Question 21 pts

The axons of upper motor neurons leave the cerebral cortex and enters the                           [ Select ]                       ["Lateral corticospinal tract", "Internal capsule"]         , which is made up of white matter. The axons continue to descend into the                            [ Select ]                       ["brainstem", "spinal cord"]         where they cross midline at a region called the                           [ Select ]                       ["Medial lemniscus", "Decussation of pyramids"]         .

After crossing midline, the axon of the upper motor neuron continues its descent in the lateral portion of the spinal cord called the                            [ Select ]                       ["Anterolateral tract", "Lateral corticospinal tract"]         . Once the upper motor neuron reaches its intended lower motor neuron, the upper motor neuron synapses onto a                           [ Select ]                       ["upper motor neuron", "lower motor neuron"]         in the                            [ Select ]                       ["Dorsal Horn", "Dorsal root", "Ventral horn", "Ventral root"]         of the spinal cord.

Explanation / Answer

# upper motor neurons are located in "precentral gyrus/frontal lobe"

# The axons of upper motor neurons leave the cerebral cortex and enters the"internal capsule" which is made of white matter.The axon continue to descend into the "brainstem" where they crosses midline at region called the "Decussation of pyramids"

#After crossing midline,the axon of the upper motor neuron continues its descent in lateral portion of spinal cord called "lateral corticospinal tract" Once the upper motor neuron reaches its intended lower motor neuron.the upper motor neuron synapses onto "lower motor neuron" in the "Dorsal horn"

#Each muscle fiber is innervated by multiple lower motor neurons:False

#White matter of spinal cord.
