Carpal tunnel syndrome anatomical structure involved?

Carpal tunnel syndrome involves the median nerve, which runs through the carpal tunnel—a narrow passageway in the wrist formed by the carpal bones and the transverse carpal ligament. When the tunnel becomes compressed due to swelling or other factors, it can lead to symptoms such as pain, numbness, and tingling in the hand and fingers. This condition is often associated with repetitive wrist movements or conditions that cause inflammation. Treatment may include splinting, corticosteroid injections, or surgery to relieve pressure on the median nerve.
