Question

in the corticospinal pathway, the neuron that exits the spinal cord by a spinal nerve is called the ________ neuron. upper sensory pyramidal lower sensory lower motor upper motor

Explanation:

In the corticospinal pathway, the upper motor neuron has its cell - body in the motor cortex and synapses with the lower motor neuron. The lower motor neuron exits the spinal cord via a spinal nerve to innervate skeletal muscles. Sensory neurons are involved in carrying sensory information (not motor output as in the corticospinal pathway for voluntary movement). Pyramidal neurons are a type of neuron in the cerebral cortex (many upper motor neurons are pyramidal neurons, but the key here is the neuron that exits the spinal cord).

Answer:

lower motor
