Carotid sheath contents: I See 10 CC's in the IV
I See (I.C.) = Internal Carotid artery 10 = CN 10 (Vagus nerve) CC = Common Carotid artery
IV = Internal Jugular Vein
External carotid artery branches Some Anatomists like freaking out poor medical students
Superior thyroid Ascending pharyngeal L ingual F acial O ccipital P osterior auricular M axillary
Superificial temporal
Foramen ovale contents: OVALE
Otic ganglion (just inferior) V3 cranial nerve Accessory meningeal artery Lesser petrosal nerve Emissary veins
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.
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

Composition of cranial nerves (Motor, Sensory, or Both): Some Say Marry Money, But MyBrother Says Big Brains Matter MoreSensory, sensory motor, motor, both, motor, both, sensory, both, both, motor, motor in the order of cranial nerves starting from the optic (cranial nerve I).
Lacrimal nerve path: Lacrimal's story of 6 L'sL acrimal nerve runs above L ateral rectus, then L ets zygomaticotemporal branch join in, thensupplies L acrimal gland, then Leaves it and supplies skin of upper eye L id! Trigeminal nerve relations in the skull (foramina): Standing R oom O nly
Superior orbital fissure is V1 (1st branch) foramen Rotundum is V2 foramen Ovale is V3

Thyroid: isthmus location Rings 2,3,4 make the isthmus floor
Isthmus overlies tracheal rings 2,3,4
Voicebox: names of parts in sagittal cross-section There's 3 V 's in your Voicebox
Vestibular fold Ventricle Vocal fold
Note: Vestibular and Vocal cord also known as false and true cords respectively.
Pterygoid muscles (function): Look at how your jaw ends up when saying first syllable of 'Lateral' or 'Medial'
"La": your jaw is now open, so Lateral opens mouth. "Me": your jaw is still closed, so medial closes the mandible.
Extrinsic muscles of tongue: People should generate history
P alatoglossus Styloglossus G enioglossus H yoglossus
Cricoarytenoids: abductor vs. adductor When aliens abduct you, they P robe you
Posterior cricoarytenoids abduct . Lateral therefore is adduct by default.
