Motor pathways consist of an upper motor and lower motor neuron.

Here's a step-by-step explanation:

1. The upper motor neuron: This neuron has its cell body in the cerebral cortex or brainstem. It sends its axon down to the spinal cord. The upper motor neuron connects with the lower motor neuron at the level of the spinal cord where the nerve impulse needs to exit to reach its target muscle.

2. The lower motor neuron: This neuron has its cell body in the spinal cord. It sends its axon out of the spinal cord and into the peripheral nervous system. The axon of the lower motor neuron then connects with the muscle that needs to be innervated.

So, in summary, the motor pathway consists of two neurons - the upper motor neuron and the lower motor neuron. The upper motor neuron sends signals from the brain down to the spinal
