Joints of the appendicular skeleton:
● Sternoclavicular
○ Articular components
■ Between sternal end of clavicle, manubrium of sternum, and first costal
cartilage
○ Classification
■ Structural
● Synovial (plane and pivot)
■ Functional
● Freely movable
○ Movements
■ Gliding, with limited movement in nearly every direction
● Acromioclavicular
○ Articular components
■ Between acromion of scapula and acromial end of clavicle
○ Classifications
■ Structural
● Synovial (plane)
■ Functional
● Freely movable
○ Movements
■ Gliding and rotation of scapula on clavicle
● Radioulnar
○ Articular components
■ Proximal radioulnar joint between head of radius and radial notch of ulna
■ Distal radioulnar joint between ulnar notch of radius and head of ulna
○ Classifications
■ Structural
● Synovial (pivot)
■ Functional
● Freely movable
○ Movements
■ Rotation of forearm
● Wrist (radiocarpal)
○ Articular components
■ Between distal end of radius and scaphoid, lunate, and triquetrum of
carpus
○ Classifications
■ Structural
● Synovial (condyloid)
■ Functional
● Freely movable
Document Summary
Between sternal end of clavicle, manubrium of sternum, and first costal cartilage. Gliding, with limited movement in nearly every direction. Between acromion of scapula and acromial end of clavicle. Gliding and rotation of scapula on clavicle. Proximal radioulnar joint between head of radius and radial notch of ulna. Distal radioulnar joint between ulnar notch of radius and head of ulna. Between distal end of radius and scaphoid, lunate, and triquetrum of. Flexion, extension, abduction, adduction, circumduction, and slight. Between proximal row of carpal bones, distal row of carpal bones, and between both of carpal bones (midcarpal joint) Synovial (plane), except for hamate, scaphoid, and lunate (midcarpal) joint, which is synovial (saddle) Gliding plus flexion, extension, abduction, adduction, and slight rotation at midcarpal joint. Carpometacarpal joint of thumb between trapezium of carpus and first metacarpal. Carpometacarpal joints of remaining digits formed between carpus and second through fifth metacarpals. Synovial (saddle) at thumb and synovial (plane) at remaining digits hyperextension of wrist.
