¨ Cavernous sinus contents

O TOM CAT
O TOM are lateral wall components, in order from superior to inferior. CA are the components within the sinus, from medial to lateral. CA ends at the level of T from O TOM. · See diagram.  Occulomotor nerve (III) Trochlear nerve (IV) Ophthalmic nerve (V1) Maxillary nerve (V2) Carotid artery Abducent nerve (VI) T: When written, connects to the T of OTOM.

Muscles
¨ Face muscles groups cranial innervation

Mandibular nerve: Mastication.
Facial nerve: Facial expression.
¨ Pterygoid muscles

Function of lateral vs. medial
"Look at how your jaw ends up when saying first syllable of 'Lateral' or 'Medial' ":
"La": your jaw is now open, so Lateral pterygoid opens mouth.
"Me": your jaw is still closed, so Medial pterygoid closes the mandible.
¨ Eye rotation by oblique muscles
