How is the light optic tract anatomically different from the right optic nerve?
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.
What is the function of the optic chiasm?
The optic chiasma is in front of the pituitary gland where optic nerve fibers pass to the brain. The function of the optic chiasma is to relay electric signals as they pass from the optic nerve to the brain.
What is the blind spot of the retina?
That is the place on the retina where the optic nerve exits the eye; there are no light receptors there. In your left eye it is left of the center of the field of vision, and in the right eye it is right of the center of the field of vision. So physically, they are both inside of center. It is fun to demonstrate the blind spots and it is easily done.
Why does the optic nerve cause the blind spot?
The optic nerve (also known as cranial nerve II) is a continuation of the axons of the ganglion cells in the retina. There are approximately 1.1 million nerve cells in each optic nerve. The optic nerve, which acts like a cable connecting the eye with the brain, actually is more like brain tissue than it is nerve tissue. As the optic nerve leaves the back of the eye, it travels to the optic chiasm, located just below and in front of the pituitary gland (which is why a tumor on the pituitary gland, pressing on the optic chiasm, can cause vision problems). In the optic chiasm, the optic nerve fibers emanating from the nasal half of each retina cross over to the other side; but the nerve fibers originating in the temporal retina do not cross over. From there, the nerve fibers become the optic tract, passing through the thalamus and turning into the optic radiation until they reach the visual cortex in the occipital lobe at the back of the brain. This is where the visual center of the brain is located. The visual cortex ultimately interprets the electrical signals produced by light stimulation of the retina, via the optic nerve, as visual images. A representation of parasympathetic pathways in the pupillary light reflex can be seen here: parasympathetic response. The beginning of the optic nerve in the retina is called the optic nerve head or optic disc. Since there are no photoreceptors (cones and rods) in the optic nerve head, this area of the retina cannot respond to light stimulation. As a result, it is known as the "blind spot," and everybody has one in each eye. The reason we normally do not notice our blind spots is because, when both eyes are open, the blind spot of one eye corresponds to retina that is seeing properly in the other eye. Here is a way for you to see just how absolutely blind your blind spot is. Below, you will observe a dot and a plus. This The End The optic nerve causes a blind spot because it is a continuation of the axons of the ganglion cells in 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 nerve contains sensory nerves from both eyes?
optic tract

What is a difference between optic nerve and auditory nerve?
Optic nerve is found in the eye which sends the nerve impulses from the eye to the brain. The auditory nerve is present in the ear and sends the nerve impulses from the ear to the brain. They both have the same functions though they're present in different places.

Trace the pathway of nerve impulses from the photoreceptors in the retina to the visual cortex of the brain?
The rods and the cones transduce light waves into neural impulses that pass from the bipolar cells to the ganglion cells, whose axons from the optic nerve beyond the retinal wall of each eye. At the optic chiasm, the two optic nerves come together, and some of the nerve fibers from each eye cross to the opposite side of the brain. They synapse with neurons in the thalamus, which transmit the neural impulses to the primary visual cortex.

OpTic MiDNiTE is not a what. She's a who. OpTic MiDNiTE is a member of OpTic Gaming. She is a female gamer who is interested in both sexes (boy and girl).
What cranial nerve is totally sensory in function?
here's a useful mnemonic that I used in medical school:1. Some - olfactory (sensory)2. Say - optic (sensory)3. Marry - oculomotor (motor)4. Money - trochlear (motor)5. But - trigeminal (both)6. My - abducens (motor)7. Brother - facial (both)8. Says - vestibulocholear (sensory)9. Big - glossopharyngeal (both)10. Boobs - vagus (both)11. Matter - accessory (motor)12. More - hypoglossal (motor)
