Structure of the brain and spinal cord diagram with labeled parts and their functions, including the lobes of the cerebrum.

- cerebellum: coordinates balance and action
- medulla oblongata: controls breathing, heart rate, and blood pressure
- thalamus: coordinates incoming information
- hypothalamus: controls secretions of pituitary gland
- corpus callosum: thick fibrous band; connects two hemispheres
- pons: links cerebral cortex to cerebellum and cerebrum
- spinal cord: main nerves of CNS extend down from brain
- cerebrum: largest part; controls voluntary action
- pituitary gland: endocrine gland—secretes many hormones

The frontal lobes control some body movements, reasoning, judgment and emotions. The sense of vision is located in the occipital lobe. The sense of hearing is interpreted in the temporal lobes. The parietal lobes interpret sensations such as pain, pressure, touch, hot and cold.
