AIIMS 2019 Zoology Endocrine System MCQ Question

Oxytocin and antidiuretic hormone (ADH), also known as vasopressin, are synthesized in the hypothalamus and subsequently transported to the posterior pituitary gland for storage and release into the bloodstream. Option A is incorrect because the anterior pituitary does not produce these hormones; it secretes different hormones such as growth hormone and prolactin. Options C and D are also incorrect, as the pineal gland primarily secretes melatonin, while the thymus is involved in immune function and does not produce oxytocin or ADH. Understanding the distinct roles of these glands is crucial for grasping endocrine system functions.
