Nerve Stimulus Excites the Muscle Cell

Nerve Stimulus Excites the Muscle Cell. A muscle cell must receive a stimulus to begin the excitation-contraction coupling Series of events linking electrical signal to muscle contraction Muscle cells can be stimulated by ACh ACh- Acetylcholine- neurotransmitter

The signal for contraction comes down the axon of a motor neuron to the neuromuscular junction.

The signal for contraction comes down the axon of a motor neuron to the neuromuscular junction. When it arrives at the axon terminal, the synaptic vesicles fuse with the membrane and release the neurotransmitter (acetylcholine) into the synaptic cleft.
