sphincters are: | skeletal muscles |
epimysium: | dense layer of collagen fibre surrounding muscle |
perimysium | fibrous layer dividing skeletal muscle into bundles of fibres called muscle fascicles |
endomysium | delicate connective tissue surrounding individual muscle fibres |
bundle of collagen fibres that connect muscle to bone is a: | tendon |
sheet of collagen fibres that connect muscle to bone is a: | aponeurosis |
difference between a tendon and an aponeurosis: | tendon is a fibre, aponeurosis is a sheet that connects muscles to a broader area of bone |
sarcolemma is a: | muscle cell membrane |
sarcoplasm is a: | muscle cell cytoplasm |
sarcoplasmic reticulum is a: | muscle cell endoplasmic reticulum |
myofilaments contain: | thin filaments of actin and thick filaments of myosin |
myofibrils are made of: | myofilaments |
