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.
