When Mohegan had applied the bark, he freely relinquished to Richard the needle and thread that were used in sewing the bandages, for these were implements of which the native but little understood the use: and, step ping back with decent gravity, awaited the completion of the business by the other.
The neurons of the upper motor neuron system are located in the cerebral cortex (Figure 103.1[1]), basal ganglia (Figure 103.1[2]), cerebellar nuclei (Figure 103.1[3]), red nuclei (Figure 103.1[4), reticular formation (Figure 103.1[5]), and the lateral vestibular nucleus (Figure 103.1[6]).hese axons travel through the brain and brainstem to make contact with the motor neurons in the brainstem and through the brain, brainstem, and spinal cord (Figure 103.1[4]) to make contact with the motor neurons in the anterior horn of the spinal cord.
Although the basal ganglia are a distinct part of the motor system, they appear to work in concert with the pyramidal motor pathwayâthe path that conducts signals for action directly along nerve tracts that descend from the cerebral cortex to the motor neurons that activate skeletal muscles.
