What nerve provides innervation to the upper limb?
The brachial plexus
The brachial plexus is a collection of nerve fibres that supply motor and sensory innervation to the upper limb. It originates from nerve roots C5 to T1 and, as it passes through the axilla, merges the nerve fibres from these roots into different nerve branches.
What nerve Innervates the top of the hand?
median nerve

What nerve Innervates the arm?

The radial nerve innervates the triceps brachii, lateral aspect of the brachialis, anconeus, brachioradialis, and extensor carpi radialis longus.
