Joints of the Clavicle
- 1-Acromioclavicular joint: A plane synovial joint located between the acromial end of the clavicle and the medial margin of the acromion.
- 2-Sternoclavicular joint: A modified saddle synovial joint situated between the clavicular notch of the manubrium sterni and the first costal cartilage, and the sternal (medial) end of the clavicle.
Joints of the Scapula
- 1-Acromioclavicular joint: A plane synovial joint.
- 2-Shoulder joint: A polyaxial ball and socket synovial joint located between the head of the humerus and the glenoid cavity of the scapula.
Joints of the Humerus
- 1-Shoulder joint: A polyaxial ball and socket synovial joint.
- 2-Elbow joint: A hinge synovial joint. The trochlea articulates with the trochlear notch of the ulna, and the capitulum articulates with the superior surface of the head of the radius.
Joints of the Radius
- 1-Elbow joint: A hinge synovial joint.
- 2-Superior radioulnar joint: A uniaxial pivot synovial joint between the circumference of the head of the radius and the radial notch of the ulna.
- 3-Inferior radioulnar joint: A uniaxial pivot synovial joint. The head of the ulna articulates with the ulnar notch of the radius.
- 4-Wrist joint: A biaxial ellipsoid synovial joint. Located between the inferior surface of the lower end of the radius and the carpal bones (scaphoid and lunate).
Joints of the Ulna
- 1-Elbow joint: A uniaxial hinge synovial joint.
- 2-Superior radioulnar joint: A uniaxial pivot synovial joint between the circumference of the head of the radius and the radial notch of the ulna.
- 3-Inferior radioulnar joint: A uniaxial pivot synovial joint. The head of the ulna articulates with the ulnar notch of the radius.
Joints of the Hand
- 1-Carpometacarpal joint of the thumb: A biaxial saddle joint.
- 2-Metacarpophalangeal joint: A biaxial ellipsoid joint.
- 3-Interphalangeal joint: A uniaxial hinge joint.
