What is the path of the visual neural pathway from the retina?
- Cornea -> LGN -> retina
- Iris -> retina -> optic nerve -> LGN
- Lens -> retina -> optic nerve -> LGN
- Retina -> optic nerve -> LGN -> visual cerebral cortex (correct)
What is the correct order of the visual pathway from the retina to the visual cortex?
What is the correct order of the visual pathway from the retina to the visual cortex?
- Retina → Optic Tract → Optic Nerve → Optic Chiasm → Lateral Geniculate Nucleus → Optic Radiation → Visual Cortex
- Retina → Optic Radiation → Optic Tract → Optic Nerve → Lateral Geniculate Nucleus → Optic Chiasm → Visual Cortex
- Retina → Lateral Geniculate Nucleus → Optic Radiation → Optic Tract → Optic Nerve → Optic Chiasm → Visual Cortex
- Retina → Optic Nerve → Optic Chiasm → Optic Tract → Lateral Geniculate Nucleus → Optic Radiation → Visual Cortex (correct)
What is the relationship between the visual field and retinal fields in the visual cortex?
What is the relationship between the visual field and retinal fields in the visual cortex?
- The left visual field is represented in the left occipital lobe and the right visual field is represented in the right occipital lobe
- The left visual field is represented in the right occipital lobe and the right visual field is represented in the left occipital lobe (correct)
- The visual field is not represented in the cerebral cortex
- The visual field is represented in the frontal lobe, not the occipital lobe
