The skeletal muscle system holds our bones in place so that we remain upright. This voluntary system responds when we tell our bodies to use muscles. For example, clenching a fist, making smile, frowning, or kicking a ball. Because the brain controls this smooth muscle, it is considered involuntary. Another kind of muscle is called smooth muscle. Because you don’t have the ability to control smooth muscle activity, this type of muscle is also called in voluntary muscle. Smooth muscle lines the walls of the stomach, intestines, and blood vessels, helping to push food along the digestive tract and the blood through the veins (vessels that carry blood from the body from the body to the heart) and arteries ( vessels that carry blood from the heart to the rest of the body.) The smooth cell muscle in a woman’s uterus or womb helps to push out the baby out of the mother’s body. Smooth muscles in the bladder give people the ability to hold in their urine and help excrete urine. The last main muscle cell is the cardiac cell, controls the beating of the heart.

The Short muscles are small and in different shapes. They do not move a great deal, but they are very powerful. For instance, many short muscles surround the spinal chord. The long muscles are located in the arms and legs, where they cause wide and fast movements of these limbs. Wide muscles are flat and thin. They are located on the walls of the thorax and the abdomen. There, they provide a wide and powerful lining to both the thoracic cavity and the abdominal cavity. With these significant muscles types, there are a great number of movement
