Yes there is a possibility to be blind. It is called functional blindness attributed to a natural "instinctive protest against further danger" (W. B. Pillsbury).

The axons of the retina culminate in what nerve?
the axons of the retina culminate in the optic nerve which forms a blind spot on the retina
What happens when the optic nerve is pinched or cut?
You would go blind, because the optic nerve would then be unable to transmit signals from the eye to the brain.
Does the optic nerve pass through the foramen ovale?
The natural blind spot (scotoma) is due to lack of receptors (rods or cones) where the optic nerve and blood vessels leave the eye. It is where the optic nerve leaves the retina not enter it. The optic disk or blind spot is where the optic nerve leaves the eye; you cannot use that field of vision because the optic nerve is there.
Is transcutaneous electrical nerve stimulation safe?
It is nonaddictive and completely safe
Area of the retina that lacks rods and cones?
The retina is filled with rods and cones- except for one spot. This place that lack rods and cones is called the blind spot, which can be found by covering up one eye and looking at something with the other. Out of the corner of your uncovered eye, you will will see something disappear. We don't realize it on a daily basis because our brain fills in the empty spot. The blind spot is located near the optic nerve and is about 2mm wide.
The axons of the retina culminate in what nerve?
the axons of the retina culminate in the optic nerve which forms a blind spot on the retina
Where in the retinas are the blind spots located?
The blind spot of each eye is located where the optic nerve leaves the eye.
Is blind spot only present in human?
No. The blind spot reflects the retinal area where the optic nerve fibres leave the eye ( The Optic Nerve head). So in many animals the blind spot is present though they are not aware of it. Same goes with human.
In the Retina what physical structure results in a blind spot?
optic nerve
Is the blind spot in the eye the optic nerve leaving the eye?
Yep.
Where is the blind spot located?
The blind spot is also called the optic nerve head. It is located on the retina, about 15 degrees horizontal from center vision.
Why do human eyes have a blind spot?
The brain compensates for the blind spot. It compensates for it by taking in what is around the blind spot and using that as a reference to put a picture in the brain of what it thinks should be in the blind spot.
Where does the optic nerve leave the eye?
The optic nerve exits the retina at the optic disc, otherwise known as the "blind spot".
What is the function Blind Spot?
The blind spot does not have or serve a function. The blind spot is cause by a lack of receptors in the location where a person's optic nerve and blood vessels leave the eye.
If you have a blind spot in your eye because your optic nerve has to connect to your brain somewhere Where?
Retina
What happens when the optic nerve is pinched or cut?
You would go blind, because the optic nerve would then be unable to transmit signals from the eye to the brain.
What will happen if you are stabbed with glass in a nerve?
It completely depends on the individual, how hard you're stabbed, etc. If the nerve receptor were completely obliterated, which is unlikely, pain from that nerve shouldn't be felt. Its highly likely the wound would hurt immensely though.
