chapter 13
Across
- 2. the plasma membrane skeletal muscles are enclosed in
- 4. the gap which separates the axon of one neurone to the dendrite of another
- 5. long cylindrical organelles made of protein and are specialised for muscle contraction
- 7. the thicker filament
- 9. the thinner filament
- 11. maintaining constant internal body conditions
- 14. convert a energy from one form to another
- 16. a type of neurone which connects sensory neurone to motor neurone
- 17. a type of reflex responsible for involuntary blinking of eyelids
- 18. an electrical insulator, allows impulses to 'jump'
- 20. a type of muscle making up the bulk of the body muscle tissue
- 21. a type of sensory receptor, stimulus-chemicals
Down
- 1. enzyme which hydrolyses acetylcholine into acetyl and choline
- 3. contraction speed of skeletal muscle
- 6. a type of motor system in the NS responsible for fight or flight
- 8. a type of neurotransmitter which prevents an action potential being triggered
- 10. are actively transported out of axon during resting potential
- 12. a type of nervous system under conscious control
- 13. a type of synapse which uses the NT acetycholine
- 15. is stored in muscle, acts as a reserve supply of phosphate
- 19. the are of the brain responsible for posture+balance
