| Question | Answer |
|---|---|
| what are the 3 types of muscle | skeletal muscle, cardiac muscle, and smooth muscle |
| skeletal muscle tissue functions: | contractions pull on tendons to move bones, maintains body posture and position, support weight of organs and tissue, provide nutrient reserves |
| 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 |
