Study Notes
Clavicle
- Long bone, but lacks a medullary cavity
- Acts as a rigid support for the scapula and upper limb
- Transmits force from the upper limb to the axial skeleton
- Provides attachment points for muscles
- Has two ends: medial (sternal) and lateral (acromial)
- Medial 2/3 of the shaft is convex forward, lateral 1/3 is concave forward
- Superior surface is smooth, inferior surface is rough due to ligament and muscle attachments
- Articulates with the sternum at the sternoclavicular joint (medial end)
- Articulates with the acromion of the scapula at the acromioclavicular joint (lateral end)
- Fractures are common, especially at the junction of the middle and lateral thirds
- Fractures can also occur during childbirth in infants with broad shoulders
Scapula
- Large, flat, triangular bone located between the 2nd - 7th ribs
- Provides attachment points for muscles
- Allows for free movement of the arm on the thoracic wall
- Has two surfaces: costal (concave anterior) and posterior
- Posterior surface is divided by the spine of the scapula
- Contains the supraspinous fossa (smaller, above the spine) and infraspinous fossa (larger, below the spine)
Ulna
- Part of the forearm
- Proximal end: includes the trochlear notch (articulates with the trochlea of the humerus) and the radial notch (articulates with the head of the radius)
- Shaft (body): cylindrical, broader superiorly and narrower inferiorly
- Distal end: small rounded head, connected to the shaft by the neck, medial styloid process
- Articulates with the trochlea of the humerus at the elbow joint (allows for flexion, extension, and some abduction/adduction)
- Articulates with the radius at the proximal and distal radio-ulna joints (allows for pronation and supination)
- Articulates with the carpal bones at the wrist joint
Radius
- Part of the forearm
- Head: articulates with the ulna at the proximal radio-ulna joint
- Shaft (body): cylindrical, slightly curved, has three surfaces
- Distal end: expands to articulate with the carpal bones at the wrist joint
- Articulates with the ulna at the proximal and distal radio-ulna joints (allows for pronation and supination)
Carpal Bones
- Eight bones forming the wrist divided into two rows of four
- Proximal row: scaphoid, lunate, triquetral, pisiform
- Distal row: trapezium, trapezoid, capitate, hamate
- Articulates with the radius at the wrist joint
- Articulates with the metacarpals distally
Metacarpals
- Five long bones in the palm of the hand
- Each metacarpal corresponds to a digit
Phalanges
- Fourteen bones forming the fingers
- Each finger (excluding the thumb) has three phalanges: proximal, middle, and distal
- The thumb has only two: proximal and distal
