Explanation / Answer

1. Tendon - rope like bundle of dense connective tissue

2. Mitochondria - produces ATP for muscle fibres.

3. I band - composed primarily of actin

4. Transverse tubule - carries wave of depolarization through muscle fibres

5. Fascicle - bundle of muscle fibers

6. Z disc - cylindrical subunit of muscle fiber

7. Synaptic vesicles - contain ACh

8. Muscle fiber - a single muscle cell

9. Synaptic cleft - gap between axon terminal and motor end plate

10. Thin myofilament - light region at each end of sarcomere.

11. Axon terminal - forms neuron side of neuromuscular junction.

12. Endomysium - connective tissue encasing a muscle fiber.

13. Sarcoplasmic reticulum - contains high calcium concentration

14. Sarcolemma - muscle fiber plasma membrane

15. Sarcomere - functional subunit of myofibril

16. Motor end plate - highly folded region of sarcolemma; forms muscle side of neuromuscular junction.

17. A band - composed primarily of myosin.

18. Perimysium - connective tissue surrounding fascicle.

19. H zone - light region around M line

20. Acetylcholine - a neurotransmitter

21. Thick myofilament - dense Central region of sarcomere.

22. Epimysium - connective tissue surrounding entire muscle.

23. Myofibril - cylindrical subunit of muscle fiber

24. M line - connects thick filaments down center of sarcomere.

25. Aponeurosis - Tendon that is a broad sheet.
