Dr. Morton explains the brachial plexus, focusing on myotomes and peripheral nerves. The tutorial covers the motor deficits from injuries to spinal roots versus peripheral nerves, detailing the C5 to T1 spinal levels and their associated actions. Practice questions help reinforce understanding of nerve injuries and their effects on motor function. The video concludes with tracing sensory and motor neurons, emphasizing the importance of understanding myotomes and peripheral nerves.
