| Posterior Auricular | Extends to the muscles behind and below the ear: |
| Temporal | Extends to the muscles of the temple, the side of the forehead, the eyebrow, eyelid and upper cheek: |
| Buccal | Extends to the muscles of the mouth: |
| Marginal Mandibular | Extends to the muscles of the chin and lower lip: |
| Cervical Cutaneous | Extends to the muscles on the side of the neck: |
| Greater Occipital | Extends up the back of the scalp to the top of the head: |
| Lesser Occipital | Extends into the muscles at the back of the skull: |
| Greater Auricular | Extends into the side of the neck and external ear: |
| Cervical | Extends into the side and front of the neck to the breastbone: |
| Accessory | Also known as the 11th cranial nerve; controls the sternocleidomastoid and trapezius muscles: |

| Ophthalmic Branch | Main nerve branch to the top 1/3 of the face: |
| Maxillary Branch | Main nerve branch to the middle 1/3 of the face: |
| Mandibular Branch | Main nerve branch to the lower 1/3 of the face: |
| Autonomic Nervous System | Responsible for all involuntary body functions. |
| Peripheral Nervous System | Composed of sensory and motor nerves that extend from the brain and spinal cord to other parts of the body: |
| Axons | Take information away from the cell body in the form of nerve impulses: |
| Dendrites | Bring information to the cell body: |
