The special signifies that this fibre type is found in nerves related to the special senses which include vision and hearing. This therefore relates to the optic nerves (cranial nerve II) and the auditory/vestibular systems which are the vestibulocochlear nerves (cranial nerve VIII).

This fibre type is commonly found in sensory nerves to organs and to sensory tissues related to chemicals. These include fibres found in the glossopharyngeal nerves (cranial nerve IX) and the vagus nerves (cranial nerve X).
