NEET Zoology Hormones MCQ Question
Which combination of statements about hormones is correct?
Adrenaline and noradrenaline are produced by the adrenal medulla and are known as emergency hormones.
Insulin decreases blood glucose levels by stimulating glycogen breakdown in the liver.
Melanocyte stimulating hormone (MSH) regulates skin pigmentation and is secreted by the pars intermedia.
Oxytocin is responsible for stimulating water reabsorption in the kidneys and is produced in the anterior pituitary.
Correct Answer
Detailed Explanation
Adrenaline and noradrenaline, produced by the adrenal medulla, are indeed referred to as emergency hormones. Insulin functions to lower blood glucose levels by promoting glycogenesis, not glycogen breakdown. MSH regulates pigmentation and is secreted by the pars intermedia but is not the main hormone of the anterior pituitary. Oxytocin is involved in uterine contraction and milk ejection, not water reabsorption, which is the role of vasopressin.
