What is the function of the sclerotic layer?

The sclera forms the posterior five-sixths of the connective tissue coat of the globe. It is continuous with the dura mater and the cornea, and maintains the shape of the globe, offering resistance to internal and external forces, and provides an attachment for the extraocular muscle insertions.

What is the function of sclerotic in human eyes?

Sclera: This is commonly referred to as the white of the eye. It is fibrous and provides support for the eyeball, helping it keep its shape. Conjunctiva: A thin, transparent membrane that covers most of the white of the eye, and the inside of the eyelids. It helps lubricate the eye and protect it from microbes.

What is the function of the fibrous layer?

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.

What are the functions of each part of the eye?

The sclera, or white part of the eye, protects the eyeball. The pupil, or black dot at the centre of the eye, is an opening through which light can enter the eye. The iris, or coloured part of the eye, surrounds the pupil. It controls how much light enters the eye by changing the size of the pupil.

What does the ciliary body do?

The ciliary body is found behind the iris and includes the ring-shaped muscle that changes the shape of the lens when the eye focuses. It also makes the clear fluid that fills the space between the cornea and the iris.

What does the ciliary muscle do?

The ciliary body produces the fluid in the eye called aqueous humor. It also contains the ciliary muscle, which changes the shape of the lens when your eyes focus on a near object. This process is called accommodation.

What is choroidal?

The choroid (pronounced “CORE-oyd”) is a spongy layer of blood vessels that lines the back wall of the eye between the retina and the sclera (or the white part of the eye). It plays an important role in delivering oxygen and nutrients to the outer half of the retina.

What is the function of each layer of the retina?

The cellular layers of the retina are as follows: 1) The pigmented epithelium, which is adjacent to the choroid, absorbs light to reduce back reflection of light onto the retina, 2) the photoreceptor layer contains photosensitive outer segments of rods and cones, 3) the outer nuclear layer contains cell bodies of the ...

Where is vitreous humor produced?

Produced by cells in the non-pigmented portion of the ciliary body, the vitreous humour is derived from embryonic mesenchyme cells, which degenerate after birth. The nature and composition of the vitreous humour changes over the course of life.

What is the function of the anterior chamber of the eye?

Anterior chamber: The anterior chamber is the front part of the eye between the cornea and the iris. The iris controls the amount of light that enters the eye by opening and closing the pupil. The iris uses muscles to change the size of the pupil.

What are the two 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).

What is the outer corner of the eye called?

Canthus (pl. canthi, palpebral commissures) is either corner of the eye where the upper and lower eyelids meet. More specifically, the inner and outer canthi are, respectively, the medial and lateral ends/angles of the palpebral fissure.
