Second cranial nerve; conveys visual information from the retina to the brain; carries the axons of the retinal ganglion cells which sort at the optic chiasm and continue via the optic tracts to the brain; the largest projection is to the lateral geniculate nuclei; other important targets include the superior colliculi and the suprachiasmatic nuclei; though known as the second cranial nerve, it is considered part of the central nervous system.CRISP ThesaurusNational Institutes of Health, 2006
-
The 2nd cranial nerve which conveys visual information from the RETINA to the brain. The nerve carries the axons of the RETINAL GANGLION CELLS which sort at the OPTIC CHIASM and continue via the OPTIC TRACTS to the brain. The largest projection is to the lateral geniculate nuclei; other targets include the SUPERIOR COLLICULI and the SUPRACHIASMATIC NUCLEI. Though known as the second cranial nerve, it is considered part of the CENTRAL NERVOUS SYSTEM.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021

The nerve that carries messages from the retina to the brain.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021
-
Optic nerve, second cranial nerve, which carries sensory nerve impulses from the more than one million ganglion cells of the retina toward the visual centres in the brain. The vast majority of optic nerve fibres convey information regarding central vision. The optic nerve begins at the optic disk...Encyclopedia Britannica, Inc., 2020
