Brachial Plexus and Upper Limb Nerves

Start with the plexus

Begin with a Brachial Plexus mind map that lays out roots, trunks, divisions and cords. It also names branches such as the long thoracic and musculocutaneous nerves. Use that structure to organize the terms before moving on to individual nerves.

The mind map titled The Brachial Plexus and Nerves of the Upper Limb connects the plexus to the muscles and skin of the arm. It also introduces myotomes. You can use it alongside the first map to see how the branches relate to the upper limb.

Connect nerves and muscles

Next, look at the Brachial Plexus mind map that focuses on the radial nerve. It includes its supply to the posterior arm and forearm, with muscles such as the triceps brachii and brachioradialis. Another map lists forearm muscles, including extensors.

For question-based study, the Brachial Plexus flashcards ask about lumbricals, their nerve supply and their movements. Upper Extremity Nerves lists nerves alongside muscles. The flashcards on the axilla, brachial plexus and breast also cover the boundaries of the axilla. These resources offer different ways to go over the structures in the maps.

Practice with a quiz

After studying the maps and cards, use The Brachial Plexus quiz to practice identifying spinal roots associated with upper limb dermatomes and myotomes. It includes image labeling and drag-and-drop questions, as well as a question about the axilla.

Return to a map when you want to trace a connection again, then use the quiz for another look at the questions. This topic is one section of Upper Limb in Anatomy, so its resources give you a focused way to study nerves within that unit. Choose a map and pair it with the quiz when you are ready.
