A member asked:
Oxytocin and vasopressin are both hormones, right, but what do they do?

Causes contractions: Vasopressin causes constriction and contraction of the small blood vessels(arterioles). Oxytocin cause contractions of the smooth muscle of the uterus. Both of these entities are made in a place some distance form their target organs but are very effective in the job they do.

More than we thought: For 100yrs oxytocin's role was believed to mainly involve empowering contractions in labor.Also some role in lactation "let-down".Recently found to help people connect w/ others emotionally & also decrease anxiety. Both effects make it ripe for study in autism, schizophrenia, etc.Those studies are starting & i've begun rxing it.Similar chemically, vasopressin mainly concentrates urine-& maybe more?
