Question: 1 / 400

Which part of the body does the facial nerve primarily serve?

Arm and hand

Face

The facial nerve primarily serves the face, playing a crucial role in controlling the muscles responsible for facial expressions. It innervates various muscles that allow for movements such as smiling, frowning, and raising eyebrows. In addition to motor functions, the facial nerve is involved in the sensation of taste from the anterior two-thirds of the tongue and provides some control over the tear and salivary glands. This comprehensive service to facial features and functions makes the face the primary area served by the facial nerve. Other parts of the body, such as the arm, hand, lower legs, and back, are innervated by different nerves that serve those specific regions, underscoring the unique role the facial nerve plays in facial activities and expressions.
