Best Answer

Oxytocin stimulates the uterine muscles to contract and also increases the production of prostaglandins, which increase the contractions further. Manufactured oxytocin is sometimes given to induce labour if it has not started naturally or it can be used to strengthen contractions to aid childbirth.

The hormone oxytocin aids the birth process by stimulating?

To stimulate uterine contraction.


What stimulates the uterine contraction?

Stimulation of the cervix is what triggers labor through a hormone called oxytocin.


What hormone stimulates contraction of the uterus and mammary glands?

Uterine contractions are stimulated by the release of Oxytocin a hypothalamic hormone which has uterine contracting and milk releasing actions.


Which gland releases hormones into the bloodstream that aid in the stimulation of uterine contraction?

The pituitary releases oxytocin into the bloodstream to stimulate uterine contraction. This process is one of the few endocrine processes that relies on a positive feedback loop.


How could you describe the positive feedback system that occurs during labor?

The process of labor is induced by the release of the hormone Oxytocin from the pituitary gland. Oxytocin causes smooth muscle contraction associated with the uterus. Uterine contraction in turn causes the release of more Oxytocin from the pituitary, which causes more contraction. this represents a positive feedback loop of increasing amounts of Oxytocin and uterine contraction. Contractions of the uterus of course result in the movement of the fetus out of the birth canal (leaving the uterus, passing through the cervix, and out through the vaginal opening.


What hormone made by the hypothalamus causes uterine contraction during childbirth and milk let-down when a baby is nursing?

Oxytocin


Does oxytocin prevents premature births?

No oxytocin is used to stimulate labor. In humans, oxytocin stimulates milk let down during lactation, uterine contraction during birth and is released during sexual orgasm in both men and women.


What are the organ and system involved when uterine contraction occurs?

uterus is the organ and reproductive/endocrine system cause the contraction (hormone-oxytocin is released in the body that causes the contractions to occur. If a woman is induced for labor pitocin is given which is the "man made" form of oxytocin


The hormone that stimulates uterine contractions is?

oxytocin


The hormone stimulates uterine contractions is?

Oxytocin


A hormone that under certain circumstances is regulated by positive feedback is?

Oxytocin in the process of giving birth. Oxytocin causes uterine contraction, which causes the baby to push up against the cervix, which causes more oxytocin to be released. And the cycle continues until the baby is born.


The target tissue for oxytocin are the?

I will quote John E. Morley, MB, BCh for this one:Oxytocin has 2 major targets: the myoepithelial cells of the breast, which surround the alveoli of the mammary gland, and the smooth muscle cells of the uterus. Suckling stimulates the production of oxytocin, which causes the myoepithelial cells to contract. This contraction causes milk to move from the alveoli to large sinuses for ejection (ie, the milk letdown reflex of nursing mothers).Oxytocin stimulates contraction of uterine smooth muscle cells, and uterine sensitivity to oxytocin increases throughout pregnancy. However, plasma levels do not increase sharply during parturition, and the role of oxytocin in the initiation of labor is unclear. There is no recognized stimulus for oxytocin release in men, although men have extremely low levels.
