it is located in the brain and goes from the retina (back of the eye) to center of the brain.
for more details research OPTIC NERVE or CN 2 (for short)
Cranial Nerve 2 - Optic Nerve
Cranial nerve number 2 is the optic nerve, responsible for most of the sensation of sight.
Occulomotor nerve (CN III) is located between the midbrain and pons.
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
impulses travel down cranial nerve 2 to what lobe
The vagus nerve is the 10th cranial nerve, also known as cranial nerve X.
Olfatory is the CN 1, Optic nerve is the Second.
vestibulocochlear nerve
Smell impulses are carried by the cranial nerve called the olfactory nerve (cranial nerve I). It is responsible for transmitting information about odors from the nose to the brain.
The optic nerve (cranial nerve II) is not involved in taste, as its primary function is vision. Taste is primarily mediated by the facial nerve (cranial nerve VII), glossopharyngeal nerve (cranial nerve IX), and vagus nerve (cranial nerve X).
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
The second cranial nerve is the optic nerve.
