ANATOMY EYE Flashcards
Lacrimal gland anatomy
1) secretes tears = parasympathetic fibres from facial nerve
=> above the eye
2) lacrimal ducts = excretory ducts of lacrimal gland
3) Lacrimal sacs = receives tears
Eye chambers and boundaries , what do they contain?
1) Anterior chamber = Cornea –> Iris , it contains Aq humour
2) Posterior chamber = iris –> Lense , it contains Aq humour
3) Large chamber behind the Lens = vitreous chamber
layers of the eye ?
1) Cornea
2) Uvea ( iris, ciliary body and choroid)
3) retina
bones around the eye
from the lacrimal papilla ( inner corner)
clockwise
(6)
1) ethmoid bone = above
2) lacrimal bone
3) maxilla
4) Sphenoid bone
5) Zygomatic bone
6) Frontal Bone
what are the muscles which surround the eye
north , south , east ,west
TOP= Superior Rectus Muscle
BOTTOM= Inferior Rectus Muscle, inferior oblique muscle
Inner (medial )= Medial Rectus muscle
Outer= Lateral Rectus Muscle
What muscle connects the eye ball to the trochlea
->Superior Oblique Tendon and muscle
what nerves control eye movement
Assuming the right side is damaged
3rd => Oculomotor = right eye is down and out , unable to adduct ( towards ur nose)
4th=>Trochlea = Right up and out = elevates more when it adducts
6th => Abducens = right eye turns medially
