Extra: Visual pathway neuron sequence: 1. **Bipolar cells** (1st order) 2. **Ganglion cells** (2nd order) — Axons form the optic nerve/tract. 3. **Lateral geniculate body** (3rd order) — Axons form the optic radiations. 4. **Primary visual cortex** (4th order) — Area 17 in the calcarine sulcus. Note: While some older texts count photoreceptors as the first-order, modern medical standards (Snell, Guyton) designate bipolar cells as the first-order neurons.
