Question

Which of the following statements related to pituitary gland are correct? (a) It is divided anatomically into adenohypophysis and neurohypophysis (b) It secretes follicle stimulating hormone (c) It secretes melanocyte stimulating hormone (d) It does not secrete prolactin Choose the correct answer from the options given below :

• A. (b) and (c) only
• B. (a) and (b) only
• C. (a), (b) and (c) only
• D. (c) and (d) only

Hint:

Important pituitary hormones:

• GH

• TSH

• ACTH

• FSH

• LH

• Prolactin

• MSH
Most of these are secreted by the anterior pituitary.

Answer 1

The Correct Option is C

Concept: The pituitary gland is known as the ``master gland'' because it regulates the activity of several other endocrine glands through its hormones. It is attached to the hypothalamus and is located at the base of the brain. Let us examine each statement.

Statement (a) The pituitary gland is anatomically divided into:

• Adenohypophysis (anterior pituitary)

• Neurohypophysis (posterior pituitary)
Hence statement (a) is

correct.

Statement (b) Follicle Stimulating Hormone (FSH) is secreted by the anterior pituitary. Functions of FSH include:

• Stimulating ovarian follicle development in females.

• Stimulating spermatogenesis in males.
Therefore statement (b) is

correct.

Statement (c) The pars intermedia of the pituitary gland secretes Melanocyte Stimulating Hormone (MSH). MSH influences pigmentation processes. Therefore statement (c) is

correct.

Statement (d) Prolactin is secreted by the anterior pituitary gland. Its primary function is:

• Initiation and maintenance of milk production after childbirth.
Hence the statement that pituitary gland does not secrete prolactin is false. Therefore statement (d) is

incorrect. Thus statements \[ (a),\ (b),\ (c) \] are correct. Hence the correct answer is \[ \boxed{(3)\ (a),\ (b)\ \text{and}\ (c)\ \text{only}} \]
