Question

In a pregnant woman having prolonged labor pains, if childbirth has to be hastened i.e., to aid parturition, it is advisable to administer a hormone that can

• A. Activate the smooth muscles.
• B. Increase the metabolic rate.
• C. Release glucose into the blood.
• D. Stimulate the ovary.

Answer 1

The correct option is A Activate the smooth muscles.

Administration of oxytocin is usually carried out during parturition. Oxytocin stimulates the uterine smooth muscles to contract and also increases production of prostaglandins, which increase the contractions further during labour.
