The conjunctiva "connecting garment" (lat. Tunica conjunctiva) is a mucous membrane of the anterior segment of the eye and surrounds the cornea and the visible white part of the eye. The conjunctiva distributes the tear fluid on the cornea with each blink.
Therefore, among other things, serves the mobility of the eye. The conjunctiva moistens itself through glands. If it becomes inflamed, this can lead to conjunctivitis. The conjunctiva forms a small fold towards the nose, which is also called the "third eyelid". In sharks, reptiles or birds, this is significantly larger than in humans and can be folded in front of the eye like transparent goggles.
Anatomy of the human eye
Optic nerve (lat. Nervus opticus) in the eye
The optic nerve is responsible for ensuring that information from the retina reaches the brain. The concentrated bundle of millions of nerve fibers converts the light stimuli from the retina into impulses and sends them to ...
Inner eye shell
The inner shell forms the retina. It is used to receive light stimuli. The light impressions are transmitted to the brain via the optic nerve and processed there.
Blind spot (papilla)
The so-called blind spot is the point in the eye where the retina is interrupted and merges with the optic nerve. Since there are no light receptors at this point, ...
