Anatomy Of Optic Nerve

The nerve that sends sensory information from the eye to the brain anatomy. Known to the greek fathers of anatomy as nervus optikus the optic nerve has the responsibility of transmitting special afferent impulses of light to the brain.

Anatomy Of Optic Nerve And Its Clinical Significance

Our blind spot is caused by the absence of specialized photosensitive light sensitive cells.

Anatomy of optic nerve. The optic nerve is mainly made up of the axons. The job of the optic nerve is to transfer visual information from the retina to the vision centers of the brain via electrical impulses. The optic nerve begins at the optic disk.

The optic nerve is made of ganglionic cells or nerve cells. Glaucoma refers to a group of diseases that may cause damage to. The vast majority of optic nerve fibres convey information regarding central vision.

The head of optic nerve is around 1 mm long and about 15 mm in diameter. The optic nerve produces all sorts of visual information. The key points of the on are the optic nerve head and chiasm.

The optic nerve on is constituted by the axons of the retinal ganglion cells rgcs. The horizontal diameter is smaller than the vertical diameter. The identity of cranial nerve ii cn ii also known as the optic nerve predates galenic anatomy.

The anatomy of the optic nerve can be divided into four different sections. These axons are distributed in an organized pattern from the soma of the rgc to the lateral geniculated nucleus where most of the neurons synapse. 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.

It consists of over one million nerve fibers.
