Lesson 1Axillary nerve anatomy: root levels, course through quadrangular space, sensory territory over lateral shoulder (regimental badge)Mi detail di axillary nerve roots, how it run thru di quadrangular space, an how it link to di surgical neck an deltoid, den connect dat to it motor branches an sensory area pon di side a di shoulder fi easy clinical pinpointin.
