  • Question 9
    1 / -0
    What is the effect of GnRH produced by hypothalamus?
    Solution
    Gonadotropin releasing hormone(GnRH), stimulates the anterior lobe of pituitary gland(adenohypophysis) to secrete two gonadotropins, FSH and LH. In males LH stimulates the Leydig's cells of the testis to secrete androgens.
  • Question 10
    1 / -0
    Melatonin is secreted by.
    Solution
    Correct Option: A
    Explanation:
    • The pineal gland produces the hormone melatonin. That's a pea-sized gland located directly above the brain's center. 
    • It aids your body in determining when to sleep and wake up.
    • At night, your body produces more melatonin than during the day. 
    • When the sun sets in the evening, the levels normally begin to rise. 
    • When the sun rises in the morning, they fall.
    •  How much your body creates is determined on the quantity of light you get each day, as well as your individual biological clock.
    Hence, Melatonin is secreted by the pineal body.
