Optic nerve

This tutorial by Megan from Ken Hub covers the optic nerve and visual pathway. It explains the structures involved, such as the ocular bulb, retina, optic chiasm, and lateral geniculate nucleus. The tutorial also discusses the superior colliculus and its role in eye movement. Clinical notes on optic neuritis and vision loss are provided, highlighting conditions like multiple sclerosis and optic nerve lesions.

Describe the pathway of visual information from the retina to the visual cortex.

Explain the difference between the temporal retina and the nasal retina.

What is the primary function of the optic nerve?

What happens to the visual information at the optic chiasm?

Describe the role of the lateral geniculate nucleus in the visual pathway.

What is the significance of the primary visual cortex in processing visual information?

How do the superior colliculi contribute to visual processing?

What is optic neuritis and what are its common symptoms?

How does damage to the optic nerve before the optic chiasm affect vision?

What is bitemporal hemianopsia and what can cause it?
