Study Notes
Eye Anatomy Key Terms
-
Optic Nerve: Vital for vision, this nerve transmits visual signals from the eye to the brain for processing.
-
Sclera: Known as the "white of the eye," it provides structural support and protection to the eyeball.
-
Cornea: Transparent layer that covers the front of the eye, playing a critical role in focusing light.
-
Lens: Flexible, transparent structure that focuses light rays onto the retina, adapting shape to allow for clear vision at varying distances.
-
Suspensory Ligaments: Connects the lens to the ciliary body, maintaining lens position and aiding in focusing by adjusting tension.
-
Pupil: The central opening of the eye that regulates the amount of light entering; its size changes in response to light intensity.
-
Iris: The muscular, colored part surrounding the pupil; it controls the size of the pupil to adjust light intake.
-
Vitreous Humor: Gel-like substance filling the eye's interior; it maintains the shape of the eyeball and helps keep the retina in place.
-
Blind Spot: The specific area where the optic nerve exits the eye; lacks receptor cells, resulting in an absence of visual perception at that point.
-
Retina: The light-sensitive layer at the back of the eye, containing rods and cones for detecting light and color, as well as neurons for processing visual inputs.
