Which nerves are responsible for the movement and sensitivity of the upper limb?

I - The musculocutaneous nerve originates in the brachial plexus and innervates the coracobrachial, biceps brachii, and anterior brachial muscles, as well as the external surface of the forearm.
II - The median nerve originates in the brachial plexus and innervates the pronator teres, flexor carpi radialis, palmaris longus, flexor digitorum superficialis, and flexor pollicis longus muscles, as well as the external surface of the palm and the first three and a half fingers.
III - The ulnar nerve originates in the brachial plexus and innervates the flexor carpi ulnaris, flexor digitorum profundus, and the intrinsic muscles of the hand, as well as the ulnar side of the palm and the fifth finger.
IV - The axillary or circumflex nerve originates in the brachial plexus and innervates the deltoid and teres minor muscles.
V - The radial nerve originates in the brachial plexus and innervates the triceps brachii, anconeus, brachioradialis, supinator, and extensor muscles of the forearm, as well as the posterior and external surface of the arm and the back of the hand.
