The motor neuron cells are all in the brain and the spinal cord.
For spinal nerves, the general somatic efferent motor neurons have their cell bodies located in the ventral horn of the spinal cord (sometimes also called the anterior horn).Some of your cranial nerves also have motor neurons located in various nuclei of the brainstem.
The cell body of a motor neuron is located in the spinal cord or brainstem. It contains the nucleus which regulates the activities of the neuron and plays a key role in transmitting signals to control muscle movement.
A Betz cell is a large pyramidal cell neuron located within the fifth layer of the grey matter in the primary motor cortex.
The nucleus of a neuron is typically located in the cell body, also known as the soma. It is located towards the center of the neuron, where it functions to control the activities of the cell and contains the genetic material needed for cellular functioning.
In vertebrates, the term motor neuron (or motoneuron) classically applies to neurons located in the central nervous system (or CNS) that project their axons outside the CNS and directly or indirectly control muscles. The motor neuron is often associated with efferent neuron, primary neuron, or alpha motor neurons.Source:Wikipedia (search Motor neuron, to read more).
