what is the job of the upper motor neurons
A. to carry motor information from the cortex to CN’s in the brain stem or interneurones that synapses in the ventral horn
B. to carry motor information from the motor cell bodies in ventral horn to skeletal muscles
C. preservation of sensory and motor functions
Preview next quiz:
what is the process of the corticospinal tract
A. to carry unconscious /voluntary motor information from the pre-central gyrus up to, but not including the ventral horn . The track then synapses onto motor spinal nerves that innovate skeletal muscles
B. to descend from corticospinal track and project onto certain cranial nerve nuclei that have motor components. This track controls cranial nerves and lower motor neurons
C. proprioceptors that are located in the skeletal muscles that provide a constant flow of information on the muscles
