Yes. you can have a Meningioma of the Optic Nerve.
The Optic Nerve (one of the Cranial Nerves) is enclosed by three sheaths that are continuous with the three layers of cranial meninges (dura, arachnoid, and pia). The central artery and vein of the retina pass through these meningeal sheaths and are included in the distal part of the optic nerve.
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
an acoustic neuroma (tumor of the cranial nerve 8).
The vagus nerve is the 10th cranial nerve, also known as cranial nerve X.
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.
Cranial and Spinal Cavities
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
Cranial Nerve 2 - Optic Nerve
The second cranial nerve is the optic nerve.
Nerve X, Vagus
The vestibulocochlear cranial nerve controls hearing.
