the cerebral cortex
The motor neuron cells are all in the brain and the spinal cord.
There is upper motor neuron in spinal cord. There is lower motor neuron in the spinal nerve.
brain and spinal cord
It depends on what part of the brain or spinal cord. If it is in the brain it can cause death or complete paralysis, if it is in the spinal cord e.g. Lower part of the spinal cord you are paralysed from the hips down.

Sensory neurons carry impulses from the sense organs to the brain and the spinal cord . Motor neurons carry impulses from the brain and spinal cord to muscles or glands.
The grey matter on a spinal cord is on the spinal roots.
1 sensory organ - sensory nerves - spinal cord - brain 2 brain - motor nerves - spinal cord - muscles
Introduction. Spinal cord reflexes are simple behaviors produced by central nervous system (CNS) pathways that lie entirely within the spinal cord. The sensory afferent fibers that evoke these reflexes enter the spinal cord and activate spinal motor neurons directly or through a chain of one or more spinal interneurons
No, those are in the brain. The Brain Stem and the Spinal Cord are for reflexes and transmitting nervous messages to the brain.
spinal cord as opposed to the brain
Motor neurons send messages from the brain or spinal cord to the body.
