Answer 1

Right answer is (a) neuroendocrine mechanism

The explanation is: Two major processes induce the contractions of the uterine wall during parturition. The hormones secreted from the pituitary and placenta alongside the reflexes induced by the oxytocin function to stimulate the muscle continuously. Thus this is a neuroendocrine process.
