Adnexa
surrounding structures of the eye, (orbit, muscles, eyelid, and lacrimal system)
6 Extra Ocular Muscles
Medial Rectus, Lateral Rectus, Superior Oblique, Inferior Oblique, Superior Rectus, Inferior
Rectus
Medial Rectus
turns eye in towards nose = adduction
Lateral Rectus
turns eye out towards temple = abduction
Superior Oblique
twists eye down and in = incyclotorsion
Inferior Oblique
twists eye up and out = excyclotorsion
Superior Rectus
turns eye up = secondarily incyclotorsion or elevation
Inferior Rectus
turns eye down = secondarily excyclotorsion or depression
,Axial length
distance from front to back of the eye (23-25mm)
Cilia
Eyelashes
Medial canthus
inner corner of the eye

, Aqueous Humor
fluid that fills the Anterior Chamber
Pathway through which fluid leaves the eye
Anterior chamber angle to the trabecular meshwork to the canal of Schlemm to the aqueous
veins
Uvea or Uveal tract
iris, ciliary body, and choroid
