In neuroanatomy, the optic nerve, also known as the second cranial nerve, cranial nerve II, or simply CN II, is a paired cranial nerve that transmits visual information from the retina to the brain.
Apr 11, 2024 · The optic nerve is the second of 12 cranial nerves, which get their name from how they all directly connect to your brain. Each cranial nerve is a left- and right-sided pair (but experts commonly refer to them like it’s just a single nerve).
May 27, 2023 · It is a bundle of nerve cells that transmits sensory information for vision in the form of electrical impulses from the eye to the brain. The optic nerve has been studied heavily because it is a direct extension of the brain. Anatomy. The optic nerve is mainly made up of the axons (nerve fibers) of the retinal ganglion cells from the retina.
Aug 16, 2023 · The optic nerve head is a unique part of CN II in that it marks an important point of vascular, geometric and tonometric transition. At the optic nerve head, the optic nerves are moving to the relatively low pressure space of the retro-orbital region from the much higher intraocular pressure zone.
Feb 20, 2024 · The optic nerve is part of the eye, the central nervous system (CNS), and one of the 12 cranial nerve pairs. 1 It’s also known as the second cranial nerve or cranial nerve II. The optic nerve is responsible for transmitting visual information to the brain for interpretation. This enables clear vision. Each eye consists of one optic nerve.
Nov 7, 2022 · The optic nerve is the second cranial nerve (CN II) responsible for transmitting visual information. The optic nerve contains only afferent (sensory) fibers, and like all cranial nerves is paired.
Dec 16, 2014 · The optic nerve (CN II) is the second cranial nerve, responsible for transmitting the special sensory information for vision. It is developed from the optic vesicle , an outpocketing of the forebrain.
