Exam 1 - Upper Limb Intro Flashcards
Identify the parts of the Scapula (with a picture or bone)
Acromion, Infraspinous fossa, Neck of Scapula, Supraspinous fossa, Spine, Subscapular fossa, Body, Coracoid process
Study the surface anatomy landmarks of the upper arm.
Jugular notch, Sternoclavicular articulation, Acromion process, Acromioclavicular joint, scapular spine, greater tubercle of humerus, Lateral epicondyle of humerus, medial epicondyle of humerus, head of radius, Styloid process of ulna, Styloid process of radius, Olecranon process of ulna.
Match Arteries/Veins to Tributaries/Branches
Arteries have branches and Veins have tributaries.
Follow the main arteries of the upper limb.
Subclavian to the Axillary to the Brachial then to the Radial and Ulnar
What is the path of the main upper limb veins from distal to proximal.
Dorsal arch or Palmar arch lead to Cephalic vein which leads to Basilic vein leading to the Axillary vein and then the Subclavian vein.
