Oxytocin
Tetanus
Dunno what it does in males (if anything). In females, it stimulates lactation, mostly. If given artificially, it can stimulate contraction of the uterus and parturition (doctors use it to induce labor). But it isn't really clear if the pituitary secretes oxytocin on its own to stimulate labor, or if there is some other mechanism that induces labor.
decreases contraction in the smooth muscle
The smooth endoplasmic reticulum is a vast network of membrane-bound vesicles and tubules. It does the following: 1. lipid and steroid hormone synthesis 2. breakdown of lipid-soluble toxins in liver cells 3. control of calcium release in muscle cell contraction
Stimulation of the cervix is what triggers labor through a hormone called oxytocin.
smooth muscle
Asthma causes contraction of the bronchial smooth muscle.
Vasoconstriction is normal contraction of smooth muscle in the artery wall.
smooth muscle
It can cause vascular smooth muscle contraction
Because it is an involuntaru muscle contraction
smooth muscle
Acetylcholine and norepinephrine both affect smooth muscle contraction. They stimulate contraction in some muscles and inhibits contraction in others.
