Study Notes
Eye Structure and Functions
- The fibrous tunic is the outer layer of the eye that protects it and maintains its shape.
- The vascular tunic, also known as the uvea, is the middle layer of the eye that provides blood and controls the light entering the eye.
- The neural tunic is the inner layer of the eye that is primarily responsible for converting light into electrical signals.
- The three layers that make up the wall of the eye are the fibrous tunic, vascular tunic, and neural tunic.
Eye Components and Functions
- The lacrimal glands produce the watery part of tears.
- The meibomian glands produce the oily part of tears, preventing them from evaporating too quickly.
- The ciliary muscles, located in the ciliary body, control the shape of the lens.
- The ciliary body connects the iris to the choroid and contains the ciliary muscles.
- The iris primarily controls the entry of light into the eye.
Tear Production and Distribution
- The lacrimal glands and meibomian glands work together to produce tears.
- The meibomian glands' oily secretion prevents tears from evaporating too quickly.
- The eyelids, specifically the eyelid margins, are responsible for spreading tears across the surface of the eye as you blink, lubricating and protecting it from foreign materials.
Additional Functions
- The vascular tunic is responsible for providing blood to the eye and controlling the light entering the eye.
- The neural tunic is responsible for converting light into electrical signals.
