ANATOMY

Detailed explanation-1: -The release of oxytocin from the posterior pituitary gland during labor is an example of positive feedback mechanism. Oxytocin stimulates the muscle contractions that push the baby through the birth canal. The release of oxytocin result in stronger or augmented contractions during labor.

Detailed explanation-2: -Normal childbirth is driven by a positive feedback loop. A positive feedback loop results in a change in the body’s status, rather than a return to homeostasis.

Detailed explanation-3: -Understanding Positive Feedback : Example Question #3 Explanation: Contraction of the uterus during childbirth causes the release of oxytocin, which stimulates stronger contractions of the uterus, causing more oxytocin release. This perpetual cycle results in a positive feedback response.

Detailed explanation-4: -Oxytocin stimulates uterine contractions at parturition, smooth muscle contraction in the mammary glands during suckling, maternal behavior, and affects water homeostasis.
