Muscles Part 1

3. fine motor control
6. typically attach to projections on bone
7. can be stimulated to contract by chemical or electrical signals
8. connective tissue joining muscle to bone; usually rope-like
9. anchor muscle to bones or skin (or other muscles)
10. multiple insertions
13. is attached to tendons
16. connective tissue surrounding bundles of muscle fibers
18. moveable skeletal element/ onlimb: usually distal
19. tissue this tissue contributes to tendon and continues to mesh with periosteum and continues into bone
23. connective tissue surrounding each muscle fiber
25. can contract, generate tension (=pulling force)
26. connection between neuron and skeletal muscle fiber, muscle fiber recieves neurotransmitter(acetylcholine) from neuron to stimulate contraction
27. made of long cylindrical cells called myofibers, multinucleated and striated, attached to skeletal elements or skin, and generates conscious/voluntary actions

1. greater strength
2. sheet-like tendon
4. gross motor control
5. stationary skeletal element; anchors muscle/ on limb: usually proximal
11. greater speed
12. located in the heart, pressurizes blood to circulate it, cells are branched and connected end to end, it is striated, regulated autonomically (involuntary)
14. unit all muscle fibers innervated by single neuron; contracts as unit
15. multiple origins
17. dense connective tissue surrounding muscle
20. returns to resting length after being stretched or contracting
21. innervated by somatic motor neurons
22. found in many organs, regulated autonomically(involuntary), cells are highly stretchable and resistant to fatigue, unstriated
23. can be stretched beyond resting length without being damaged
24. generates tension by a pulling force
