Neuromuscular Junction

Region where a motor neuron comes in close contact with a muscle cell.

• neurotransmitter

• muscular dystrophy

• muscle tension

• neuromuscular junction

What happens at the neuromuscular junction?

• A sensory neuron communicates with a motor neuron

• An action potential jumps from the muscle to the neuron

• A nerve signal traveling down a motor neuron can jump over to the muscle cell

• Muscle cells contract in response to a sensory neuron

The gap between the nerve cell and sarcolemma is the ____ ___.

• Synaptic cleft

• Neurotransmitter

• Motor unit

• Neuromuscular junction

What is the specific neurotransmitter that stimulates the movement of skeletal muscles?

• GABA
