  1. 1- muscular branches supply muscles on the lateral side of the forearmRadial artery
  2. 2gives off the radial recurrent artery (supplies brachioradialis and brachialis m., and the elbow joint) which anastomoses with the radial collateral artery, a branch of the profunda brachiiRadial artery
  3. 3- at the wrist, covered only by superficial and deep fasciae and skin thus its pulsation can easily be feltRadial artery
  4. 4crosses the floor of the snuff box and ends by completing the deep palmar arterial arch in conjunction with the ulnar arteryRadial artery
  5. 5Branches Of Radial Arterya. muscular branches
    b. radial recurrent artery
    c. superficial palmar branch
    d. palmar carpal branch
    e. dorsal carpal branch
  6. 6arises at the distal end of the radius just proximal to the wrist - supplies muscles of the thenar eminence - anastomoses with the terminal part of the ulnar artery to form the superficial palmar arterial archsuperficial palmar branch (Radial Artery)
  7. 7arises near the distal border of the pronator quadratus - anastomoses with the carpal branch of the ulnar artery and recurrent branches of the deep palmar arch to form the palmar carpal archpalmar carpal branch (Radial Artery)
  8. 8- runs medially across the dorsal surface of the wrist, deep to the extensor tendons - anastomoses with the dorsal carpal branch of the ulnar artery to form the dorsal carpal archdorsal carpal branch (Radial Artery)
  9. 9- begins near the neck of the radius, just medial to the biceps tendonulnar artery
  10. 10- in the distal 2/3 of the forearm , the ulnar artery lies lateral to the ulnar nerveulnar artery
  11. 11leaves the forearm by passing superficial to the flexor retinaculum on the lateral side of the pisiform boneulnar artery
  12. 12- at the wrist, the ulnar artery and nerve lie lateral to the tendon of the flexor carpi ulnarisulnar artery
  13. 13- its pulse is not readily felt at the wrist because it is bridged by deep fascia ( the volar carpal ligament)ulnar artery
  14. 14branches supply medial muscles in the forearm and hand, the common flexor synovial sheath and the ulnar nerveulnar artery
  15. 15arises just inferior to the elbow and runs superiorly between the brachialis and pronator teres which it supplies - anastomoses with the inferior ulnar collateral a.anterior ulnar recurrent a
  16. 16- arises distal to the anterior ulnar recurrent a. - anastomoses with the superior ulnar collateral a. - takes part in the arterial anastomoses around theelbowposterior ulnar recurrent a.
  17. 17arises in the distal part of the cubital fossa and divides into anterior and posterior branchescommon interosseous a
  18. 18-passes distally on the interosseous membrane to the proximal border of the pronator quadratus - pierces the membrane at the level of the pronator quadratus and continues distally to join the dorsal carpal archanterior interosseous artery
  19. 19passes posteriorly b/n the bones of the forearm - supplies adjacent muscles - gives off the posterior interosseous recurrent a. which participates in the arterial anastomoses around the elbowposterior interosseous artery
  20. 20supply muscles on the medial side of the forearm, mainly the flexor-pronator groupmuscular branches
  21. 21anastomoses with the palmar carpal branch of the radial arterypalmar carpal branch
  22. 22arises just proximal to the pisiform bone - anastomoses with the dorsal carpal branch of the radial a.dorsal carpal branch
  23. 23continues into the palm as the superficial palmar archsuperficial palmar branch
  24. 24passes deeply in the hand - anastomoses with the radial artery and completes the deep palmar archdeep palmar branch
  25. 25NervesMedian – principal nerve of the anterior fascial compartment
    Ulnar
    Radial – enters the posterior compartment
  26. 26- Nerves of the anterior aspect of the forearm are only 2 in number:median and ulnar
  27. 27- enters the forearm with the brachial artery - has no branches in the armMedian Nerve
  28. 28Branches of Median Nervearticular branches
    muscular branches
    anterior interosseous nerve
    palmar cutaneous branch
  29. 29elbow jointarticular branches
  30. 30pronator teres, pronator quadratus, and all flexors except flexor carpi ulnaris and the medial half of the flexor digitorum profundus (ulnar nerve)muscular branches
  31. 31- passes inferiorly on the interosseous membrane with the anterior interosseous branch of the ulnar artery - supplies the flexor digitorum profundus, flexor pollicis longus and the pronator quadratus and ends by sending articular branches to the wrist jointanterior interosseous nerve
  32. 32supply the skin of the lateral part of the palmpalmar cutaneous branch
  33. 33covered by a slip of flexor retinaculumcanal of Guyon
  34. 34Ulnar Nerver branchesarticular branches
    muscular branches
    palmar cutaneous branch
    dorsal cutaneous branch
  35. 35arises from the ulnar nerve near the middle of the forearm and pierces the deep fascia in its distal third to supply skin on the medial part of palmpalmar cutaneous branch (Ulnar Nerve)
  36. 36- arises from ulnar nerve in distal half of forearm and passes inferiorly b/n the ulna and flexor carpi ulnaris - supplies posterior surface of medial part of handdorsal cutaneous branch (Ulnar Nerve)
  37. 37descends between brachialis and brachioradialis ---> crosses anterior aspect of lateral epicondyle of humerus ---> enters forearm ---> divides into superficial and deep branchesRadial Nerve
  38. 38- smaller of the 2 branches - direct continuation of the radial nerve - supplies skin on the dorsum of the wrist, hand, thumb and lateral 1 ½ digitssuperficial branch (Radial Nerve)
  39. 39larger of the 2 terminal branches - entirely muscular and articular in its distribution - supplies extensor carpi radialis brevis, supinatordeep branch (Radial Nerve)
  40. 40- pierces the supinator muscle and curving around the lateral side of the radius to enter the posterior fascial compartment of the forearmdeep branch (Radial Nerve)
  41. 41supplies extensor muscles - posterior interosseous n. – accompanies posterior interosseous artery and supplies deep extensorsdeep branch (Radial Nerve)
