Which tendon is involved in the biceps tendon reflex?

The biceps tendon reflex is specifically elicited by tapping over the biceps tendon, which is located in the anterior compartment of the upper arm. This reflex assesses the integrity of the C5 and C6 segments of the spinal cord, particularly testing the function of the biceps brachii muscle. When the biceps tendon is stimulated, it causes a contraction of the biceps muscle, resulting in flexion at the elbow.

This reflex is a classic neurological test used by clinicians to evaluate the function of the nervous system. The involvement of the biceps tendon in this reflex is essential as it highlights its role in both the muscular and neurological response during the testing process. It is important to note that other tendons such as those from the rotator cuff, triceps tendon, and flexor tendons serve different purposes and are involved in different reflexes or movements, making them unrelated to the biceps tendon reflex.
