Iris (Anatomy) §

Group: 4 #group-4

Relations §

• Color Vision: The iris contains pigments that give it its color, which can affect color perception and vision.
• Eye Diseases: Various eye diseases and conditions can affect the iris, such as iritis (inflammation of the iris) and coloboma (a gap or defect in the iris).
• Ciliary Muscle: The ciliary muscle controls the shape of the lens and is connected to the iris.
• Vitreous Humor: The vitreous humor is a clear gel that fills the space between the lens and the retina, helping to maintain the shape of the eye.
• Eye Anatomy: The iris is a crucial part of the overall anatomy and structure of the eye, working in coordination with other components for proper vision.
• Cornea: The iris is located behind the cornea, which is the transparent front part of the eye.
• Eyelids: The eyelids protect the iris and other parts of the eye from injury and help distribute tears across the eye surface.
• Eye Muscles: The eye muscles control the movement of the eye and help position the iris and pupil for optimal vision.
• Lacrimal System: The lacrimal system produces tears that help lubricate and protect the eye, including the iris.
• Choroid: The choroid is a layer of blood vessels that nourish the iris and other parts of the eye.
• Retina: The iris controls the amount of light that reaches the retina, which is the light-sensitive layer at the back of the eye.
• Optic Nerve: The optic nerve transmits visual information from the retina to the brain.
• Depth Perception: The iris helps control the depth of field and focus of the eye, contributing to depth perception.
• Sclera: The sclera is the white outer protective layer of the eye, and the iris is visible through the opening in the sclera.
• Pupil: The iris surrounds the pupil, which is the opening that allows light to enter the eye.
• Visual Acuity: The iris plays a role in visual acuity by controlling the amount of light that enters the eye and reaches the retina.
• Lens: The iris controls the amount of light that reaches the lens by adjusting the size of the pupil.
• Aqueous Humor: The aqueous humor is a fluid that fills the space between the cornea and the iris, providing nourishment and maintaining eye pressure.
• Iris: The iris is the colored ring of the eye that surrounds the pupil.
• Conjunctiva: The conjunctiva is a thin membrane that covers the sclera and lines the inside of the eyelids, helping to protect the iris and other eye structures.
