Nervous System—The Eyes
Lecture no. 11 from the course: Understanding the Human Body: An Introduction to Anatomy and Physiology, 2nd Edition
Taught by Professor Anthony A. Goodman | 44 min | Categories: The Great Courses Plus Online Science Course
This lecture examines the eyes. We examine the anatomy of the eyeball, its coverings and functions, and the photoreceptors of the retina that allow us to perceive shades and colors of light. We also review the structure and functions of the lens, eyelids, lacrimal glands and ducts, and extrinsic eye muscles. Next, we consider how the eye perceives light and how the brain converts those perceptions into meaningful information.
