polski), also known as the eyeball, is a vital component of the human eye. It is a spherical structure that houses the retina, lens, cornea, and other essential parts of the eye.
Etymology
The term "globe" comes from the Latin word "globus," meaning "sphere" or "ball." This term accurately describes the shape of the structure.
Anatomy
The globe is composed of three layers: the sclera, the uvea, and the retina. The outermost layer, the sclera, is a tough, white protective layer. The middle layer, the uvea, contains the iris, ciliary body, and choroid. The innermost layer, the retina, is responsible for processing light into signals that the brain can interpret.
The front of the globe is covered by the cornea, a clear layer that allows light to enter the eye. Behind the cornea is the aqueous humor, a fluid-filled chamber that helps maintain the shape of the globe. The lens is located behind the aqueous humor and focuses light onto the retina. The vitreous humor, a gel-like substance, fills the back of the globe and also helps maintain its shape.
