Fibrous tunic of eyeball
Fibrous Tunic of Eyeball
The Fibrous Tunic of Eyeball (pronounced: /ˈfaɪbrəs ˈtjuːnɪk ɒv ˈaɪbɔːl/) is the outermost layer of the eye. It is composed of two parts: the sclera and the cornea.
Etymology
The term "Fibrous Tunic of Eyeball" is derived from the Latin words "fibra" meaning fiber, "tunica" meaning coat or layer, and "oculus" meaning eye.
Sclera
The sclera (pronounced: /ˈsklɪərə/) is the white part of the eye. It is a tough, fibrous tissue that covers about five-sixths of the eyeball and provides protection and form.
Cornea
The cornea (pronounced: /ˈkɔːrnɪə/) is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. The cornea, with the anterior chamber and lens, refracts light, with the cornea accounting for approximately two-thirds of the eye's total optical power.
Related Terms
- Iris (anatomy): The colored part of the eye that controls the diameter and size of the pupil and thus the amount of light reaching the retina.
- Pupil: The black circular opening in the iris that lets light in.
- Anterior chamber: The fluid-filled space inside the eye between the iris and the cornea's innermost surface, the endothelium.
- Lens (anatomy): A transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina.
