Lesson 1Axillary nerve anatomy: root levels, course through quadrangular space, sensory territory over lateral shoulder (regimental badge)Covers axillary nerve root origins, path through the quadrangular space, and ties to the surgical neck and deltoid, linking to motor branches and sensory area on the lateral shoulder for pinpoint clinical localisation.
