Oxytocin ejects milk from mamary glads.Muscles of uterus are contracted.
The two hormones that target the mammary glands are prolactin and oxytocin. Prolactin is responsible for milk production, while oxytocin triggers the release of milk from the glands during breastfeeding.
Oxytocin is released by posterior pitutory.It is produced by hypothalamus.
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.
Growth hormone has more target cells in the body than any of the others listed. It acts on various tissues and organs to regulate growth, metabolism, and cell regeneration throughout the body.
False. The hypothalamus produces several hormones that regulate various functions in the body, including ADH (antidiuretic hormone) and oxytocin.
Oxytocin's target is the uterus; it helps to contract it when the female gives birth. Oxytocin also releases milk for a baby, so I would say it targets the breasts as well. One thing that I have found and am not so sure of is that it affects the brain; it enhances bonding and trust between humans. If this is for homework though, you'll make your teacher happy if you just write "Uterus and breasts".
The major functions of oxytocin have to do with smooth muscle contraction.
Yes, oxytocin is a protein hormone produced in the brain.
Oxytocin release is controlled by a positive-feedback mechanism during childbirth. When contractions of the uterus stimulate oxytocin release, this hormone further intensifies contractions, leading to more oxytocin release. This cycle continues until the baby is delivered.
oxytocin
Oxytocin is a peptide hormone and is removed by enzymatic cleavage in the plasma.
Oxytocin is a neurohormone that is released to stimulate uterine contractions. When labor is induced, Pitocin is given. This is a synthetic form of oxytocin. Additionally, oxytocin stimulates mammary glands for milk let down in breast feeding mothers.
