Question

Quizplus · Accepted Answer

The X shape of the optic nerves is called the optic chiasma, where the optic nerves from each eye intersect and partially cross over to the opposite side of the brain. This is where information from the left visual field goes to the right side of the brain, and vice versa. Choice A refers to the cranial nerve X, which is the Vagus nerve responsible for controlling several organs in the body. Choice C refers to the optic disc, which is the spot where the optic nerve exits the eyeball and lacks visual receptors, making it a blind spot. Choice D refers to the macula, which is a small area in the center of the retina responsible for detailed and high-acuity vision.
