The right optic tract carries information from the left hand side of both eyes visual field, where-as the right optic nerve carries information solely from the right had eye. After the optic nerves from both eyes perform this partial intersection (in the optic chiasm) they then become known as the optic tract. Hope this helps.

How is the right opic tract anatomically different from the right opic nerve?

Right optic nerve contains the fibers from the retina of the right eye. The right optic tract contains the fibers from the temporal side of the right eye retina and nasal side of the left eye retina. So when the right optic nerve is affected, you will not see with right eye. When the right optic tract is affected, you will lose the left sided vision. That means you will not see, what is happening on the left side of you.

Where on the retina is the blind spot?

It is right in the back of the eye above the divergence of the optic nerve.

Is there a blind spot in the human eye?

Yes, right at the point the optic nerve joins the retina.

Does the left optic nerve carry eye messages only to the left brain side?

No it does not. The left optic nerve carries messages to the right side of the brain. The signals cross over to the other side at the base of the brain.

Pathway from retina to visual cortex?

Retina > Optic Nerve (the 2nd Cranial Nerve) > Optic Chiasma (Change over of Left half of retinal image of both eyes to left and right half of retinal image of both eye to right side) > Lateral Geniculate Nucleus in the mid-brain > Optic radiation > Visual cortex

What if there is something wrong with your visionwhich part of the brain do you think will be affected?

It could be the optic nerve. You should see an ophthalmologist right away.

There is a gland in your brain, right behind the optic nerve. That gland controls puberty stages and how your body grows.

Where is a lesion if there is normal vision in the left eye visual field but there is absence of vision in the right eye visual field?

The lesion will be at the opposite of the absent vision of the eye which is the left eye.Marieb&Hoehn page 578A lesion of the right optic nerve causes a total loss of vision in the right eye. the lesion would be of the left optic nerve is the vision were to be reversed

Absence of vision in right eye visual field?

If you have an absence of vision in the right eye's visual field, you may have a headache coming on. This could also be due to a problem with the optic nerve.

What axon cells form the optic nerve?

Not sure, since I'm working on the same assignment, but I think it is ganglion cells. the gagliano cell axons make a right angle turn at the inner face of the retina then leave the posterior aspect of the eye as the thick optic nerve. page 553 marieb&hoehn axons from the ganglion cells run along the internal surface of the retina and converge posteriorly to form the optic nerve. pg 489 human anatomy 5th ed marieb,mallatt,wilhelm

How are visual signals routed from the eye to the primary visual cortex?

You can better understand the same from diagram. Visual signals from the retina go via optic nerve. One optic nerve from each eye. In the brain, the fibres from nasal side of retina cross to opposite side of the brain. They crosses at optic chiasm. Fibres from temporal side do not cross and go to the same side of the brain. This tract is called as optic tract. This way the fibres from left side of the retinas go to left side of the brain. Fibres from right side of the retinas goes to right side of the brain.

What part of the brain reconstructs visual images?

That answer can be very complicated or very simple. The simple answer is the occipital lobe, or the lobe at the "back" of your brain. A little more complex answer is the visual cortex, which is housed in the cuneus and lingual gyri (divisions) of the occipital lobe, which interpret the image (blend together what the right eye and left eye are seeing individually, as well as keeping the image from being "upside down and backwards"), but not after the different images have passed through the lens, retina, optic nerve, optic chiasm, optic tract, lateral genticulate nuclei, and optic radiations before getting to the cuneous and lingual gyri (in that order), in order to get the images how they need to be (right colors, right blend, right-side-up, right focus, etc). Hope that helps. -A.T. (Resident)

Optic Nerve in relation to the eye?

Are at the back of the eye, they connect the eyes to the brain. They also cross to the opposite side so the information collected by the right eye is processed by the left hemisphere and vice versa

What is the blind spot in the eye's function?

blind spot,small portion of the visual field of each eye that corresponds to the position of the optic disk (also known as the optic nerve head) within the retina. There are no photoreceptors (i.e., rods orcones) in the optic disk, and, therefore, there is no image detection in this area. The blind spot of the right eye is located to the right of the centre of vision and vice versa in the left eye. With both eyes open, the blind spots are not perceived because the visual fields of the two eyes overlap. Indeed, even with one eye closed, the blind spot can be difficult to detect subjectively because of the ability of the brain to "fill in" or ignore the missing portion of the image.The optic disk can be seen in the back of the eye with an ophthalmoscope. It is located on the nasal side of the macula lutea, is oval in shape, and is approximately 1.5 mm (0.06 inch) in diameter. It is also the entry point into the eye for major blood vessels that serve the retina. The optic disk represents the beginning of the optic nerve (second cranial nerve) and the point where axons from over one million retinal ganglion cells coalesce. Clinical evaluation of the optic nerve head is critical in the diagnosis and monitoring of glaucoma and other optic neuropathies that may lead to vision loss.

Function of optic chiasma?

The optic nerves send electrical signals from each eye to meet in the brain at the optic chiasma. Here, the left visual signal from one eye is combined with the other eye and the same goes for the right visual signal. Now the signals split again. The right visual heads for the left brain and the left visual makes its way to the right side of the brain. This way, visual messages from both eyes will reach both halves of the visual cortex. The brain then merges the image into one image which you are looking out at the world with. This partial crossing of the nerve fibers at the optic chiasm (or chiasma) is the reason why we humans have stereoscopic sight and a sense of depth perception.what is the function of the optic chiasm?

How soon should you start steroid treatment for optic neuritis in someone with MS?

This is an interesting question. Many doctors believe that corticosteroids can positively impact MS and can cause reductions of nerve swelling in a shorter timeframe than without. But recent studies have shown that there is very little effect on optic nerve recovery time when using corticosteroids than without. Optic neuritis, whether caused by MS or not, will right itself within a few weeks to a few months. It should be completely cleared in 6 months for most people. There is little need to help it along.
