1) optic nerves, optic tracts, optic chiasma, optic radiations, thalamus, visual cortex
2) optic nerves, optic chiasma, optic tracts, thalamus, optic radiations, visual cortex
3) optic nerves, thalamus, optic chiasma, optic tracts, optic radiations, visual cortex
4) optic chiasma, optic nerves, optic tracts, thalamus, optic radiations, visual cortex

Answer 1

The correct sequence of structures in the visual pathway is optic nerves, optic chiasm, optic tracts, thalamus, optic radiations, visual cortex.

Step-by-step explanation:

The correct sequence of structures of the visual pathway to the visual cortex is:

1. Optic nerves
2. Optic chiasm
3. Optic tracts
4. Thalamus
5. Optic radiations
6. Visual cortex

First, the optic nerves transmit visual information from the eyes to the optic chiasm.

Then, at the optic chiasm, some of the nerve fibers cross over to the opposite side.

Next, the crossed and uncrossed fibers enter the optic tracts and travel to the thalamus.

From the thalamus, the visual information is relayed to the visual cortex through the optic radiations.

Finally, the visual cortex, located in the occipital lobe of the brain, processes and interprets the visual information.
