Study Notes
Eye Development and Structure
- The eye is derived from the ectoderm, mesoderm, and endoderm embryonic layers.
- The diameter of the eye in an adult is approximately 2.5 cm (1 inch).
- The skin layer (epidermis) does not contribute to the eye's embryology.
- The eyeball rests in the bony socket called the orbit.
- The eye is derived from the diencephalon part of the brain.
- The ectoderm layer also contributes to the development of the brain, including the diencephalon.
- The eye is roughly spherical in shape.
- Only about one-sixth of the eye's surface is exposed, with the rest being protected by the orbit and surrounding tissues.
