Bones of Upper Limb ·Should girdle clavicle,scapula Bones of free upper limb -Humerus Radius and ulna Carpal bones,metacarpals and phalanges

Bones of Upper Limb • Should girdle clavicle，scapula • Bones of free upper limb – Humerus – Radius and ulna – Carpal bones, metacarpals and phalanges

Clavicle “S”shaped,medial23 convex forward and lateral 1/3 convex backward. Acromial end Sternal end Transmits shocks from upper limb to axial skeleton

Clavicle “S” shaped, medial 2/3 convex forward and lateral 1/3 convex backward. Sternal end Acromial end Transmits shocks from upper limb to axial skeleton

Scapula a triangular flat bone ·Three borders Superior:coracoid process, scapular notch Lateral (axillary)border Medial (vertebral)border ·Three angles Superior:opposite to the 2nd rib -Inferior:opposite to the 7th rib/intercostals space Lateral:glenoid cavity supra-and infraglenoid tubercles ·Two surfaces Anterior surface concave: subscapular fossa -Posterior surface: supra-and infraspinous fossae spine of scapula,acromion

Scapula • Three borders – Superior: coracoid process , scapular notch – Lateral (axillary) border – Medial (vertebral) border • Three angles – Superior: opposite to the 2nd rib – Inferior: opposite to the 7th rib / intercostals space – Lateral: glenoid cavity supra- and infraglenoid tubercles • Two surfaces – Anterior surface concave: subscapular fossa – Posterior surface: supra- and infraspinous fossae spine of scapula, acromion a triangular flat bone

Supraspinous fossa scapular notch coracoid process glenoid cavity acromion subscapular fossa spine of scapula Infraspinous fossa

Radius ·Upper end: head of radius neck of radius radial tuberosity radius. Shaft:interosseous border ·Lower end: radial styloid process ulnar notch carpal articular surface Radial Styloid

Radius • Upper end: head of radius neck of radius radial tuberosity • Shaft：interosseous border • Lower end: radial styloid process ulnar notch carpal articular surface Radial Styloid radius

olecranon Ulnar Radial notch -trochlear notch coronoid process ·Upper end: UInar tubersity olecranon coronoid process trochlear notch(large curved articular surface) radial notch ulnar ulnar tubersity ·Lower end styloid process of ulnar head of ulna

Ulnar • Upper end: olecranon coronoid process trochlear notch (large curved articular surface) radial notch ulnar tubersity • Lower end styloid process of ulnar head of ulna trochlear notch olecranon Ulnar tubersity coronoid process ulnar Radial notch
