====General Somatic Afferent (GSA)====

This type of fibre is used in the majority of basic senses including temperature, touch and pain. These fibres mainly supply sensation to various areas of the head including to the skin and face via the trigeminal nerve (cranial nerve V); to the skin of the external ear via the trigeminal nerve (cranial nerve V), the facial nerve (cranial nerve VII), the glossopharyngeal nerve (cranial nerve IX) and via the vagus nerve (cranial nerve X); to the mucosae of the oral cavity via the trigeminal nerve (cranial nerve V) and to the meningies of the brain via the trigeminal nerve (cranial nerve V) and the vagus nerve (cranial nerve X).

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).
