Crystalline Lens ✔✔Provides focusing power. the 2nd most powerful refractive medium
Medial Rectus ✔✔most powerful extraocular muscle. turns eye toward the nose (adduction)
Inferior Rectus ✔✔turns eye downward (depresssion). also adducts. can rotate top of eye toward
the temple and bottom of the eye towards the nose (extorsion)
Lateral Rectus ✔✔moves eye away from nose (abduction)
Superior Rectus ✔✔moves eye upwards (elevation). Also adducts. Rotates top of eye toward
nose and bottom of eye toward temple (intorsion)
Superior Oblique ✔✔Primary role is intorsion. Also depression and abduction
, Inferior Oblique ✔✔only extraocular muscle that's origin is at front of orbit. Primary role is
extorsion. Also elevation and abductino
Fovea Centralis ✔✔In macula (approx. 1.5 mm in diameter) where visual acuity is sharpest.
Contains highest number of cones which are responsible for daytime and color vision
Fundus ✔✔interior surface of eyeball
Iris ✔✔colored part of the eye. hole in the middle is pupil. Iris sphincter and dilator muscles
control size of pupil for max visual performance
Lens ✔✔resilient, transparent structure that focuses light by changes of curvature of front
surface. Directly behind the pupil.
Macula ✔✔central part of retina. used for seeing detail. Area is 3-5 mm in diameter. Foveal
depression is in center
Ocular Adnexa ✔✔adjacent structures including: eyelids, lashes, eyebrows, lacrimal apparatus,
tarsal plates, orbit, extraocular muscles, conjunctiva.
