Anatomy and PhysiologyAnatomy and Physiology
• The muscular system moves the bony framework of the body.
• There are approximately 700 skeletal muscles in the body, as well as tendons and other structures of the muscular system.
• Some skeletal muscles are readily visible on the surface of the body, while others are located more deeply.

Anatomy and PhysiologyAnatomy and Physiology
• All of the muscles of the body (or the muscles in a particular part of the body) are referred to as the musculature.
• The muscular system is also known as the musculoskeletal system because, without the muscles, the bones would not be able to move, and without the bones, the muscles would lack support.

Muscle Origins, Insertions,Muscle Origins, Insertions,and Related Structuresand Related Structures
• A muscle is attached to a bone by a tendon, a cordlike, nonelastic, white fibrous band of connective tissue.
• The origin or beginning of a muscle is where its tendon is attached to a stationary or nearly stationary bone.

• The insertion or ending of a muscle is where its tendon is attached to the bone that moves when the muscle contracts and relaxes.
• The belly of a muscle is where its mass is the greatest, usually midway between the origin and insertion.

Physiology of a Muscle ContractionPhysiology of a Muscle Contraction
• A muscle is composed of several muscle fascicles, each of which is wrapped in fascia.
• Each muscle fascicle is a bundle of individual muscle fibers.

• These run parallel to each other so that, when they contract, they all pull in the same direction.
• A muscle fiber (which is actually one long muscle cell) has hundreds of nuclei along its length to speed up the chemical processes that occur as it contracts.

Physiology of a Muscle ContractionPhysiology of a Muscle Contraction
• Each muscle fiber is composed of myofibrils that contain the proteins actin and myosin.
• A muscle contracts in response to an electrical impulse from a nerve.
• Each muscle fiber is connected to a single nerve cell at the neuromuscular junction.

Physiology of a Muscle ContractionPhysiology of a Muscle Contraction
• Acetylcholine is a chemical messenger that changes the permeability of the muscle fiber, which shortens the muscle and produces a muscle contraction.
• Muscles are in a state of mild, partial contraction because of nerve impulses from the brain and spinal cord.
