Question

What does the optic tract contain?

Answer 1

Hint: The optic tract is an extension of the optic nerve located in the brain. It starts at the area where information from the left eye and right eye cross to create a complete visual picture.

Complete answer:
The optic tract is originally composed of two separate tracts: the left optic tract and the right optic tract. The left optic tract carries the information from temporal retinal fibers from the left eye and nasal retinal fiber from the right eye. The right optic tract transfers the information from the temporal retinal fibers from the right eye and nasal retinal fibers from the left eye.

The optic tract transfers retinal information relating to the whole visual field. Specifically, the left optic tract correlates to the right visual field, while the right optic tract corresponds to the left visual field.
There is a difference between the optic nerve and the optic tract, the key difference between the Optic Nerve and the Optic tract is that the Optic nerve is the nerve that connects your eye to the brain while the Optic tract is a part of the visual system of our brain.

The optic nerve is formed by the convergence of axons arising from the retinal ganglion cells. These cells in return receive impulses from the photoreceptors cells of the eye (the rods and cones). After its formation, the nerve leaves the bony orbit via the optic canal, a passageway through the sphenoid bone.

Note:
The key difference between Optic Nerve and the Optic tract is that the Optic nerve is the nerve that connects your eye to the brain while the Optic tract is a part of the visual system of our brain. Eyes are organs of our visual system
