    • Insertion-The medial border of the radius b/w the proximal and middle thirds.
    • Action-Pronation; to flex the elbow.
    • Innervation- Median nerve.
  2. Flexor carpi radialis
    • Origin- The medial epicondyle (humerus); the medial border of the radius.
    • Insertion- The palmer side of the base of metacarpals I and II.
    • Action- To flex the carpus.
    • Innervation- Median nerve.
  3. Superficial digital flexor
    • Origin- The medial epicondyle (humerus).
    • Insertion- The palmar surface of the proximal end of the middle phalanges of digits II-V.
    • Action- To flex the carpal, metacarpophalangeal, and proximal joints of digits II-V.
    • Innervation- Median nerve.
  4. Flexor carpi ulnaris
    • Origin- Ulnar head (the caudal border and medial surface of the olecranon); the medial epicondyle (humerus).
    • Insertion- The accessory carpal bone.
    • Action- To flex the carpus.
    • Innervation- Ulnar nerve.
  5. Deep digital flexor
    • Origin- The medial epicondyle (humerus); the ulnar head (proximal 3/4 of caudal border); the radial head (middle third of the medial border).
    • Insertion- The flexor tubercle on the palmer surface of the distal phalanx of each digit.
    • Action- To flex the carpal and metacarpophalangeal joint and the proximal and distal interphalangeal joints.
    • Innervation- Median and ulnar nerves.
  6. Pronator quadratus
    • Attachments- The apposed surfaces of the radius and ulna.
    • Action- To pronate the paw.
