This process is called contraction. Muscles shorten or contract to produce movement.
Smooth muscles
After electricity reaches the muscles, it triggers the release of calcium ions within the muscle fibers. This causes the muscle fibers to contract and generate force, allowing movement to occur.
Oxytocin is the primary chemical that causes contractions in the human body, specifically in the uterus during labor and also in the mammary glands during breastfeeding. Additionally, prostaglandins are also involved in stimulating contractions in various smooth muscles, including those in the uterus.
Contract and Relax
Oxitosin is the hormone. It is secreted by pituitary.
They also cause the muscles of the uterus to contract, thus helping the uterus shed the lining built up during the first part of a woman's cycle.

it is a problem in the nervous system
beta blockers
