Term | Definition |
---|---|
Reticular Formation | a nerve network in the brainstem that plays an important role in controlling arousal |
Corpus Callosum | the large band of neural fibers connecting the two brain hemispheres and carrying messages between them |
Temporal Lobe | a region of the cerebral cortex responsible for hearing and language |
Brainstem | the oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull; is responsible for automatic survival functions |
Brain | the mass of nerve tissue that is the main control center of the nervous system |
Midbrain | a small part of the brain above the pons that integrates sensory information and relays it upward |
Cerebral Cortex | the intricate fabric of interconnected neural cells covering the cerebral hemispheres; the body's ultimate control and information processing center |
Insula | regions of cortex located at the junction of the frontal and temporal lobes |
Medulla Oblongata | part of the brainstem that controls vital life-sustaining functions such as heartbeat, breathing, blood pressure, and digestion |
Cerebellum | a large structure of the hindbrain that controls fine motor skills |
Frontal Lobe | a region of the cerebral cortex that has specialized areas for movement, abstract thinking, planning, memory, and judgement |
Occipital Lobe | a region of the cerebral cortex that processes visual information |
Cerebral Hemispheres | the two sections of the cortex on the left and right sides of the brain |
Parietal Lobe | a region of the cerebral cortex whose functions include processing information about touch |
Cerebrum | area of the brain responsible for all voluntary activities of the body |
Pons | a brain structure that relays information from the cerebellum to the rest of the brain |
Spinal Cord | nerves that run up and down the length of the back and transmit most messages between the body and brain |
