Question 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 ???.

Answer 30

motor unit , axon terminals, synaptic cleft, ACH

Question 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
