Outer coat (fibrous tunic) The eye’s outer layer is made of dense connective tissue, which protects the eyeball and maintains its shape. It is also known as the fibrous tunic. The fibrous tunic is composed of the sclera and the cornea. The sclera covers nearly the entire surface of the eyeball.
What is the outer layer of the eye wall?
sclera
The outer layer of the eyeball is a tough, white, opaque membrane called the sclera (the white of the eye). The slight bulge in the sclera at the front of the eye is a clear, thin, dome-shaped tissue called the cornea.
What is the outer layer of the eye made of?
Most of the outer layer is composed of a tough white fibrous tissue, the sclera. At the front of the eye, however, this opaque outer layer is transformed into the cornea, a specialized transparent tissue that permits light rays to enter the eye.
What are the layers of the wall of the eye?
The eye is made up of three layers: the outer layer called the fibrous tunic, which consists of the sclera and the cornea; the middle layer responsible for nourishment, called the vascular tunic, which consists of the iris, the choroid, and the ciliary body; and the inner layer of photoreceptors and neurons called the …
Which anatomical structures are parts of the outer layer of the eye quizlet?
Which anatomical structures are parts of the outer layer of the eye? The sclera is the tough, white, exterior layer of the eye. The cornea is a transparent bulge that refracts and allows light rays to pass through, and is found in the outer layer.
What is the outermost layer of the retina?
The center of the macula is called the fovea. The inner surface of the retina is adjacent to the vitreous of the eye. The outermost layer of the retina, the retinal pigment epithelium, is tightly attached to the choroid.
Which anatomical structures are parts of the outer layer of the eye?
The outer layer contains the sclera (the white of the eye) and the cornea (the clear dome at the front of the eye). The cornea is like a window into the eye. It lies in front of the iris, the coloured part of the eye.

What are the outer retinal layers?
The outer retinal layers of the normal eye show three distinct bands on the spectral domain OCT: (1) retinal pigment epithelium (RPE) band – con- sisting of the RPE, Bruch’s membrane and cho- riocapillaris; (2) anterior to the RPE – comprising external limiting membrane, inner segment-out- er segment (IS-OS) line, and …
What is the outer retina?
The inner retina consists of the internal limiting membrane through to the external limiting membrane, and the outer retina consists of the photoreceptor layers through to the choroid.

What are the five special senses? What are the two parts of the outer layer of the eye? What is included in the middle layer of the eye? Choroid, the ciliary muscle and the iris.
What are the external structures of the eye?
The parts of the eye that are visible externally comprise of the external structure of the eye-. Sclera: It is a tough and thick white sheath that protects the inner parts of the eye. We know it as the ‘White of the eye’. Conjunctiva: It is a thin transparent membrane that is spread across the sclera.
What are the three main layers of your eye?
Three layers. The structure of the mammalian eye can be divided into three main layers or tunics whose names reflect their basic functions: the fibrous tunic, the vascular tunic, and the nervous tunic. The fibrous tunic, also known as the tunica fibrosa oculi, is the outer layer of the eyeball consisting of the cornea and sclera.
What are the layers of the eye?
Anatomically, the eyeball can be divided into three parts – the fibrous, vascular and inner layers. In this article, we shall consider the anatomy of the eyeball in detail, and its clinical correlations. The eyeball can be divided into the fibrous, vascular and inner layers.
What is the normal anatomy of the eye?
The inside lining of the eye is covered by special light-sensing cells that are collectively called the retina. It converts light into electrical impulses. Behind the eye, your optic nerve carries these impulses to the brain. The macula is a small extra-sensitive area in the retina that gives you central vision.
