an emergency procedure where a cut or passageway is made in the cricothyroid membrane.
what lies posterior to the transverse cervical artery and suprascapular artery as they cross the anterior surface of the scalenus anterior muscle.
the sternal head of the sternocleidomastoid attaches to what?
muscle that opens the pharyngeal orifice of the eustachian tube during swallowing
