Where does the optic nerve leave the eye?
The optic nerve exits the retina at the optic disc, otherwise known as the "blind spot".
Which term describes the region in the eye where the nerve endings of the retina gather to form the optic nerve?
The term is "optic disc" or "optic nerve head." This is the point in the eye where the optic nerve exits and carries visual information to the brain.
Is Optic chiasm the blind spot of eye?
No. The blind spot in the eye is the optic disc, the point where the optic nerve meets the retina. At this point, there are no photoreceptors, so no detection of vision. The optic chiasm is the place near the brain where the optic nerves cross over.
What you see is carried to the occipital lobe by the?
optic nerve (at the back of the eye) which then crosses at the optic chiasm. From this point, the optic tracts travel to the lateral geniculate nucleus, and then on to the visual cortex in the occipital lobe.
What is the function of the optic disk in the eye?
Optic disc:The optic disc is also called the blind spot. There are no receptors in this part of the retina. This is where all of the axons of the ganglion cells(last neurons before optic nerve) exit the retina to form the optic nerve.
What does optic chiasm mean literally?
Optic chiasm literally means "crossing of the optic nerves." It is the point in the brain where optic nerve fibers from each eye partially cross over to the opposite side of the brain, allowing visual information to be processed.
What is the function of the blind spots?
It is not a function, it is where the optic nerve connect from the eye to the brain. Because of this there are no photo-receptors at that point.
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.
What is the Motor point of muscle?
Motor Point is located where the moter nerve enters the muscle. It is where the muscle is most electically exciteable.
How does the light travel to your brain?
Light enters the eye through the cornea and passes through the lens, which focuses it onto the retina. The retina converts the light into electrical signals that are transmitted through the optic nerve to the brain's visual cortex, where they are interpreted as images.
Does the Optic disc have rods or cones?
The optic disc does not contain any rods or cones. It is the point on the retina where the optic nerve exits the eye, and thus lacks photoreceptor cells like rods and cones which are responsible for detecting light.
What is the motor point of a nerve?
The nerve motor points is a large muscle mass of shoulders, arms, and legs, striking with leg or hand. Some types of nerve points are superficial peroneal nerve motor point, tibial nerve motor point, common peroneal nerve motor point, and femoral nerve motor point.
