| Medulla oblongata | Continuation of spinal cord. All ascending/descending tracts pass through. Vital centers for heartbeat, blood vessel diameter, breathing, etc. |
| Medulla oblongata | Descending motor impulses cross at the pyramids; ascending sensory impulses cross on the dorsal aspect. |
| Pons | Connects the 2 sides of the cerebellum with each other, connects medulla with midbrain. Additional centers for breathing. |
| Midbrain | Sends motor impulses to pons; sends sensory impulses from spinal cord to thalamus. Some coordination of muscle movements. |
| Thalamus | Relays all sensory input to the proper part of the cerebral cortex. Crude interpretation of some sensory input. |
| Hypothalamus | Controls & integrates many functions of the autonomic nervous system. Controls pituitary gland. Essential to maintaining homeostasis. |
| Cerebrum | Largest part of the human brain. Center of conscious thought, sensory interpretation, & motor control. |
| Frontal lobe of cerebral cortex | Voluntary control of skeletal muscle; center of personality & higher mental functions. |
| Parietal lobe of cerebral cortex | Conscious perception of touch, pressure, pain, vibration, temperature & taste. |
| Occipital lobe of cerebral cortex | Vision |
| Temporal lobe of cerebral cortex | Hearing & smell |
| Medulla, pons, midbrain | 3 parts of the brain stem |
| Thalamus & hypothalamus | 2 parts of the diencephalon |
| Frontal, parietal, occipital, temporal | 4 lobes of cerebral cortex |
| Cerebellum | Regulates posture, balance, coordination of muscle movements. |
