GENERAL HISTOLOGY

Detailed explanation-1: -The oxytocin travels to your uterus and stimulates contractions. These uterine contractions, in turn, cause your pituitary gland to release more oxytocin, leading to an increase in both the intensity and frequency of contractions.

Detailed explanation-2: -The two main actions of oxytocin in the body are contraction of the womb (uterus) during childbirth and lactation. Oxytocin stimulates the uterine muscles to contract and also increases production of prostaglandins, which increase the contractions further.

Detailed explanation-3: -Oxytocin injection is used to begin or improve contractions during labor. Oxytocin also is used to reduce bleeding after childbirth. It also may be used along with other medications or procedures to end a pregnancy.

Detailed explanation-4: -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.
