People with urge incontinence tend to have to pass urine frequently; sometimes having to get up to go to the toilet during the night. Bladder muscles can activate involuntarily because of damage to the nerves of the bladder, the nervous system, or to the muscles themselves.
The muscular system is made up of tissues that work with the skeletal system to control movement of the body. Some musclesâlike the ones in your arms and legsâare voluntary, meaning that you decide when to move them. Other muscles, like the ones in your stomach, heart, intestines and other organs, are involuntary.
Smooth muscle is muscle you rarely control such as the muscle in your intestinal tract. Cardiac muscle is very specific tissue found in your heart. Voluntary muscle is the muscle that helps you move. All of those tissues add up to a muscular system that is found through your body. There is more to the muscular system than the muscles that help you move. The big purpose of the muscles found in your body is movement.
