Which myotome pattern is associated with elbow extension?

The myotome pattern associated with elbow extension is linked to the C7 nerve root. This is significant because the triceps brachii muscle, which is primarily responsible for elbow extension, is innervated by the radial nerve, originating from the C7 nerve root. While other nerves and nerve roots contribute to the function of other muscles around the elbow, C7 is specifically key in this action.

Understanding myotomes is crucial in evaluating motor function and diagnosing potential nerve root injuries. Distinction among various myotomes helps healthcare professionals identify specific areas of compromised functionality based on muscle strength, providing insight into neurological conditions or injuries.
