What else can I help you with?
What organ causes uterine contractions?
Oxytocin causes the uterus to contract. Oxytocin is released by the posterior pituitary gland.
What causes lactation in females?
Oxytocin
What is the hormone that causes milk letdown?
oxytocin
What causes the muscles of the uterus to contract?
Oxytocin.
What is the hormone that causes ejection of milk?
prolactin - anterior pituitary gland oxytocin - posterior pituitary gland
What hormones are regulated by positive feedback under certain circumstances?
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.
Oxytocin acts primarily on the kidneys and causes them to conserve water?
FALSE.
What causes muscles of the uterus to contract during childbirth?
Oxitosin is the hormone. It is secreted by pituitary.
What is oxytocin and what role does it play in human reproduction?
Oxytocin is a hormone released by the pituitary gland. It causes increased contraction of the uterus during labor. Next time, actually do your bio homework though (;
Which chemical causes contractions in the human body?
Oxytocin is the primary chemical that causes contractions in the human body, specifically in the uterus during labor and also in the mammary glands during breastfeeding. Additionally, prostaglandins are also involved in stimulating contractions in various smooth muscles, including those in the uterus.
What causes the let down reflex?
The let-down reflex is triggered by the hormone oxytocin, released by the pituitary gland in response to the baby suckling at the breast. Oxytocin causes the muscles around the milk-producing cells in the breast to contract, pushing the milk into the milk ducts for the baby to feed. Emotional and physical relaxation also play a role in the let-down reflex.
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.
