Which deep tendon reflex is linked to the C7 nerve root?

The triceps reflex is linked to the C7 nerve root. This reflex is tested by striking the triceps tendon, typically located just above the elbow, with a reflex hammer. When the C7 nerve root is intact and functioning properly, this action triggers a contraction of the triceps muscle, resulting in elbow extension.

Understanding the specific nerve roots associated with deep tendon reflexes is essential for assessing neurological function. The C7 nerve root specifically contributes to the motor control of muscles, such as the triceps. Therefore, when evaluating a patient's reflex response, the triceps reflex serves as an indicator of the integrity of the C7 nerve root and, more broadly, the corresponding neural pathway.
