In this picture the branches of the facial nerve (CN VII) are in yellow and are pictured over the facial muscles.

In all my research I have never found two identical pictures showing the exact route of the facial nerve. Because of this I have chosen the nicest looking picture (a lot of them are just gross).
TEMPORAL – Top branch going towards the forehead AND under the eye works the raising of the eyebrows, wrinkling of the forehead and helps to gently close your eyes.
ZYGOMATIC – Next branch going towards your nose also goes underneath your eye and enables you to tightly close you eyes.
BUCCAL – Branch going towards the region above the lips produces your smile raising the corners of the mouth and your upper lip.
MANDIBULAR – Branch that goes to the region below the lips and controls all of the expressions that you make with your chin.
CERVICAL – Branch that goes down the neck and controls Platysma, the cords that you can make protrude in your neck. (see “My Progress”)
