Visual Pathway Quiz

What is the main topic of the video?

• The pathway vision

• Lesions in the visual pathway

• The occipital lobe

• The optic chiasm

Which structures are involved in the visual pathway?

• Occipital lobe, optic nerve, optic chiasm

• Lateral geniculate body, optic tract, occipital lobe

• Optic nerve, optic chiasm, lateral geniculate body, optic tract

• Optic nerve, occipital lobe, lateral geniculate body

What is the purpose of the blue nerve on the left side?

• To capture images from the left temporal field

• To carry visual information to the lateral geniculate body

• To synapse with neurons in the occipital lobe

• To pick up the left nasal field

What happens when a lesion occurs on the left optic nerve?

• Blindness in the left eye

• Loss of vision in the left nasal field

• Loss of vision in the right temporal field

• Blindness in the left nasal field

What is the result of a lesion occurring at the optic chiasm?

• Blindness in the temporal visual field

• Loss of vision in the left nasal field

• Loss of vision in the right temporal field

• Blindness in the central visual field

Which condition is characterized by loss of central vision?

• Right homonymous hemianopia

• Temporal Inman Opia

• Central schemata

• Macular degeneration

What happens when the macula is damaged?

• Loss of central vision

• Tunnel vision

• Loss of peripheral vision

• Constricted visual fields

What is the role of the midbrain in the visual pathway?

• To carry visual information to the occipital lobe

• To synapse with neurons in the lateral geniculate body

• To control reflexes related to the eyes

• To capture images from the nasal visual field

Which structure contains pigmented cells called cones?

• Optic chiasm

• Macula

• Occipital lobe

• Lateral geniculate body

What is the purpose of the blink and light reflex?

• To control central vision

• To carry visual information to the occipital lobe

• To protect the eyes from harm

• To synapse with neurons in the lateral geniculate body
