Skeletal muscle is made up of bundles known as fascicles. Each fascicle contains individual muscle fibers, which are the cells that make up the muscle.

Every muscle fiber is wrapped in a layer of connective tissue called the endomysium.

Important Parts:

• Muscle Fibers: These are long, tube-like cells that contain tiny units called myofibrils.
• Myofibrils: These are made up of smaller sections called sarcomeres. Sarcomeres are what help muscles contract.
• Fascicles: These are groups of muscle fibers that are held together by another layer of tissue called perimysium.

This special way of organizing muscle helps them work together better, allowing muscles to contract and generate force when we move!
