Clavicle Type: long bone Site: anterior bone of shoulder girdle Ossification: membranous Joints (articulations) related to clavicle: 1) Sterno-clavicular joint: Type: synovial, saddle Movements; elevation, depression, protraction and retraction (secondary to movements of acromioclavicular joint) Sternoclavicular joint 2) Acromio-clavicular joint: Type: synovial, plane Movements; gliding Acromioclavicular joint Scapula Type: flat bone Site: posterior bone of shoulder girdle Anterior view Posterior view Acromion process Joints related to scapula: 1) Acromio-clavicular joint: Type: synovial, plane Movements; gliding Acromioclavicular joint 2) Shoulder joint: Type: synovial, multi-axial, ball and socket Movements; flexion, extension, adduction, abduction, medial rotation and lateral rotation Humerus Type: long bone Site: bone of the arm Joints (articulations) related to humerus: 1) Shoulder joint: Type: synovial, Multi-axial, ball and socket Movements; flexion, extension, adduction, abduction, medial rotation and lateral rotation 2) Elbow joint: Type: synovial, hinge Humerus Movements; flexion and extension, Radius Type: long bone Site: lateral bone of the forearm Joints (articulations) related to radius: 1) Elbow joint: Type: synovial, hinge Movements; flexion and extension 4) Wrist joint: Type: synovial, ellipsoid Movements; flexion, extension, adduction and abduction 2) Superior radio-ulnar joint: Type: synovial, pivot Movements; pronation &Supination 3) Inferior radio-ulnar joint: Type: synovial, pivot Movements; pronation & Supination Ulna *Type: Long bone Radius Ulna *Site: the medial bone of the forearm *Joints related: 1. Elbow joint: related to its upper end 2. Superior radio-ulnar joint 3. Inferior radio-ulnar joint Ulna Type: long bone Site: medial bone of the forearm Joints (articulations) related to radius: 1) Elbow joint: Type: synovial, hinge Movements; flexion and extension 2) Superior radio-ulnar joint: Type: synovial, pivot Movements; pronation&Supination 3) Inferior radio-ulnar joint: Type: synovial, pivot Movements; pronation&Supination Medial rotation of Lateral rotation of forearm is called forearm is called “pronation” “supination” Medial rotation of Lateral rotation of forearm is called forearm is called “pronation” “supination” Bones of the Hand Phalanges Metacarpal bones Carpal bones Dr Hossam Yahia Joints (articulations) related to carpal bones: 1) Wrist joint: Type: synovial, ellipsoid Movements; flexion, extension, abduction and adduction 2) Intercarpal joints: Type: synovial, plane Movements; gliding movements 3) Carpo-metacarpal joint of thumb: Type: synovial, saddle Movements; flexion, extension, adduction and abduction What is meant by a saddle joint? A joint in which each articular surface is concave in one direction and convex at the perpendicular one, e.g. carpo-metacarpal joint of thumb joint Interphalangeal Joints: Type: synovial, hinge Movements; flexion and extension Metacarpo-phalangeal Joints of medial 4 fingers: Type: synovial, condylar Movements; flexion, extension, adduction and abduction Carpo-metacarpal joint of thumb Pisiform: Site: most medial of the proximal row of carpal bones. Type: Sesamoid bone Joints related: intercarpal joint: Synovial, plane allowing gliding movement.
