Which deep tendon reflex is associated with the L2 nerve root?

The adductor reflex is associated with the L2 nerve root. This reflex can be elicited by tapping the inner thigh, which stimulates the adductor muscles, particularly the adductor longus and adductor brevis. The sensory information from this area travels via the L2 nerve root to the spinal cord, where it synapses and generates a motor response to contract the adductor muscles.

The other reflexes mentioned are linked with different nerve roots. The brachioradialis reflex involves the C5-C6 nerve roots, the triceps reflex corresponds to the C6-C7 nerve roots, and the extensor digitorum reflex is associated with the C7-C8 nerve roots. Understanding the relationships between specific reflexes and their corresponding nerve roots is crucial for evaluating neurological function and identifying potential lesions in the nervous system.
