Special Senses | Eye Anatomy

Official Ninja Nerd Website: https://ninjanerd.org/ Ninja Nerds! In this lecture, Professor Zach Murphy will present on the anatomy of the human eye, focusing on how its structures work together to create vision. We begin by exploring how light enters the eye through the cornea and aqueous humor, passes through the pupil, and is focused by the lens onto the retina. The roles of accommodation, controlled by the ciliary muscles and zonular fibers, and the regulation of light entry by the iris and pupil are discussed in detail. We then move into the phototransduction process, explaining how photoreceptor cells (rods and cones) convert light into electrical signals. The lecture highlights the differences in function between rods (low-light and peripheral vision) and cones (color and high-acuity vision) and the importance of the fovea for sharp central vision. Neural pathways from the retina through the optic nerve, optic chiasm, and optic tracts to the visual cortex are described, showing how visual information is processed in the brain. The discussion also covers the physiology of visual adaptation, comparing how the eye adjusts to bright and dim environments, and the role of the retinal pigment epithelium in photoreceptor health. We conclude by connecting these physiological processes to comprehensively understand how the eye captures and interprets the visual world.
