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
The only two cranial nerves that are completely sensory are numbers?
The only two cranial nerves that are completely sensory are the olfactory nerve (I) for smell and the optic nerve (II) for vision.
Where the optic nerve connects to the eye is called?
The point where the optic nerve connects to the eye is called the optic disc, or blind spot. This area lacks photoreceptors, meaning it does not detect light, which is why it is referred to as the blind spot. The optic disc is located on the retina and serves as the exit point for the optic nerve fibers that carry visual information 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.
What term describes the region in the eye where the nerve endings of the retina gather to form the optic nerve?
The term for the region in the eye where the nerve endings of the retina gather to form the optic nerve is the "optic disc" or "optic nerve head." This disc is also known as the blind spot since it lacks photoreceptors, making it insensitive to light.
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.
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 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.
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.
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.
If you have a blind spot in your eye because your optic nerve has to connect to your brain somewhere Where?
Retina
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 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.
The only two cranial nerves that are completely sensory are numbers?
The only two cranial nerves that are completely sensory are the olfactory nerve (I) for smell and the optic nerve (II) for vision.
