Vedclass · Answer

(D) Let's analyze each pair:$1$. $(a)$ Pineal gland: It secretes melatonin,which regulates the circadian rhythm. Metabolism and mental retardation are associated with thyroid hormones,not the pineal gland. Thus,$(a)$ is incorrect.$2$. $(b)$ Thymus: The thymus gland is involved in the maturation of $T$-lymphocytes. Myasthenia gravis is an autoimmune disorder often associated with thymic abnormalities. Thus,$(b)$ is correct.$3$. $(c)$ Thyroid: Thyroid hormones (T3,T4) regulate basal metabolic rate,protein synthesis,and development. Anti-inflammatory reactions are primarily regulated by glucocorticoids (cortisol) from the adrenal cortex. Thus,$(c)$ is incorrect.$4$. $(d)$ Pancreas: The pancreas secretes insulin and glucagon. $A$ deficiency or dysfunction in insulin leads to diabetes mellitus,which is characterized by chronic hyperglycemia. Thus,$(d)$ is correct.Therefore,the incorrectly matched pairs are $(a)$ and $(c)$.

List-$I$	List-$II$
$(a)$ Adenohypophysis	$(1)$ Epinephrine
$(b)$ Adrenal medulla	$(2)$ Somatotropin
$(c)$ Parathyroid gland	$(3)$ Thymosin
$(d)$ Thymus gland	$(4)$ Parathormone

Which of the following pairs are incorrectly matched?
$(a)$ Pineal gland - Metabolism,mental retardation
$(b)$ Thymus - Myasthenia gravis
$(c)$ Thyroid - Anti-inflammatory reaction
$(d)$ Pancreas - Chronic hyperglycemia
