  3. UPPER LIMB Efficiency of hand function ability to place it in the proper position by movements at the upperlimbjoints

  4. UPPER LIMB associated with lateral aspect of the lower portion of the neck thoracic wall Suspendedfrom the trunk by muscles &a small skeletal articulation between clavicle & sternum: sternoclavicular joint

  5. Shoulder proximal segment of the limb overlaps parts of the trunk (thorax and back) and lower lateral neck

  6. Pectoral (shoulder) gırdle • bony ring, • posteriorlyformed by the scapulae and clavicles • anteriorlybyformedby the manubrium of the sternum

  7. ARM -BRACHIUM Firstsegment of the free upper limb & longest segment of the limb Betweenshoulderandelbow Anterior & posteriorsegments of thearmaroundthehumerus

  8. Forearm-AntebrachIum Secondlongest segment of the limb Between elbow wrist & Includesanterior &posterior regions overlying the radius and ulna

  9. Hand-manus part of the upper limb distal to the forearm formed around the carpus, metacarpus, and phalanges. composed of the wrist, palm, dorsum of hand, and digits

  10. BONES OF THE PECTORAL GIRDLE CLAVICLE SCAPULA

  11. CLAVICLE Köprücük kemiği the only bony attachment between the trunk and the upper limb

  12. CLAVICLE Köprücük kemiği the only bony attachment between the trunk and the upper limb palpable along its entire length S-shaped contour forward-facing convex part medial forward-facing concave part lateral

  13. CLAVICLE medial sternal end articulates with manubrium sternoclavicular joint lateral end acromialend articulates with acromion of scapula acromioclavicularjoint

  14. CLAVICLE Inferiorsurface-neartheacromialend conoid tubercle–medialpart of- trapezoidline–lateralpart of- coracoclavicularligament Medial 1/3 of theclavicle’sshaft subclaviangroove – subclaviusmuscle Moremedially impression for the costoclavicularligament binding 1st ribtoclavicle Limitingelevation of theshoulder

  15. Functions of theClavicle Amoveable, rigid support limb has maximum freedom of motion. A boundaryof the cervico-axillary canal (passageway between the neck and the arm), protection to the neurovascular bundle supplying the upper limb. Transmits shocks from the upper limb to the axial skeleton.

  16. SCAPULA • Shoulderblade / Kürek kemiği large, flat triangular bone lies on the posterolateral aspect of the thorax between2nd-7th ribs

  17. SCAPULA • Anteriorview • three angles • lateral, superior, and inferior • three borders • superior, lateral, and medial • two surfaces • costal and posterior • three processes • Acromion • Spine • Coracoidprocess

  18. SCAPULA Posteriorview Acromion Supraspinous fossa Infraspinous fossa Spine of scapula Suprascapularnotch

  20. BONE OF THE ARM HUMERUS

  21. HUMERUS the largest bone in the upper limb articulates w/ Scapula Glenohumeral(Shoulder) joint Radius&Ulna elbow joint

  22. HUMERUS • In cross-section, shaft triangular with: • anterior, lateral, &medial • borders • anterolateral, anteromedial, posterior • surfaces • Intermuscular septa • attach to medial & lateral borders.

  23. HUMERUS proximalend Head Neck -Anatomicalneck -Surgicalneck Greatertubercle Lessertubercle Intertuberculargroove

  24. HUMERUS shaft Deltoid tuberosity Medial and lateral supraepicondylar(supracondylar) ridges Radial groove

  25. HUMERUS distalend Anteriorview • Posteriorview Radial fossa Coronoid fossa Olecranon fossa Capitilum Trochlea Medialepicondyle Lateralepicondyle

  26. BONES OF THE FOREARM • MORE IMAGES • 99-103 • RADIUS ULNA medial and longer of the two forearm bones • lateral and shorter of the two forearm bones

  27. articulation with humerusproximally head of the radius laterally ULNA proximalend • For articulation with the humerus • Olecranon • Coronoid process • Radialnotch • @ the lateral surface • articulation with head of radius Trochlear notchSemilunarnotch • Tuberosity of ulna • Inferior to coronoid process

  28. ULNA shaft Broad superiorly, continuous with large proximal end Narrow distally to form a small distal head • triangular in cross-section and has: • three borders anterior, posterior, and interosseous • three surfaces anterior, posterior, and medial • Supinatorcrest • Inferior to radial notch @ lateral surface • Supinator fossa • On thelateralsurface, undertheradialnotch Supinatormuscle

  29. ULNA distalend Ulnadoes not reachandparticipatetotheradiocarpal (wrist) joint! Head of theulna Ulnarstyloidprocess

  30. RADIUS • proximalend & shaft • A short head • Neck • Radial tuberosity • Obliqueline • The shaft of the radius • in contrast to that of the ulna • gradually enlarges • triangular in cross-section, with: • three borders • anterior, posterior, and interosseous • three surfaces • anterior, posterior, and lateral

  31. RADIUS • distalend • Dorsal tubercle of the radius • Radial styloid process • Ulnar notch • SHAFT • triangular in cross-section, with: • three borders • anterior, posterior, and interosseous • three surfaces • anterior, posterior, and lateral

  32. BONES OF THE HAND • MORE IMAGES • 104--108

BONES OF THE HAND • Distalrow of carpalbones • lateraltomedial • Trapezium • Trapezoid • Capitate • Hamate Table (Little)Head On a Hook Proximalrow of carpalbones lateraltomedial Scaphoid Lunate Triquetrum Pisiform I am sailingwithmylittleboat on a summernight Themoon is crescent I am fillingmythree-cornered hat withbeasfallingoffthesky

  36. BONES OF THE HAND Carpal arch The carpal bones do not lie in a flat plane; rather, they form an arch, whose base is directed anteriorly. lateral side of this base formed by tubercles of the scaphoid and trapezium. medial side formedby pisiform & hook of hamate. head base
