Question

Oxytocin and vasopressin are two hormones secreted by posterior lobe of pituitary. Removal of posterior pituitary from a mammalian brain will lead to

• A. Increased production of oxytocin and vasopressin
• B. No production of oxytocin and vasopressin
• C. Oxytocin production will increase but vasopressin production will decrease
• D. No effect on oxytocin and vasopressin production

Answer 1

The correct option is D No effect on oxytocin and vasopressin production

Oxytocin and vasopressin are hormones produced by hypothalamus and it is stored and secreted by posterior pituitary. Hence removal of posterior pituitary will show no impact on production of these two hormones.
