14. Brachial art Neck of radius Ulnar art. Radial art. Tendon of biceps brachii m Lateral Medial Cubital fossa
15. Course of The Arteries of Forearm
16. Brachial artery Radial artery Ulnar artery & nerve Tendon of biceps Lateral Medial
17. Radial Artery It is the lateral artery in the forearm.
18. Course of Radial Artery
19. Brachial artery Tendon of biceps It leaves forearm by passing backwards below the lower end of radius to reach anatomical snuff box Lateral Medial It begins as a smaller terminal branch of brachial artery at level of neck of radius It passes downwards and laterally
20. Anatomical snuff box Radial artery
21. Anatomical snuff box
22. Surface Anatomy of Radial Artery in the Forearm
23. Point 1: 1 cm below line of elbow (flexion crease), medial to tendon of biceps brachii Point 2: Lower end of radius, lateral to tendon of flexor carpi radialis
24. Relations of Radial Artery ➢Superficial (anterior). ➢Deep (posterior). ➢Lateral. ➢Medial.
25. Superficial (anterior) Relations
26. Radial artery Brachioradialis m. (upper 2/3 of forearm) Lateral Medial Skin & Fascia (cubital fossa) Skin & fascia (lower 1/3 of forearm)
27. Deep (posterior) Relations
28. 1-Tendon of biceps m. 2-Supinator m. 3-Pronator teres m. 4-Radial head of flexor digitorum superficialis m. 5-Flexor pollicis longus m. 6-Pronator quadratus m. 7-Lower end of radius Lateral Medial
29. Medial Relations of Radial Artery
30. Pronator teres m. Radial artery Tendon of flexor carpi radialis m Lateral Medial
31. Lateral Relations of Radial Artery
32. Radial artery Brachioradialis m Lateral Medial
33. Radial artery Superficial radial nerve Brachio-radialis m.(cut) Medial Lateral
34. Ulnar Artery It is the medial artery of the forearm.
35. Course of Ulnar Artery
36. Brachial artery Ulnar artery & nerve Tendon of biceps Pisiform bone It begins as a larger terminal branch of brachial artery at level of neck of radius It leaves forearm by passing lateral to pisiform bone (superficial to flexor retinaculum) Lateral Medial It passes downwards and medially It passes downwards
37. Surface Anatomy of Ulnar Artery
38. Point 1: 1 cm below line of elbow (flexion line), medial to tendon of biceps Point 3: Just lateral to pisiform bone Point 2: Junction between upper 1/3 & lower 2/3 of a line between medial epicondyle and pisiform bone
39. Relations of ulnar artery ➢Superficial (anterior). ➢Deep (posterior). ➢Medial. ➢Lateral.
40. Superficial (Anterior) Relations
