Their afferents drain multiple surfaces, most of which are lateral in origin. A specific example would be the lateral portions of the eye's bulbar and palpebral conjunctiva as well as the skin adjacent to the ear within the temporal region. The efferents of these nodes pass to the superior deep cervical glands.
The preauricular nodes glands will present with marked swelling in viral conjunctivitis.[1]
