Neuroscience - Descending Motor Pathways

Front 1

originate in the cerebral motor cortex. the cerebellum, or various brainstem nuclei that send axon, into the brain stem and spinal cord to activate cranial or spinal motor neurons

Back 1

upper motor neurons

Front 2

cranial and spinal motor neurons which actually innervate muscles
including alpha and gamma motor neurons of spinal nerves

Back 2

lower motor neurons

Front 3

Upper motor neurons are found entirely within the (CNS or PNS)

Back 3

CNS

Front 4

fibers of lower motor neurons are part of the (CNS or PNS)

Back 4

PNS

Front 5

originates in the cerebral cortex and is distributed to the spinal cord

Back 5

corticospinal tract

Front 6

originates in the red nucleus (nucleus ruber) of the midbrain and is distributed to the spinal cord

Back 6

rubrospinal tract

Front 7

anterior horn of the spinal cord gray matter

Back 7

lower motor neurons of spinal nerves

Front 8

nerves ennervating distal limb musculature are located in the

Back 8

lateral aspects of the anterior horn

Front 9

nerves innervating proximal limb muscles

Back 9

intermediate region

Front 10

medial group of motor neurons innervates the musculature of the appendicular and pelvic girdles
