This course focuses on individual parts of the eye, starting from the outside and exploring inward. After exploring the cornea, it examines the extraocular muscles, the conjunctiva, the uveal tract, the crystalline lens, and the retina. Finally, it describes how the central nervous system works together with the eyes to enable vision. This course follows "Human Eye 1," and will enable the student to further describe the basic anatomy and many specific conditions of the human eye.
Prerequisite: completion of Human Eye 1.

Course Description
Sight begins when light enters the cornea, the clear window of the eye. This course focuses on individual parts of the eye, starting from the outside and exploring inward. After exploring the cornea, it examines the extraocular muscles, the conjunctiva, the uveal tract, the crystalline lens, and the retina. Finally, it describes how the central nervous system works together with the eyes to enable vision. For each part of the eye, the course examines related conditions. This course follows "Human Eye 1," and it will enable the student to further describe the basic anatomy and many specific conditions of the human eye.
