Diagram Of The Eyelid

The eyelids act to protect the anterior surface of the globe from local injury.
Diagram of the eyelid. The lacrimal gland produces tears that help lubricate and moisten the eye as well as flush away any foreign matter that may enter the eye. The junctions where the upper and lower eyelids meet are known as the canthi singular canthus or commonly as the corner of the eyes or angle of the eyelids. The eyelids are thin mobile folds that cover the eyeball anteriorly they offer protection from excessive light or injury and maintain lubrication by distributing tears over the surface of the eyeball.
Additionally they aid in regulation of light reaching the eye. These areas are known as the medial palpebral commissure inner angle near the nose or lateral palpebral commissure outer angle. Infra orbital artery at the lower eyelid.
Diagram of the outer eye. An eyelid is a thin fold of skin that covers and protects the eye. When the eyes are closed this fissure appears to be nothing more than a line of connection.
Is primarily by the ophthalmic division of cn v v1. The pupil is the opening in the centre of the iris that regulates the amount of light entering the eye. In tear film maintenance by distributing the protective and optically important tear film over the cornea during blinking.
The small but detectable space between the upper and the lower eyelid is known as the palpebral fissure. The tears drain away from the eye through the nasolacrimal duct which is located at the inner. The eyelids are split into upper and lower portions which meet at the medial and lateral canthi of the eye the opening between the two eyelids is called the palpebral aperture or opening.
The colored part of your eye gets inflamed or infected. The main blood supply to the upper lid is the ophthalmic artery which gives off peripheral and marginal arcades. Hover the diagram to zoom.
