The plasma membrane of a skeletal muscle fiber is called thesarcolemma.The sarcolemma is the site of action potential conduction, which triggers muscle contraction. Within each muscle fiber aremyofibrils—long cylindrical structures that lie parallel to the muscle fiber. Myofibrils run the entire lengt...
Quiz Course 241Kviews Skeletal Muscle Location Where is skeletal muscle found? Skeletal muscles are muscles that are connected to and facilitate the movement of the skeleton. They are connected to the outer covering of bones, called the periosteum. This connection to the bone is through a type...
