Extrinsic muscles of tongue [for pro soccer fans]
“Paris St. Germain’s Hour”:
PSG is a French soccer team (foreign), hence extrinsic comes to mind.
Eye rotation by oblique muscles
“I Love S&M“:
Inferior oblique: Lateral eye rotation.
Superior oblique: Medial eye rotation.
Extraocular muscles: movements
“ObliqLiques cause lateral rotation of eyeball”:
Obliques cause lateral, all other rectii are medial rotators of the eyeball.
Action of the obliques is opposite to their names.
Action of the rectii is rightly fitting to their names.
Both superiors cause intorsion and both inferiors cause extorsion.
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 opens mouth.
“Me“: your jaw is still closed, so medial closes the mandible.
Face muscles: large muscle groups’ cranial innervation
- Mandibular nerve: Mastication.
- Facial nerve: Facial expression.
Cricoarytenoids: abductor vs. adductor
When aliens abduct you, they Probe you.
Posterior cricoarytenoids abduct. Lateral therefore is adduct by default.
