Q. 19 - Biology

Question

Which of the following hormones is not produced by the anterior pituitary? 

a. oxytocin 

b. growth hormone 

c. prolactin 

d. thyroid-stimulating hormone 

Step-by-Step Solution

Answer

Option a is the correct answer.

Step 1: Introduction

The pituitary gland plays a significant part in regulating the body's chemical reactions and hormonal effects. The anterior pituitary plays a major function, producing growth hormone, adrenocorticotropic hormone, LH and FSH, prolactin, and other hormones.

Step 2: The explanation for the correct answer

However, the anterior pituitary does not secrete anything; only vasopressin and oxytocin are produced.  Therefore, Option a is the correct answer.

Step 3: The explanation for incorrect options

While the posterior pituitary solely secretes vasopressin and oxytocin, the anterior pituitary typically produces growth hormone, adrenocorticotropic hormone, LH and FSH, prolactin, and other hormones.

Therefore, Options B,C and D are irrelevant to the question.
