The _____ nerve travels with the posterior circumflex humeral artery around the surgical neck of the humerus

Branches of the medial cord of the brachial plexus (Mnemonic: M4U): - _____ (C8, T1) - Medial cutaneous nerve of the arm (C8, T1) - Medial cutaneous nerve of the forearm (C8, T1) - Ulnar nerve (C8, T1) - Medial root of the median nerve (C8, T1)

Muscles of the thenar eminence:1. _____2. Abductor pollicis brevis3. Flexor pollicis brevis

Upper lateral cutaneous nerve of the arm is a branch of the _____ nerve
