![]() Muscle pain is a common issue that can signal numerous problems, even if it’s something as simple as overuse. Problems with the junction between the cells - called a synapse - can lead to neuromuscular diseases. During this process, calcium is released into the cells and brings about a short muscle twitch. Muscle movement happens when neurological signals produce electrical changes in muscle cells. Like cardiac muscle, smooth muscle is involuntary and also contracts in response to stimuli and nerve impulses. Its wavelike movements propel things through the bodily system, such as food through your stomach or urine through your bladder. ![]() ![]() Smooth muscle: Smooth muscle makes up the walls of hollow organs, respiratory passageways, and blood vessels.This muscle type also creates the electrical impulses that produce the heart’s contractions, but hormones and stimuli from the nervous system can also affect these impulses, such as when your heart rate increases when you’re scared. This type makes up the walls of the heart and creates the steady, rhythmic pulsing that pumps blood through the body from signals from the brain. Cardiac muscle: Cardiac muscle is involuntary muscle.However, humans do not need to concentrate on individual muscles when moving. These signals and movements are nearly involuntary, yet they do require conscious effort. When the nervous system signals the muscle to contract, groups of muscles work together to move the skeleton. There are more than 600 skeletal muscles, and they makes up about 40 percent of a person’s body weight. Skeletal muscle: This type of muscle creates movement in the body.
