The visceral muscles are controlled by the unconscious part of the brain and are known as involuntary muscles. Found inside of organs such as the kidneys, intestine and blood vessels, they are the weakest of the three muscle tissue types. The visceral tissue makes the organs contract so that the organs can move substances through the organ. Visceral muscles are known sometimes as smooth muscles because of the smooth appearance they have under a microscope compared to the banded appearance of the cardiac and skeletal muscles.
Even though the muscles are involuntary does not mean they can not be felt or be aware of on a cellular level
