Question

8) A blind spot in the retina occurs where A) the fovea is located. B) rod cells are clustered to form the macula. C) the optic nerve leaves the eye. D) amacrine cells are located. E) ganglion cells synapse with bipolar cells.

Answer 1

The blind spot in the retina occurs where C) the optic nerve leaves the eye.

Step-by-step explanation:

The correct answer for the given question is C) the optic nerve leaves the eye. The blind spot in the retina occurs where the optic nerve exits the eye. This is because the axons of retinal ganglion cells converge and exit through the back of the eye to form the optic nerve. At this point, there are no photoreceptor cells, creating a blind spot in our visual field.

The optic nerve is the second cranial nerve responsible for transmitting visual information from the retina to the brain. Composed of axons of retinal ganglion cells, it carries electrical signals that encode visual stimuli. The optic nerve plays a vital role in vision, connecting the eye to the visual processing centers in the brain.

Answer 2

option c

Step-by-step explanation:

A natural blind spot also called the optic disc in the eyes occurs where the blood vessels and axons of the ganglion cells leave to form the optic nerve. it is so called because there are no receptors (rods and cones) in this part of the retina. Artificial blind spots can also be formed when something prevents light from getting to the photoreceptors which are the rods and the cones.
