If the axillary nerve primarily innervates the deltoid muscle and shoulder area, then why does an axillary nerve block affect the hand and lower arm? Wich nerve block would you use to deaden the deltoids and shoulder area?

because deltoid muscle actions are:-

-flexion & extention of the arm.

-medial & lateral rotation of the arm.

-upward rotation of the scapula. (from 15-90 degrees).

so it affect the most important actions of the arm.
