Across
- 4. Cycle, A repeating sequence of events that causes the filaments to slide, and it consists of four steps.
- 7. How it is called the plasma membrane of the muscle cell?
- 8. Organelles that run all the muscle fiber.
- 10. fifty, How many skeletal muscles are in the human body?
- 11. Are attached to the bones of the skeleton, and the contraction of skeletal muscle causes the bones at a joint to move:
- 14. joints, Type of joint that has freely movable joints, and the two bones are separated by a cavity:
- 15. filament theory, What is the name of the movement of the actin filaments in relation to myosin filaments?
- 18. Tissue, Provides strength and protection to the muscle and surrounds it as well as the muscle fibers.
- 19. outermost layer of connective tissue that surrounds the muscle.
- 20. joints, Type of joint that is immovable , and is held by fibrous tissue.
- 21. Movements, Movement thta occurs i the synovial joint. Example of this movements: lexion,extension,lateral flexion, hyperextension, abduction, adduction, and circumduction.
Down
- 1. Stroke, There are four steps of the contraction cycle:
- 2. ions, What is essential for muscle contraction?
- 3. When the bone revolves around its own longitudinal axis.
- 5. , Synonim of Joint. A point of contact between bones.
- 6. fibers, Skeletal muscle is considered a separate organ, and it is composed of thousands of cells called:
- 9. Is a thin sheath of areolar connective tissue that surrounds each individual muscle fiber:
- 12. junction, A small gap, called a synaptic cleft, separates the axon terminal from the sarcolemma, what does it form?
- 13. tissue, It surrounds muscle fibers as well as whole muscles, providing strength and protection to the muscle:
- 16. ATP hydrolosis, Attachment of myosin to actin to form crossbridges, detachment of myosin form acting…What is the other step?
- 17. Movement that occurs in the synovial joint where a flat bone surfaces move back and forth and from side to side with respect to one another. Limited in range.
