Clavicle
the anterior bone of a pectoral girdle that articulates with the manubrium of the sternum
Sternoclavicular joint
the articulation point of clavicle and sternum
Scapula
a large, triangular, flat bone located in the superior part of the posterior thorax between the levels of the 2nd and 7th rids
Acromioclavicular joint
the articulation point between clavicle and scapula
Glenohumeral (shoulder) joint
the articulation point between the scapula and humerus
Sternal end
The medial end of clavicle that articulates with the manubrium of the sternum
Acromial end
the lateral end of the clavicle that articulates with the acromion of the scapula
Conoid tubercle
A projection on the inferior lateral surface of the clavicle. It is an attachment point for the conoid ligament, which attaches scapula and clavicle
Impression of the costoclavicular ligament
On the inferior surface and medial end of the clavicle. It is an attachment point for the costoclavicular ligament, which attaches the clavicle and first rib.
Spine
A prominent ridge that runs diagonally across the posterior of scapula
Acromion
located at the lateral end of the spine of scapula, it is an expanded and flattened process
Inferior angle
the angle where the medial (vertebral) border and the lateral (axillary) border of scapula meet, it is at the inferior end of the scapula
Superior angle
the angle where the medial border and the superior border meet.
Superior border
the superior edge of the scapula
Scapular notch
a prominent indentation along the superior edge of scapula through which the suprascapular nerve pass
Infraspinous fossa
depression on the posterior scapula surface, inferior to the spine, on to which infraspinatus muscles of shoulder attach
Supraspinous fossa
depression on the posterior surface of scapula, superior to the spine, on to which supraspinatus muscle of shoulder attach
Subscapular fossa
a hollowed out area on the anterior surface of the scapula, it is where the subscapularis muscle of shoulder attach
Coracoid process
located at the lateral end of the superior border, it is an anterior projection, on to which tendon and ligaments attach
Medial (vertebral) border
the thin medial edge of scapula that is close to the vertebrae
Lateral (axillary) border
the thick lateral edge of the scapula that is close to the humerus
Humerus
The longest and largest bone of the upper limb
Head of humerus
the proximal end of humerus that articulates with the glenoid cavity to form the glenohumeral joint
Anatomical neck
distal to the head of humerus, it is the former site of the adult epiphyseal growth plate
Greater tubercle
distal to the anatomical neck, it is a lateral projection
Lesser tubercle
distal to the anatomical neck of humerus, it projects anteriorly
Intertubercular sulcus (groove)
the groove/depression between the greater and lesser tubercle
Surgical neck
just distal to the greater and lesser tubercles, it is where the head tapers off to the shaft of the humerus, it is named so because it is often where fracture occurs
Body (shaft)
part of the humerus where it is cylindrical at its proximal end, but gradually becomes more triangular until it is flat and broad at its distal end
Deltoid tuberosity
in the middle lateral portion of the shaft, it is a V-shaped roughened projection
Radial groove
on the posterior surface of the body (shaft), it runs along the deltoid tuberosity and contains the radial nerve
Capitulum
it is a rounded knob on the lateral aspect of the bone that articulates with the head of the radium
Radial fossa
it is an anterior depression just above the capitulum that articulates with the head of radium when the forearm is flexed
Trochlea
Just medial to the capitulum, it is a spool-shaped surface that articulates with the trochlear notch of the ulna
Coronoid fossa
just above the trochlea, it is an anterior depression that receives the coronoid process of ulna when forearm is flexed
olecranon fossa
it is a posterior depression that receives the olecranon of the ulna when the forearm is extended
lateral and medial epicondyles
these are rough projections on the lateral and medial side of the distal end of humerus. Most of the tendons of the forearm muscles attach on to these
