1. Excitability. The ability to receive and respond to a stimulus.
2. Contractivility. The ability of a muscle to shorten when it is stimulated.
3. Extensibility. The stretching movement of a muscle.
4. Elasticity. the ability of a muscle to recoil to its resting Length.
5. The Function of Skele- It produces movement, maintains posture and body posture, supports soft
tal Muscle. tissue, guards body entrances and exits, maintains body temperature, and
store nutrients.
6. Skeletal Muscles. Organs composed mainly of skeletal muscle tissue, but they also contain
connective tissue, blood vessels, and nerves.
7. Epimysium. A dense layer of collagen fibers that surround the entire muscle.
8. Perimysium. It divides the skeletal muscle into a series of compartments.
9. Fascicle. A bundle of muscle fibers in each compartment.
10. Endomysium. It surrounds the individual skeletal muscle cells.
11. Myosatellite Cells. Stern cells that help repair damaged muscle cells.
12. Tendon. The bundle that forms when the collagen fibers of the epimysium, per-
imysium, and endomysium come together.
13. Aponeurosis. The broad sheet that forms when the collagen fibers of the epimysium,
perimysium, and endomysium come together.
14. Myoblasts. Groups of embryonic cells that fuse during development, forming individ-
ual multinuclaete skeletal fibers.

Another name for skeletal muscle, due to having visible striated fibers
under microscope.
16. Sarcolemma The plasma membrane of a muscle fiber that surrounds the sarcoplasm.
17. Sarcoplasm. Cytoplasm of the muscle fiber.
18. Transverse Tubules or They are narrow tubes whose surface are continuous with the sarcolemma
T Tubules. and extend and extend deep into the sarcoplasm.
19. Sarcoplasmic Reticu- A membrane that forms a tubular network around each myofibril, fitting
lum (SR). over it like lacy shirtsleeves.
20. Terminal Cisternae. A expanded chamber that forms when the tubules of the SR enlarge and
fuse.
21. Triad. The combination of a pair of terminal M plus a T tubule.
22. Myofibril. it is a 1-2 micron in diameter and as long as the entire muscle fiber.
23. Function of Myofibril. it is responsible for skeletal muscle fiber contraction.
24. Myofilaments. A bundle of protein filaments that the myofibrils consist of.
25. Sarcomeres. The smallest functional units of the muscle fiber.
26. The Sacomere.
27. A Bands. The dark bands of a sarcomere.
28. I Bands. The light bands of a sarcomere.
29. The Divisions of Thin M line, H band, and zone of overlap.
