Study Notes
Clavicle
- A long bone located at the anterior aspect of the shoulder girdle.
- Ossification occurs through membranous processes.
- Sternoclavicular joint: synovial, saddle type; allows elevation, depression, protraction, and retraction.
- Acromioclavicular joint: synovial, plane type; permits gliding movements.
Scapula
- A flat bone situated at the posterior side of the shoulder girdle.
- Acromioclavicular joint: synovial, plane type; allows gliding movements.
- Shoulder joint: synovial, multi-axial, ball and socket type; enables flexion, extension, adduction, abduction, medial rotation, and lateral rotation.
Humerus
- A long bone forming the upper arm.
- Shoulder joint: synovial, multi-axial, ball and socket; allows flexion, extension, adduction, abduction, medial rotation, and lateral rotation.
- Elbow joint: synovial, hinge type; facilitates flexion and extension.
Radius
- A long bone located on the lateral side of the forearm.
- Elbow joint: synovial, hinge type; allows flexion and extension.
- Wrist joint: synovial, ellipsoid type; facilitates flexion, extension, adduction, and abduction.
- Superior radio-ulnar joint: synovial, pivot type; enables pronation and supination.
- Inferior radio-ulnar joint: synovial, pivot type; also allows pronation and supination.
Ulna
- A long bone positioned medially in the forearm.
- Elbow joint: synovial, hinge type; involved in flexion and extension.
- Superior radio-ulnar joint: synovial, pivot type; supports pronation and supination.
- Inferior radio-ulnar joint: synovial, pivot type; facilitates pronation and supination.
Movements of Forearm
- Medial rotation is called "pronation."
- Lateral rotation is referred to as "supination."
Bones of the Hand
- Comprised of phalanges, metacarpal bones, and carpal bones.
- Wrist joint: synovial, ellipsoid type; allows flexion, extension, abduction, and adduction.
- Intercarpal joints: synovial, plane type; permit gliding movements.
- Carpo-metacarpal joint of the thumb: synovial, saddle type; allows flexion, extension, adduction, and abduction.
- Interphalangeal joints: synovial, hinge type; enable flexion and extension.
- Metacarpo-phalangeal joints of the medial four fingers: synovial, condylar type; permit flexion, extension, adduction, and abduction.
Pisiform Bone
- The most medial carpal bone in the proximal row.
