Skeletal Muscle
Skeletal muscles are voluntary muscles that enable locomotion and the movement depends on: the type of joint associated with the muscle, the attachment of muscle on either side of the joint, the origin (one end of a skeletal muscle to an immovable part of the joint), the insertion (other end of a muscle that connects to the movable part on the other side of the joint).
Skeletal muscles function in groups:
The fascia is connective tissue that holds together muscles and surrounds muscle and projects beyond the end in order to form a tendon. These tendons then intertwine with the periosteum which attaches muscle to the bone. The innermost layer of the fascia that is closest to the muscle tissue known as the epimysium. The perimysium separates the muscle into smaller compartments called fascicles. A thin covering, known as endomysium, is found within the fascicle and surrounds the muscle fibers.
Skeletal muscles are made up of thin, elongated fibers with rounded ends. They are striated (striped), contain multiple nuclei, are attached to bones, and control voluntary movements of the skeletal parts.
Skeletal muscles function in groups:
- Agonist: primer mover
- Synergist: contract to assist the agonist
- Antagonist: resist a prime mover's action and cause the the muscle to move in the opposite direction
