Question

Nerve fibers from all regions of the retina converge on the ___ and exit the eye by way of the optic nerve.

Answer 1

Answer:Nerve fibers from all regions of the retina converge on the optic disc and exit the eye by way of the optic nerve.

Explanation: The eye is part of the sense organs which is used for visual purposes. It is made up if different parts that aid to achieve its visual functions, they include:

Lens, retina, optic nerve, cornea and many among others.

The images that are reflected through the len on the retina is converted into a set of electrical signals, and these signals are transmitted to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain.

The optic nerve is made up of ganglion cell axon while the optic disc represents the beginning of the optic nerve and is the point where the axons of retinal ganglion cells come together. I hope this helps, thanks.

Answer 2

Answer: Optic Disc

Explanation:Optic Disc is a portion of the eye,it can be seen as black spot on the eye,it doesn't contain rods. Optic disc is the point of exit for optic nerve.

The optic disc is also known as the optic nerve Head,it is made up of connective and elastic tissue, it is the passage to the nerve fibre bundles and retinal blood vessels it also maintain intra-ocular pressure against a gradient between the intra-ocular and extra-ocular spaces.
