Nerve Whiz, developed by a neuromuscular neurologist at the University of Michigan, is a free educational tool tailored for medical professionals aiming to enhance their understanding of nerve roots, plexuses, and peripheral nerves. The app allows users to identify weak muscles and areas of sensory loss, providing detailed information with accompanying visuals such as pictures and diagrams.

With a comprehensive inventory of clinically relevant muscles in the upper and lower extremities, users can sort by various criteria like root, trunk, cord, peripheral nerve, action, or muscle name. Additionally, the Muscle Localizer feature offers possible localizations for weak muscles, while Nerve Diagrams provide detailed views of nerve anatomy within the context of the brachial or lumbosacral plexus.
