• B. Median lobe
• C. Posterior lobe
• D. Not any particular lobe

Answer 1

Answer: (B)

Median lobe

Pituitary gland has two parts:

• Adenohypophysis : It is formed of two lobes:

1. Anterior lobe - It secretes growth hormone, follicle stimulating hormone, luteinizing hormone, prolactin, adrenocorticotropic hormone and thyroid stimulating hormone.
2. Intermediate lobe (or median lobe) - It secretes melanocyte stimulating hormone.

• Neurohypophysis: It is formed of posterior lobe and secretes oxytocin and vasopressin.

So, the correct answer is 'Median lobe'.
