What is considered the main component of Carpal tunnel syndrome?

1. Compression of the median nerve

2. Inflammation of the wrist muscles

3. Weakness in the fingers

4. Numbness in the forearm

The correct answer is: Compression of the median nerve

The main component of Carpal Tunnel Syndrome is the compression of the median nerve. This condition occurs when the median nerve, which runs from the forearm into the palm of the hand, becomes squeezed or compressed as it travels through the carpal tunnel—a narrow passageway in the wrist. This compression can lead to various symptoms, including numbness, tingling, and weakness in the hand and fingers. Understanding the central role of median nerve compression helps highlight why interventions often focus on relieving pressure in the carpal tunnel, whether through ergonomic adjustments, splinting, or surgical options in more severe cases. Other symptoms, like inflammation of the wrist muscles or weakness in the fingers, are secondary effects that arise as a result of this compression.
