Carpal Tunnel Contents and Structures That Pass Through
These flashcards cover the structures that pass through the carpal tunnel — a clinically critical anatomy topic for medical students, PT students, and anyone preparing for boards or anatomy lab practicals. Understanding what travels through the carpal tunnel (and what doesn't) is essential for diagnosing carpal tunnel syndrome, interpreting nerve compression symptoms, and mastering wrist anatomy. These cards reinforce the boundaries, contents, and clinical implications you'll need to recall quickly on practical exams.

How many tendons pass through the carpal tunnel?
9 tendons pass through the carpal tunnel: 4 from flexor digitorum superficialis, 4 from flexor digitorum profundus, and 1 from flexor pollicis longus. Together with the median nerve, that makes 10 total structures.
What is the difference between the carpal tunnel and Guyon's canal?
Carpal tunnel transmits the median nerve and 9 flexor tendons; compression causes thenar wasting and lateral 3½ finger numbness.
Guyon's canal (ulnar canal) transmits the ulnar nerve and artery; compression causes hypothenar wasting and medial 1½ finger numbness.
- Key distinction: the ulnar nerve does not pass through the carpal tunnel
How do I remember what passes through the carpal tunnel?
Use the mnemonic 1 nerve + 9 tendons: the median nerve plus 4 FDS + 4 FDP + 1 FPL tendons = 10 structures total. Remember that the ulnar nerve and palmaris longus both travel outside the tunnel.
