Question | Answer |
Mucous membrane lining the inner surface of the eyelids and covering the surface of the eye | Conjunctivia |
Located in the lateral aspect of the roof of the orbit, superior and inferior parts | Lacrimal Gland |
Part of the eye where secretions from this gland pass through 6-12 ducts which open onto the conjunctiva | Lacrimal Gland |
Small openings into superior and inferior lacrimal canaliculi | Superior and Inferior Lacrimal Puncta |
Small tubular ducts leading to lacrimal sac | Superior and Inferior Lacrimal Canaliculi |
Enlarged cavity located in fossa for lacrimal sac | Lacrimal Sac |
Duct running from lacrimal sac and opening into nasal cavity | Nasolacrimal Duct |
Small reddish conical body of skin containing sebaceous and sweat glands | Lacrimal Caruncula |
Source of whitish secretion that collects in this area | Lacrimal Caruncula |
A semilunar fold of conjunctiva | Plica Semilunaris |
A triangular space at the medial angle of eye where tears collect | Lacrimal Lake |
Route of Tears | Lacrimal Gland, Lacrimal Lake, Lacrimal Puncta, Lacrimal Canaliculi, Lacrimal Sac, Nasolacrimal Duct, Nasal Cavity |
Outer layer of eyeball | Sclera |
Middle layer of eyeball | Choroid |
Inner layer of eyeball | Retina |
Contains axons leading from the retina to brain | Optic Nerve |
Retina contains what | rod and cone receptors |
Outer surface of the optic nerve is covered by what? | Dura |
Point of exit for fibers forming optic nerve | Optic Disk |
Lacks rod and cone receptors, thus insensitive to light (blind spot) | Optic Disk |
Yellow spot about half a millimeter in diameter consisting only of cone receptors | Macula Lutea |
Center of macula is a small pit | Fovea Centralis |
Point of critical vision (sharp focus) | Macula Lutea |
Situated between the iris and the vitreous body | Lens |
What acts to focus light on the retina? | Lens |
Act to suspend the lens via attachment to the ciliary body | Suspensory Ligaments |
Contains the ciliary muscle | Ciliary Body |
Watery fluid secreted by the ciliary body and contained within the anterior and posterior chambers of the eye | Aqueous Humor |
Transparent semigelatinous substance filling the vitreous chamber | Vitreous Body |
Colored part of the eye just anterior to the lens and surrounds the pupil | Iris |
2 parts of the Iris | constrictor/sphincter pupillae and dilator pupillae |
Inner circular layer of smooth muscle of the Iris | constrictor/sphincter pupillae |
Outer radiating layer of smooth muscle of the Iris | dilator pupillae |
What reduces pupil diameter (to bright light)? | constrictor/sphincter pupillae |
what increase pupil diameter (low light)? | dilator pupillae |
Opening for entrance of light into the eye | Pupil |
Clear, transparent extension of sclera over anterior 1/6 of eye | Cornea |
Between iris and lens | Posterior Chamber |
Between iris and cornea | Anterior Chamber |
Posterior to lens containing the vitreous body | Vitreous Chamber |
Minute small cavities at junction of iris and cornea - Drains aqueous humor from the anterior chamber | Trabeculae |
Drains aqueous humor from the trabeculae and delivers it to small veins in the immediate area | Scleral Venous Sinus (Canal of Schlemm) |
Route of Aqueous Humor | Ciliary body, posterior chamber, pupil, anterior chamber, trabeculae, scleral venous sinus, vein |
Raises upper eyelid | Levator Palpebrae Superioris |
Four Recti Muscles | Superior Rectus, Inferior Rectus, Medial Rectus and Lateral Rectus |
Elevates and Adducts Eye | Superior Rectus |
Depresses and Adducts Eye | Inferior Rectus |
Adducts Eye | Medial Rectus |
Abducts Eye | Lateral Rectus |
Two Oblique Muscles of the Eye | Superior Oblique and Inferior Oblique |
Action of the Superior Oblique Muscle | Depresses and Abducts |
Action of the Inferior Oblique Muscle | Elevates and Abducts |
