​Corticospinal tract

*i​ncluding the location of the upper motor neurons (i.e., red nucleus, vestibular nucleus, superior and inferior colliculi, or reticular nucleus to the spinal cord) and lower motor neurons

Explain the process of performing motor activity, including the how the cerebellum compares different sources of information in order to control balance & equilibrium and how basal nuclei receives information and outputs information to adjust movements

• Prefrontal cortex, basal nuclei (ganglia), cerebellum, lower motor neurons, medial and lateral pathways, proprioceptors, spinocerebellar pathwayplace

​Clinical case study

A 39-year-old female, lost control while skiing and hit her head on a tree. She regained consciousness en route to the hospital and was agitated and combative. Paramedics observed that she had extreme muscle weakness of her right leg and partial weakness of her right arm. A head CT scan revealed an extensive subarachnoid hemorrhage and surgery to remove large clots from the subarachnoid space was performed immediately immediately.

Two weeks after the surgery, she showed significant improvement in motor function.
