The existence of a neurohormone with effects on uterine muscle tissue was demonstrated in 1906, when English physiologist Sir Henry Dale found that extracts of posterior pituitary glands from oxen, when administered to animals such as cats and dogs, encouraged the uterus to contract. Your hypothalamus makes oxytocin, but your posterior pituitary gland stores and releases it into your bloodstream.

Hormones are chemicals that coordinate different functions in your body by carrying messages through your blood to your organs, muscles and other tissues. Oxytocin and its receptors also play a role in pro-social behaviours, including in social motivation, social recognition, trust, and pair-bonding.

Once your baby stops feeding, the release of oxytocin stops until the next feeding. Oxytocin is a peptide hormone secreted by the posterior pituitary. The two genes are usually located close to each other (less than 15,000 bases apart) on the same chromosome, and are transcribed in opposite directions (however, in fugu,[57] the homologs are further apart and transcribed in the same direction). In some women, the cry of a hungry baby or other cues associated with an infant may stimulate milk letdown, suggesting a conditioning effect, whereby certain cues trigger the release of oxytocin. [30][31][32] This precursor protein also includes the oxytocin carrier protein neurophysin I. and pH adjusted to 3.0 to 5.0 with acetic acid.

[29] In accordance, unlike oxytocin, the selective non-peptide oxytocin receptor agonist WAY-267,464 does not produce antidepressant-like effects, at least in the tail suspension test. Its actions are mediated by specific oxytocin receptors. [105] Individuals who receive an intranasal dose of oxytocin identify facial expressions of disgust more quickly than individuals who do not receive oxytocin. Thus, oxytocin increases the salience of cues that imply contamination, which leads to a faster response because these cues are especially relevant for survival. Effect of ACTH and oxytocin treatment on lactoferrin and citrate in cows' milk. According to a study published in 2014, silencing of oxytocin receptor interneurons in the medial prefrontal cortex (mPFC) of female mice resulted in loss of social interest in male mice during the sexually receptive phase of the estrous cycle. Females who are administered oxytocin are overall faster in responding to socially relevant stimuli than males who received oxytocin. relationship between luteal concentrations of oxytocin (OT), noradrenaline (NA), progesterone (P4), oxytocin receptors (OT-R) and beta (2)-adrenoreceptors . The deduced structure of the active nonapeptide is: The term "oxytocin" derives from the Greek "" (kutkos), based on (oxs), meaning "sharp" or "swift", and (tkos), meaning "childbirth".
