Watch this video (http://openstaxcollege.org/l/basalnuclei1) to learn about the basal nuclei (also known as the basal ganglia), which have two pathways that process information within the cerebrum. As shown in this video, the direct pathway is the shorter pathway through the system that results in increased activity in the cerebral cortex and increased motor activity. The direct pathway is described as resulting in disinhibition of the thalamus. What does disinhibition mean? What are the two neurons doing individually to cause this?
Watch this video (http://openstaxcollege.org/l/motorpathway) to learn more about the descending motor pathway for the somatic nervous system. The autonomic connections are mentioned, which are covered in another chapter. From this brief video, only some of the descending motor pathway of the somatic nervous system is described. Which division of the pathway is described and which division is left out?
Which of the following is not part of the corticospinal pathway? cerebellar deep white matter midbrain medulla lateral column

The primary motor area receives inputs arising from all the followingcenters, except :-a- basal gangliab- cerebellumc- hypothalamusd- thalamus
Communication between the motor cortex and the spinal cord is likely to be mediated by fiber tracts. commissural O corpus callosum O projection association none of the answers. 身
