Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Release of milk and contraction of the uterus are controlled by
A
Leutenizing hormone
B
Folicle stimulating hormone
C
Prolactin
D
Oxytocin
Explanation: 

Detailed explanation-1: -Oxytocin is a natural hormone that stimulates uterine contractions in childbirth and lactation after childbirth. It also affects aspects of human behavior and the male and female reproductive systems.

Detailed explanation-2: -How is oxytocin controlled? Oxytocin production and secretion is controlled by a positive feedback mechanism where release of the hormone causes an action that stimulates more of its own release. For example, when contraction of the uterus starts during childbirth, oxytocin is released.

Detailed explanation-3: -The neuropeptide oxytocin acts as a hormone and a neuromodulator, influencing a multitude of human social behaviors, including reproduction. During childbirth and the postpartum period, it plays a key role in regulating and controlling processes that ensure a safe birth and the health of mother and child.

Detailed explanation-4: -Oxytocin has been best known for its roles in female reproduction. It is released in large amounts during labor, and after stimulation of the nipples. It is a facilitator for childbirth and breastfeeding. One of the oldest applications of oxytocin as a proper drug is as a therapeutic agent during labor and delivery.

Detailed explanation-5: -Mechanism of Action Oxytocin increases the sodium permeability of uterine myofibrils, indirectly stimulating contraction of the uterine smooth muscle. The uterus responds to oxytocin more readily in the presence of high estrogen concentrations and with the increased duration of pregnancy.
