Arm (brachium)The part of the upper limb located between the shoulder and the elbow.
Elbow jointThe joint connecting the arm and the forearm, comprising the articulation between the humerus and the two forearm bones, ulna, and radius.
Brachial arteryThe major blood vessel of the upper arm that continues from the axillary artery to supply blood to the arm.
RadiusOne of the two bones of the forearm, extending from the lateral side of the elbow to the thumb side of the wrist.
UlnaThe longer and larger of the two bones of the forearm, placed on the side opposite to the thumb.
CorneaThe transparent front part of the eye that covers the iris, pupil, and anterior chamber.
IrisThe colored part of the eye, controlling the size of the pupil and thus the amount of light reaching the retina.
LensThe transparent structure inside the eye that focuses light rays onto the retina.
RetinaThe light-sensitive layer of tissue at the back of the inner eye, which translates light into neural signals for vision.
Fovea centralisA small central pit in the macula of the retina, composed of closely packed cones that is responsible for sharp central vision.
Optic nerveThe nerve that transmits visual information from the retina to the brain.
MaculaAn area near the center of the retina that is responsible for central vision and high visual acuity.
Vitreous humorThe clear gel that fills the space between the lens and the retina in the eyeball.
PhotoreceptorsCells in the retina that respond to light; they include rods, which are responsible for vision in low light, and cones, for color vision and detail.
ScleraThe white outer layer of the eyeball that provides protection and form.
ChoroidThe vascular layer of the eye between the retina and the sclera, supplying nutrients and oxygen to the eye.
Anterior chamberThe fluid-filled space inside the eye between the cornea and the iris.
Posterior chamberThe fluid-filled space directly behind the iris but in front of the lens.
ConjunctivaA clear mucous membrane that lines the inside of the eyelids and covers the sclera.
Lacrimal glandThe gland responsible for producing tears; it is situated in the upper outer region of the orbit, above the eyeball.
Aqueous humorThe clear, watery fluid that fills the space between the cornea and the iris.
MyopiaA common vision condition also known as nearsightedness, where distant objects appear blurred.
HyperopiaA vision condition also known as farsightedness, where close objects appear blurred.
AstigmatismA common imperfection in the curvature of the eye's cornea or lens, causing blurred or distorted vision.
Retinal detachmentA serious condition where the retina peels away from its underlying layer of support tissue.
Macular degenerationAn eye disease that may result in blurred or no vision in the center of the visual field due to damage to the macula.
GlaucomaA group of eye conditions that damage the optic nerve, often associated with increased pressure in the eye.
CataractsA condition characterized by clouding of the lens in the eye, leading to a decrease in vision.
ConjunctivitisAn eye condition diagnosed by irritation or infection of the conjunctiva, often resulting in redness and swelling.
KeratoconusA progressive eye disease where the normally round cornea thins and begins to bulge into a cone-like shape.
Bullous KeratopathyA condition causing swelling and blistering of the cornea due to endothelial cell dysfunction.
Corneal scarringOpacity or scarring of the cornea often resulting from injury, infection, or inflammation.
Extraocular musclesThe muscles that control the movements of the eye and the elevation of the eyelid.
Vitreous floatersSmall flecks or threads of collagen that float in the vitreous humor and cast shadows on the retina, often seen as floaters by the individual.
