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
