Basilic Vein
|
1) Passes up the medial ulnar side
2) Penetrates the deep (brachial) fascia at approximately mid-arm (the medial antebrachial cutaneous nerve passes superficially through the same opening of the brachial fascia) c. into the axilla as the Axillary vein (Note: the vena Comitantes of the brachial artery do not become the axillary vein) |
|
|
Cephalic vein
|
1) radial side of arm
2) communicates with basilic vein in front of the elbow, via median cubital vein (venipuncture) 3) superiorly along deltopectoral groove enters deltopectoral triangle pierces clavipectoral fascia to join axillary vein |

Clavicle
|
- 1st long bone to ossify, last one to finish
a. Palpable throughout its length b. Sternal (medial) end - articulates with the sternum at the sternoclavicular joint c. Acromial (lateral) end articulates with the acromion of the scapula at the acromioclavicular joint d. Medial 2/3 - convex anteriorly e. Lateral 1/3 - concave anteriorly f. Functions: 1. Acts as a strut holding the upper limb free from the trunk maximizing the freedom of action. This allows the SCAPULA to move on to the thoracic wall, at the conceptual “scapulothoracic joint, thereby increasing the range of motion of the upper limb 2. Transmits forces from the upper limb to the axial skeleton 3. Muscle attachment |

|
Scapula
|
- Lies on the posterolateral thorax covering ribs 2-7
- Connects the clavicle to the humerus - Surface anatomy 1. Root of the spine - spinous process of T3 2. Superior angle - T2 3. Inferior angle - T7 (good guide to the 7th intercostal space) |
