B)the neuroglia of the motor neuron down the axon, and then from the axon of the neuron to the muscle.
C)the axon of the motor neuron down to the dendrites, and then from the dendrites of the neuron to the muscle.
D)the axon of the motor neuron down to the neuroglia, and then from the neuroglia to the dendrites of the muscle.

When a signal travels from a motor neuron to a skeletal muscle, it starts with an action potential at the dendrites of the motor neuron. This action potential then moves down the axon of the neuron, where it triggers the release of neurotransmitters (such as acetylcholine) at the neuromuscular junction. These neurotransmitters then bind to receptors on the muscle membrane, causing depolarization and contraction of the muscle. Therefore, the nerve signal travels from the dendrites of the motor neuron down the axon, and then from the axon of the neuron to the muscle.
