Nerve anatomy

Radial nerve innervation and radial nerve distribution. What are causes & treatment of radial nerve palsy, radial nerve entrapment & radial nerve injury.

This issue has come up in Question 21.1 from the first paper of 2014. The candidates were invited to label a diagram of a dermatome-mapped homunculus. In order to supply the candidates with a readily available visual reference for this question, I have reproduced two free Wikipedia images in this revision article.

Radial nerve is a terminal branch of the posterior cord and supplies the majority of the muscles in the posterior compartment of the arm/forearm/hand. Arises from posterior cord of the brachial plexus (C5-8, T1) Spirals posterolaterally around the humerus with the deep brachial artery in the spiral groove. Gives off posterior cutaneous nerve of forearm, which passes posterior to lateral condyle and supplies posterior forearm It pierces the lateral intermsucular septum into the anterior…

A neuron is a nerve cell that processes and transmits information through electrical and chemical signals in the nervous system. Neurons consist of a cell body, dendrites (which receive signals), and an axon (which sends signals). Synaptic connections allow communication between neurons, facilitating the relay of information throughout the body.
