BIO 201 Exam I Key Terms - Articulations & Muscle Tissue
Across
- 3. property of muscle tissue, muscle fiber's ability to return to its original length when the tension of contraction is released
- 5. do not run the entire length of the muscle fiber, organized into repetitive groupings, including thin and thick
- 6. located at the end of each muscle where all the connective tissue merges, attaching the muscle to bone
- 9. flatlike appearance of tendons
- 10. complex motion that involves successive flexion, abduction, extension, and adduction
- 11. layer of connective tissue, innermost layer that surround and electrically insulates each muscle fiber
- 13. layer of connective tissue, surrounds individual fascicles
- 14. myosin, a motor protein that "walks" on thin filaments
- 15. actin and associated proteins
- 16. muscle fiber of the sarcoplasm extending entire length of the cell, have ability to shorten, resulting in contraction of the muscle and the production of motion
- 18. property of muscle tissue, ability of a muscle fiber to be stretched beyond its relaxed length
- 19. direction from median plane, anatomic position
- 20. layer of connective tissue, surrounds the entire muscle
- 21. number of skeletal muscles forming the muscular system
Down
- 1. movement of limb or other part towards the midline of the body or to another part
- 2. property of muscle tissue, stimuli can initiate electrical changes in the muscle fiber (cell) leading to contraction
- 4. property of muscle tissue, stimulation leads to contraction or shortening of the muscle fiber
- 7. layer of connective tissue, surrounds each muscle and separates muscles from each other
- 8. point of attachment to the bone that DOES NOT move
- 12. direction to median
- 17. diarthrotic ball-and-socket joint between head of humerus and glenoid cavity of scapula
