There are 12 pairs of nerves that directly arise from the brain and stem. There are others that arise in pairs from the spinal cord.
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
The second cranial nerve is the optic nerve.
The nerves involved in diplopia include three cranial nerves: the oculomotor nerve (third cranial nerve), the abducens nerve (sixth cranial nerve), and the trochlear nerve (fourth cranial nerve).
Cranial nerve 4 (IV) is the trochlear nerve.
cranial nerve I: olfactory:smell cranial nerve II:optic:vision cranial nerve III: oculomotor: 4 of 6 eye muscles cranial nerve IV: trochlear: cranial nerve V: Trigeminal cranial nerve VI: Abducens cranial nerve VII: Facial cranial nerve VIII: Vestibulochlear: hearing cranial nerve IX: Grosspharnxgeal: saliva formation cranial nerve X: Vegus cranial nerve XI: Acessory Spinal: trapizious movement cranial nerve XII: Hypoglosseal: toungue movement
Cranial Nerve 2 - Optic Nerve
The olfactory nerve, or 1st cranial nerve.
Nerve X, Vagus
Cranial nerve II
The vestibulocochlear cranial nerve controls hearing.
The cranial nerve responsible for hearing and equilibrium is vestibulocochlear nerve (CN VIII). It originates from between the pons and medulla.
The Facial Nerve or Cranial Nerve VII is the nerve involved with Bell's Palsy.
