what is the autonomous zone of musculocutaneous nerve?

medial antebrachium

what is the autonomous zone of axillary nerve?

lateral shoulder

what is the autonomous zone of radial nerve?

lateral antebrachium

which nerves of the brachial plexus DO NOT have an autonomous zone?

median nerve
lateral thoracic nerve

what is the autonomous zone of femoral nerve?

medial side of the crus

what is the autonomous zone of the obturator nerve?

trick question: the obturator nerve does not have a cutaneous zone and therefore does NOT have an autonomous zone either
