Final answer:
The flexor retinaculum attaches to the trapezium, scaphoid, hamate, and pisiform bones in the wrist, forming the roof of the carpal tunnel. The carpal tunnel is a passageway for the tendons of nine muscles of the anterior forearm and an important nerve to enter the hand.
Step-by-step explanation:
The flexor retinaculum attaches to the trapezium, scaphoid, hamate, and pisiform bones in the wrist. It spans the top of the U-shaped grouping of the carpal bones to form the roof of the carpal tunnel. The carpal tunnel is a passageway for the tendons of nine muscles of the anterior forearm and an important nerve to enter the hand.
