| Cerebral cortex | Made up of lobes, composed of mainly dendrites and cell bodies of neurons |
| Cerebrum interior | composed of mainly white matter |
| Cerebrum (interior) Tracts | nerve fibers arranged in bundles |
| Cerebrum (interior)Basal Nuclei | Islands of gray matter regulate automatic movements and posture |
| Functions of the Cerebrum | Mental processes of all types, including sensations, consciousness, memory, and untary control of movements |
| Spinal Cord (central nervous system) | Columns of white matter composed of bundles of myelinated nerve fibers, form the outer portion of the H-shaped core of the spinal cord, bundles of axons called tracts |
| Spinal Cord (central nervous system)interior | composed of gray matter made up of mainly of neuron dendrites and cell bodies |
| Spinal Cord (central nervous system) Functions | the primary center for all spinal cord reflexes, sensory tracts conduct impulses to the brain, and motor tracts conduct impulses from the brain |
