auricular nerve

Any of three nerves, the great auricular nerve, the posterior auricular nerve, or the auricular branch of the vagus nerve (CN X). The great auricular nerve is a sensory branch of the cervical plexus composed of axons from spinal cord segments C2–C3; it innervates the skin and fascia behind the ear, on the lower part of the pinna of the ear, and over the angle of the jaw. The posterior auricular nerve is a motor branch of the facial nerve (CN VII) that innervates the posterior and intrinsic auricular muscles. The auricular branch of the vagus nerve is a sensory nerve emerging from the superior ganglion of the vagus nerve, joined by branches from the glossopharyngeal (CN IX) and facial nerves, and innervating the lower part of the tympanic membrane and the floor of the external auditory canal.
