Human skeletal muscle

Human skeletal muscle is the type of muscle attached to bones that enables voluntary movement, such as walking and lifting. Composed of long, fibrous cells called muscle fibers, it contracts when nerve signals tell it to do so, generating force. These muscles are made up of many muscle fibers bundled together, supported by connective tissue. Skeletal muscles also help maintain posture, stabilize joints, and generate heat. Their complex structure allows for precise, powerful, and coordinated movements essential for daily activities and physical performance.
