Muscle Contractions: How Neurotransmitters And Chemical Reactions Move Muscles And Bones
How do the bones of the human skeleton move? Skeletal muscles contract and relax to mechanically move the body. Messages from the nervous system cause these muscle contractions. The whole process is called the mechanism of muscle contraction and it can be summarized in three steps:. Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron. The neuromuscular junction is the name of the place where the motor neuron reaches a muscle cell.

A whole skeletal muscle is considered an organ of the muscular system. Each organ or muscle consists of skeletal muscle tissue , connective tissue , nerve tissue , and blood or vascular tissue. Skeletal muscles vary considerably in size, shape, and arrangement of fibers. They range from extremely tiny strands such as the stapedium muscle of the middle ear to large masses such as the muscles of the thigh. Some skeletal muscles are broad in shape and some narrow. In some muscles the fibers are parallel to the long axis of the muscle; in some they converge to a narrow attachment; and in some they are oblique.

Comprehensive Human Physiology
Striated skeletal muscles have characteristic cross-striations which are due to the regular arrangement of contractile elements, the sarcomeres. Striated skeletal muscles contract in response to nerve impulses from the motor neurons of the central nervous system CNS or at the conscious level. They are related to skeletal segments. The striated cardiac muscle of the heart is called the myocardium. Microscopically, cardiac muscle fibers are marked by transverse striae, which are also present on skeletal muscle fibers, as well as other transverse striations that make up the joint areas of the fibers.
