dorsal root ganglia and cranial root ganglia
The motor neuron cells are all in the brain and the spinal cord.
For spinal nerves transmitting general somatic efferent motor information, the answer is the ventral horn.Autonomic nerves have the cell bodies their motor neurons, general visceral efferent, located within ganglia within the periphery.
A second order neuron is the 2nd neuron to carry an order. The order could be a sensory stimulus or a motor stimulus. For e.g. in order to move a muscle, the order for that muscle to contract starts at the cerebral cortex in the somatomotor area. That is the first order neuron. The axon of the 1st order neuron will synapse with the 2nd order neuron at the level of the brain stem, which commonly decussate (crosses over) to the opposite side. In turn, the axon of the 2nd order neuron will descend along the spinal cord tracts where it will synapse with the 3rd order neuron. The 3rd order neuron is located in the ventral horn of the spinal cord, which will exit with the spinal nerve to supply the muscle.
A synapse connects one neuron to another (and a neuron to a muscle cell).The axon hillock at the 'end' of the neuron cell body (soma) initiates a firing of the axon of a neuron.An axon terminal at the end of an axon is the first part of a synapse.If this didn't answer your intended question, please compose it better.
The cell body, called the SOMA, is the main part of the neuron. It is the main metabolic center or region of the neuron. The neuron has 3 parts: DENDRITES (inputs), SOMA (cell body), and AXON (output). The axon is the part which FIRES when sufficient inputs reach it at the axon hillock.
Second order neuron cell bodies reside in the dorsal horn of the spinal cord.
The motor neuron cells are all in the brain and the spinal cord.
It is a cell (neuron) located in the anterior horn of the spinal cord.

gray matter
A neuron cell's job is to send electrical pulses throughout the body in order to coordinate the body's movements and activities.

a neuron is a nerve cell
A neuron is a nerve cell.
autonomic motor neuron that has its body in a peripheral ganglion and projects its (postganglionic) axon to an effector.
The cell body, called the SOMA, is the main part of the neuron. It is the main metabolic center or region of the neuron. The neuron has 3 parts: DENDRITES (inputs), SOMA (cell body), and AXON (output). The axon is the part which FIRES when sufficient inputs reach it at the axon hillock.
