The Structure of the Eye Quiz: Test Your AP Psychology Knowledge

📚 Quick Study Guide

• 👁️ Anatomy: The eye includes structures like the cornea, iris, pupil, lens, retina, fovea, and optic nerve.
• 💡 Cornea: The transparent outer layer that helps focus light.
• 🌈 Iris: The colored part of the eye that controls pupil size.
• ⚫ Pupil: The opening in the iris that allows light to enter.
• 👓 Lens: Focuses light onto the retina through accommodation.
• 📸 Retina: Contains photoreceptor cells (rods and cones).
• ☀️ Rods: Detect black and white; important for night vision.
• 🎨 Cones: Detect color; concentrated in the fovea.
• 📍 Fovea: The central focal point in the retina; contains only cones.
• 🧠 Optic Nerve: Transmits visual information from the retina to the brain.
• 🔄 Visual Processing: Light enters the eye, is focused by the cornea and lens, and stimulates photoreceptors in the retina. Neural signals are then sent to the brain for processing.
