Throughout the pregnancy, as the uterus enlarges and stretches, the uterine ____________ prepares itself for uterine contractions. In the later stages of pregnancy, the increasing levels of ____________ counteract the calming influence of ____________ on the uterine myometrium, and ____________ the uterine myometrium sensitivity.

Respuesta :

During pregnancy, MYOMETRUM prepares for contractions. In the later stages, increasing levels of ESTROGEN counteract PROGESTERONE on the myometrium and INCREASE its sensitivity. Estrogen is a sex hormone.

Estrogen and progesterone are the main sex hormones that women have.

A woman produces a high level of estrogen during pregnancy in order to improve vascularization of the uterus and placenta.

This hormone (estrogen) promotes the production of receptors for oxytocin hormone in the myometrium.

Estrogen plays a fundamental role in expanding the myometrium during pregnancy and the contractile response before and during labor pregnancy.
