Function of vitreous chamber

Overview What are aqueous humor and vitreous humor? One definition of the word “humor” is “a bodily fluid,” and this is true for the fluids found in your eye — the aqueous humor and the vitreous humor. Your The vitreous humor, also called vitreous fluid, is a clear gel-like substance that’s located in your eye. It takes up the space between your eye’s lens and retina. The vitreous cavity is the name of this space. The vitreous humor helps your eye keep its shape. Function What is the purpose of aqueous humor and vitreous humor? The aqueous humor flows in and out of the front of your eye. Its job is to keep proper ocular pressure (eye pressure) in your eye. The pressure is maintained by having the same amount of fluid come in as the amount of fluid leaving the front of your eye. This fluid fills the anterior and posterior chambers of your eye. The vitreous humor provides nutrients to your eye and helps your eye keep its shape. It sticks to your retina at the back of your eye and lets light in. Your retina is the part of your eye that communicates with your brain so you can see. Forensic scientists sometimes use the vitreous humor to find substances in a deceased body that aren’t expected to be there naturally. Anatomy Where are the aqueous humor and vitreous humor located? Both the aqueous humor and the vitreous humor are parts of your eye. Location of the aqueous humor Your eye has an anterior chamber, which is the area between your lens and In the posterior chamber, the c...

Knowledge of the histology of the eye is important for understanding disease pathophysiology and treatment, as many diseases of the eye are manifestations of pathology within specific histological layers. This article describes the histological classification of the tissues of the eye and its external structures. Contents • 1 Accessory Structures • 1.1 Eyelid • 1.2 Lacrimal Apparatus • 1.3 Conjunctiva • 2 Chambers of the Eye • 3 Internal Structures of the Eye • 3.1 Sclera • 3.2 Cornea • 3.3 Iris • 3.4 Ciliary Body • 3.5 Lens • 3.6 Choroid • 3.7 Retina • 3.8 Optic disc • 3.9 Macula and Fovea • 4 Additional Resources • 5 References Accessory Structures Eyelid From superficial to deep, the eyelid is made of epidermis, dermis, the orbicularis oculi muscle, the orbital septum, the tarsal plate, and the palpebral conjunctiva. • The epidermis is composed of layers of keratinocytes with melanocytes, Langerhans cells, and Merkel cells. The underlying basal layer is composed of a single row of columnar-shaped cells containing melanin from adjacent melanocytes. • The dermis is a composed of delicate collagen fibrils, containing the vasculature, lymphatics, eyelashes, and nerve fibers. It also contains the following glands: • Glands of Zeis are sebaceous glands of the eyelashes, concentrated at the lid margin • Glands of Moll are modified apocrine sweat glands that open onto eyelash follicles. • Eccrine sweat glands are distributed throughout the eyelid skin. • Sebaceous glands are lo...

Eyeball (Bulbus oculi) The eye is a highly specialized sensory organ located within the The average human eye can see around 100 different shades of color and has a resolution that equals 576 gigapixels. These remarkable features of our eye are enabled by the complex structure of the eyeball. The eyeball consists of three layers; fibrous, vascular and nervous ( This article will discuss the Key facts about the eyeball Definition and function Spheroidal sensory organ that receives the visual stimuli and conveys them to the brain Parts Fibrous layer (sclera, cornea) Vascular layer (choroid, ciliary body, iris) Nervous layer (retina) [Overview of the eyeball] [Anterior eyeball] The eyeball consists of three distinct layers. From • The fibrous layer, which consists of the sclera is an opaque layer which surrounds the posterior five-sixths of the eyeball. The cornea is a transparent layer that is anteriorly continuous with the sclera, occupying the anterior one-sixth of the eyeball. • The vascular layer, also known as the uvea or uveal tract. It consists of three parts that are continuous with each other. From posterior to anterior, they are the • The nervous layer, also known as the retina, which is the innermost layer of the eyeball. The retina itself is divided into two layers; an outer, pigmented layer, and an inner neurosensory layer. These three layers comprise the circular outline of the eyeball. The inside of the eye contains the two refractive structures of the eye c...

Anterior chamber. The front section of the eye's interior where aqueous humor flows in and out, providing nourishment to the eye. Aqueous humor. The clear watery fluid in the front of the eyeball. Blood vessels. Tubes (arteries and veins) that carry blood to and from the eye. Caruncle. A small, red portion of the corner of the eye that contains modified sebaceous and sweat glands. Choroid. The thin, blood-rich membrane that lies between the retina and the sclera and is responsible for supplying blood to the outer portion of the retina. Ciliary body. The part of the eye that produces aqueous humor. Cornea. The clear, dome-shaped surface that covers the front of the eye. Iris. The colored part of the eye. The iris is partly responsible for regulating the amount of light permitted to enter the eye. Lens (also called crystalline lens). The transparent structure inside the eye that focuses light rays onto the retina. Lower eyelid. Skin that covers the lower part of the eyeball, including the cornea, when closed. Macula. The central portion of the retina that allows us to see fine details. Optic nerve. A bundle of nerve fibers that connect the retina with the brain. The optic nerve carries signals of light, dark, and colors to a part of the brain called the visual cortex, which assembles the signals into images and produces vision. Posterior chamber. The back part of the eye's interior. Pupil. The opening in the middle of the iris through which light passes to the back of the ey...
