Innervation of forearm and hand muscles

The video tutorial provides a comprehensive overview of the innervation of the forearm and hand, focusing on the median, ulnar, and radial nerves. It details the motor and sensory distributions of these nerves, their paths through the brachial plexus, and their topographical relationships to the humerus. The tutorial also covers the specific muscles and areas of the hand each nerve innervates, including the median nerve's role in the carpal tunnel, the ulnar nerve's passage through Guyon's canal, and the radial nerve's function in the posterior forearm.

What are the cutaneous distributions of the ulnar nerve?

How does the radial nerve innervate the forearm extensors?

What is the overall distribution of the median, ulnar, and radial nerves in the hand?
