synaptic cleft 

5

sliding filament theory?

actin slides past myosin and increases overlap thi makes th emsucle fiber shorten 

6

what shortens during sliding filamen ttheory?

i band, distanc ebetween z lines , h zone disaperas 

7

muscle fiber contracts bc of?

nerve impulse 

8

neurotrasmitter junction?

where axopn tewrminal of neuron meets muscle fiber 

9

axon terminal?

distal end of motor neurons axon terminal branch 

10

motor neuron axon terminal has?

calcium channels 

11

synaptic cleft ?

space between axonm terminal and muscle fivber 

12

motor end plate?

portion of sarcolema that forms NMJ 

13

before muscle contraction, ??? goes down the motor neuiron ???, then the nerve impulse arrives at the ???, then calcium channels open  and calcium is ???, then ach goes across ???, then ach binds to ???

acytion potential  , axon , axon terminal , taken in , synaptic cleft, receptors  

14

during excitation contraction, ??? binds to receptors and ??? starts, then ??? and k are taken in, then ??? goes across sarcolema and ??? is released, then ca binds to ???

ach , depolorization , na, action potential, ca , troponin 

15

during contraction, ??? form cross bridges and myosin heads engage in a ???, then acltin slides across ???, then myosin head ???

myosin heads , power storke, myosin, detachges
