Flexor Carpi Radialis: origin
Medial epicondyle of humerus
Flexor carpi radialis: insertion
Base of 2nd and 3rd metacarpals
Flexor carpi radialis: innervation
Median nerve
Flexor carpi radialis: action
Flexes and abducts wrist (radial deviation)
Palmaris longus: origin
Medial epicondyle of humerus
Palmaris longus: insertion
Flexor retinaculum and palmar aponeurosis
Palmaris Longus: innervation
Median nerve
Palmaris longus: action
Flexes wrist
Flexor digitorum superficialis: origin
Medial epicondyle of humerus, coronoid process of ulna
Flexor digitorum superficialis: insertion
Middle phalanges of digits 2-5
Flexor digitorum superficialis: innervation
Median nerve
Flexor digitorum superficialis: action
Flecos proximal interphalangeal joints and metacarpo-phalangeal joints of digits 2-5,and wrist
Flexor carpi ulnaris: origin
Medial epicondyle of humerus, olecranon, and posterior ulna
Flexor carpi ulnaris: insertion
Pisiform, hook of hamate, 5th metacarpal
Flexor carpi ulnaris: innervation

What are carpal tunnel?
House group of tendons and muscles
Not considered part of the carpal tunnel’s
Ulnar tunnel
Flexor retinaculum anterior and proximal row of carpals
Borders
Ligament that lies superficial to the ulnar artery and nerve…
Palmer ligament
Neurovasculature that goes into the ulnar tunnel distal to the Palmer ligament…
Ulnar neurovasculature
… divides into deep and superficial branches
Ulnar artery
… divides into deep and superficial branches
Ulnar artery
Structures located within the tunnel
- Median nerve
- Flexor digitorum superficialis tendons
- Flexor digitorum profundus tendons
Carpal tunnel syndrome
- wrist hyperextension decreases space within carpal tunnel
- friction between flexor digitorum tendon sheaths cause inflammation
- median nerve is compressed
- compartmental release
