Question

Assertion (A): The foetal ejection reflex triggers the release of oxytocin from maternal pituitary.

Reason (R): Oxytocin acts on uterine muscles and causes stronger uterine contractions.

Options

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

Signals from the foetus and placenta initiate the foetal ejection reflex and release oxytocin. Oxytocin strengthens uterine contractions, which further stimulate its release.
