Where are light receptors located?
Where are light receptors located?
The peripheral receptors for light reside in this part of the eye, responsible for capturing visual information and initiating the process of sight.
What is the optic chiasma?
What is the optic chiasma?
This is the X-shaped structure formed by the crossing of the right and left optic nerves, allowing visual information from both eyes to be processed in both hemispheres of the brain.
What is the optic tract?
What is the optic tract?
This pathway is formed when the uncrossed fibers from one optic nerve combine with the crossed fibers from the other optic nerve after the optic chiasma.

Visual Pathway
- Peripheral receptors for light reside in the retina.
- The structure formed by the right and left optic nerves is the optic chiasm.
- The uncrossed fibers of the optic nerve combine with the crossed fibers at the optic chiasm.
- The termination point of the optic tract is the lateral geniculate nucleus.
- The geniculocalcarine tract, also known as the optic radiation, ends at the visual cortex.
