PATHOLOGY

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: -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-3: -Oxytocin. Oxytocin promotes uterine contractions and lactation. In late pregnancy, it reaches the highest level at night, together with peaks in uterine activity rhythm.

Detailed explanation-4: -Since oxytocin stimulates further contractions of the uterus, which is exquisitely sensitive to oxytocin at the end of pregnancy, a positive feedback loop is activated.
