29

myo fribril is made up of ???

myoilaments 

30

A motor neuron and all of the skeletal muscle cells it stimulates is called a ???. . The axon of each motor neuron has numerous endings called ???.  The actual gap between an axonal ending and the muscle cell is called a ???. Within the axonal endings are many small vesicles containing a neurotransmitter substance called ?? 

motor unit , axon terminals, synaptic cleft, ACH  

31

When the ________________________ reaches the ends of the axon, the neurotransmitter is released, and it diffuses to the muscle cell membrane, called the _____________________, to combine with receptors there.Binding of the neurotransmitter with muscle membrane receptors causes the membrane to become permeable to sodium, resulting in the influx of sodium ions and ________________________of  the membrane.  

nerve imoulse, sarcolema , depolorization 

32

steps of contraction of muscle ?

ACH is ???. ACH diffuese across ??? and binds to ???, depolarzation and ??? occur. rleases ???. and myofilaments slide past one another, and the cell ??? . As ??? is actively reabsorbed into the sarcoplasmic reticulum. then the muscle cell ??? and leghtehsn
