Document Summary

Overview of the functions of the cerebral cortex. Coordinates movement: motor plan info is sent to cerebellum, also receives position sense information (ex. Muscle stretch fibres), and sends feedback to the cerebellum and motor areas of motor cortex. Middle of cerebellum coordinates middle body movement and walking, while the sides are involved in movements of the limbs arms and legs. Connects all parts of the brain together, including the cranial nerves. Neuron somas scattered throughout brainstem is the reticular formation big role in autonomic functions, and controlling things like respiration, digestion, and lower/higher functions. Long tracts collections of axons connecting cerebrum and brainstem. 2 long tracts that are important: motor (umns), and somatosensory. Cranial nerves most of cranial nerves are attached to the brainstem, doing many things. Subcortical cerebral nuclei that are located deep part of the cerebrum. Internal capsule contains many important pathways, including the corticospinal tract. Corpus collosum connects right and left cerebral hemispheres.
