oxytocin: a pituitary octapeptide hormone C43H66N12O12S2 that stimulates especially the contraction of uterine muscle and the secretion of milk.
Oxytocin ( /ˌɒksɨˈtoʊsɪn/) is a mammalian hormone that acts primarily as a neuromodulator in the brain. Oxytocin has the distinction of being the very first polypeptide hormone to be sequenced and synthesized biochemically, by Vincent du Vigneaud et al. in 1953.[1]
Oxytocin is best known for its roles in female reproduction. It is released in large amounts 1) after distension of the cervix and uterus during labor, and 2) after stimulation of the nipples, facilitating birth and breastfeeding. Recent studies have begun to investigate oxytocin's role in various behaviors, including orgasm, social recognition, pair bonding, anxiety, and maternal behaviors.[2] For this reason, it is sometimes referred to as the "love hormone".[3]
The word oxytocin is a corruption of the Greek ὼκυτοκίνη, ÅkytokÃnÄ“, "quick labor".

Produces oxytocin and ADH that are released within the posterior pituitary gland?
ADH and Oxytocin is produced by hypothalamus.It is secreted by inferior pitutory.
What endocrine organ produces vasopressin?
Vasopressin is produced in the postieror pituitary gland. This glad also produces oxytocin.
What hormones are made by the posterior pituitary?
The posterior pituitary gland only produces two hormones. It produces antidiuretic hormone (vasopressin) and oxytocin.
The hypothalamus produces only two hormones with target organs outside the head ADH and oxytocin true or false?
True
The hormone responsible for stimulating contractions of the uterus is known as?
oxytocin released by the posterior pituitary is one of the main hormones causes contraction.prostaglandin f2 alpha produces by decidua appears to be the principle prostaglandin initiating myometrial contractility.
What is the hormone that is secreted by the pituitary gland that stimulates uterine contractions?
The hormone that stimulates contractions of the uterus in mammals is oxytocin. However, the story is probably rather more complex. In mice, for example, that had no cell membrane receptors for oxytocin, birth took place as usual. Oxytocin has a short peptide molecule consisting of just nine amino acids.
Which hormones help regulate a mares pregnancy and foaling?
Progesterone is the major hormone needed to maintain a pregnancy. In the forst 90 days the corpus luteum on the ovary produces the major amount of progesterone. After 90 days the placenta is the major producer. Initiating foaling is by the production of oxytocin.
How many hormones does neurohypophysis PRODUCE?
NEUROHYPOPHYSIS PRODUCES 1)ADH->kidney -descries urine production if we are thirsty our body produces more ADH) 2) OXYTOCIN -mammary glands (lactation) Uterine muscle(orgasm)
How is the level of oxytocin controlled by a positive-feedback mechanism?
The oxytocin in blood stimulates the pituitary to secrete more oxytocin.
What are the function of oxytocin?
The major functions of oxytocin have to do with smooth muscle contraction.
Does the posterior pituitary gland respond to the gonadotropin-releasing hormone?
no. because the posterior lobe produces no hormones of its own but only stores and releases oxytocin and Antidiuretic hormone
What hormones is regulated by a neuroendocrine reflex oxytocin cortisol antidiuretic hormone?
oxytocin
