chapter 13

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

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
