Study Notes
Upper Limb
- Associated with the lateral aspect of the lower neck and the thoracic wall
- Suspended from the trunk by muscles and the sterno-clavicular joint (SCJ)
Bones of the Upper Limb
- Scapula: a flat triangular bone
- Clavicle
- Humerus: a long bone composed of head, neck, shaft, and condyles
- Radius
- Ulna
- Carpus: 8 carpal bones
- Metacarpals: 5 metacarpal bones
- Phalanges: 14 phalanges
The Scapula
- Articulates with the clavicle (ACJ)
- Articulates with the humerus (Gleno-humeral Joint)
- Articulates with the posterior wall of the thorax (Scapulo-Thoracic Joint)
The Humerus
- Upper end articulates with the scapula (Gleno-humeral Joint)
- Lower end articulates with the radius and ulna (elbow joint)
- Composed of head, neck, shaft, and condyles
Anatomical Features of the Humerus
Anterior View
- Greater Tubercle
- Lesser Tubercle
- Head of Humerus
- Anatomical Neck
- Intertubercular Sulcus
- Radial Groove
- Deltoid Tuberosity
Posterior View
- Humerus
- Medial Epicondyle
- Trochea
- Radial Fossa
- Coronoid Fossa
- Capitulum
The Hand
- Composed of carpal bones (8), metacarpals (5), and phalanges (14)
- Each finger has 3 phalanges: proximal, intermediate, and distal
- The thumb has only 2 phalanges: proximal and distal
Muscles of the Shoulder
- Connect bones of the upper limb to the trunk
Rotator Cuff Muscles
