EOMs (4

EOMs
Do rectus muscles insert symmetrically around the cornea? - ANS-No

The 4 rectus muscles insert___ - ANS-Anterior to the equator of the eye.

The lateral rectus and medial rectus are in the same _________ plane - ANS-The
lateral rectus and horizontal rectus are in the same horizontal plane.
The lateral rectus and medial rectus are antagonist muscles so when lateral rectus
contracts medial rectus relaxes.

The superior and inferior recti muscles are in the same ______ plane - ANS-vertical
plane

What are the branches of V-1 Opthalmic division of trigeminal nerve? - ANS-Frontal
nerve
Nasociliary nerve
Lacrimal nerve

What are the EOMS - ANS-4 rectus
superior oblique
inferior oblique

What EOMs make up the muscle cone?
Which EOM is outside of the muscle cone? - ANS-Lateral, medial, inferior, superior
rectus
Superior oblique is not in the muscle cone. It's up by the levator which isn't an EOM

What nerves pass through the cavernous sinus? - ANS-Optic nerve is above cavernous
sinus and won't be affected if something is wrong in the cavernous sinus.
ICA loops through cavernous sinus.
Within cavernous sinus:
Oculomotor III (innervates all EOMs except lateral rectus and superior oblique.
Parasymp div of III innerv ciliary muscle and constrictor pupillae of iris)
Abducens VI innerv lateral rectus
Trochlear IV innrev superior oblique
V-1 opthalmic div of trigeminal
V-2 Maxillary div of trigeminal
