Which deep tendon reflex is related to C6?

The brachioradialis reflex is indeed associated with the C6 nerve root. This reflex tests the integrity of the radial nerve and the associated portion of the central nervous system. When the brachioradialis tendon is tapped with a reflex hammer, a normal response is the flexion of the elbow, which indicates proper functioning of the C6 spinal segment.

This reflex is often tested in clinical settings to evaluate neurological function, particularly related to upper limb movements. Testing the reflex can help in diagnosing conditions affecting the C6 nerve root, which may stem from issues such as cervical radiculopathy or nerve entrapment syndromes.

Other reflexes mentioned in the question, such as the triceps reflex, are associated with different nerve roots, specifically C7, while the adductor and extensor digitorum reflexes pertain to other segments and muscles of the body. Understanding the connections between specific reflexes and their corresponding spinal levels is crucial in clinical assessments of nerve function.
