**Core Concept**
Carpel tunnel syndrome (CTS) is a neuropathic disorder caused by median nerve compression at the wrist level. The median nerve passes through the carpal tunnel, which is a narrow, fibrous passageway in the wrist. Compression of the median nerve within this tunnel can lead to symptoms such as numbness, tingling, and weakness in the hand.

**Why the Correct Answer is Right**
The most common cause of CTS is repetitive strain or overuse of the wrist and hand, leading to increased pressure on the median nerve. This can occur in occupations involving vibrating tools, heavy lifting, or prolonged typing. Other risk factors include fluid retention, diabetes, and certain medical conditions such as rheumatoid arthritis. The compression of the median nerve can also be caused by anatomical abnormalities, such as a narrow carpal tunnel or a ganglion cyst.
