what is the structure and function of a motor neuron?
A motor neuron, sometimes combined into the singular term motoneuron, is a nerve cell. Its basic structure includes a receptor on one end and a transmitter on the other, connected by an elongated body called the axon, some of which can be 39 inches (1m) long in humans.
The function of a motor neuron is to carry an electrical signal to a muscle, triggering it to either contract or relax.
