Question #690
Considering innervation of the external ear, which of the following statements is correct?
The external ear is innervated via a number of different nerves and is particularly poorly defined, when considering the auricle:
- Anterior and superior walls of the external acoustic meatus – auriculotemporal nerve
- Inferior and posterior walls of the external acoustic meatus – auricular branch of the vagus nerve
- Helix, anti-helix,lobule - Greater auricular nerve
- Upper cranial surface - Lesser occipital nerve
- Concavity of concha and posterioreminentia - Auricular branch of the vagus
- Tragus, crus of helix - Auriculotemporal nerve
- Facial nerve, fibres picked up by auricular branch of the vagus nerve making it difficult to determine the exact origin.
