Across
- 1. - Cell membrane that encloses each muscle cell.
- 5. -point attached to the moveable bone
- 6. -bundle of sheathed muscle fibers
- 8. -gap between muscle cell membranes filled with intertitial fluid
- 10. - The structural and functional unit of a myofibril
- 13. striated involuntary muscle found only in the heart
- 17. degrees of shortening in skeletal muscles
- 19. basic rod-like organelle of a muscle cell
- 21. coarse fibrous membrane that surounds endomysium
- 22. -movement of bone around longitudinal axis
- 23. toughest 'overcoat' of connective tissue surrounding entire muscle
- 25. moving a limb away from the midline of the body
Down
- 2. opposite of abduction-movement of limb toward midline of body
- 3. cordlike things that attach muscled indirectly to bones, cartilages, or connective tissue coverings of each other
- 4. combination of all forms of movement- seen in ball and socket joints- move like a cone in all ways
- 7. muscle cells that package together to form skeletal muscles
- 9. A widespread neurotransmitter found in the CNS and at neuromuscular junctions between peripheral nerves and muscles
- 11. Bundle of sheathed fibers
- 12. movement in sagittal plane that decreases angle of joint and brings two bones closer together
- 14. -point attached to immovable or less movable joint
- 15. -chemical released when nerve impulse reaches axonal terminals
- 16. state of continuous partial contractions-when contraction isnt visible but muscle remains firm and healthy and ready for action
- 18. delicate -connective tissue sheath
- 20. involuntary muscle with no striations found in walls of hollow visceral organs (stomach, bladder, respiratory)
- 23. opposite of flexion-movement that increases angle/distance between bones or parts of body (straightening)
- 24. one neuron and all the skeletal muscle cells it stimulates
