Which bone is commonly known as the collarbone?
Clavicle
Scapula
Humerus
Sternum
The clavicle, or collarbone, connects the upper limb to the axial skeleton at the sternum. It acts as a strut to hold the shoulder laterally. Its subcutaneous position makes it palpable along its course. Learn more.
Which bone is also known as the shoulder blade?
Scapula
Clavicle
Ulna
Radius
The scapula is commonly called the shoulder blade and lies on the posterior thoracic wall. It articulates with the humerus at the glenoid cavity to form the shoulder joint. It also serves as an attachment site for several muscles. Learn more.
What is the name of the bony projection on the lateral end of the scapular spine?
Acromion
Coracoid process
Glenoid cavity

Sternoclavicular joint
Acromioclavicular joint
Glenohumeral joint
Scapulothoracic joint
The sternoclavicular joint is the articulation between the medial clavicle and the manubrium of the sternum. It is a saddle?type synovial joint allowing elevation, depression, and rotation. It is the only bony articulation between the upper limb and axial skeleton. Learn more.
What movement occurs when you lift your shoulders upward toward your ears?

Quadrangular space
Triangular space
Triangular interval
Deltopectoral triangle
The quadrangular space is bounded by teres minor, teres major, long head of triceps, and humerus. It transmits the axillary nerve and posterior circumflex humeral artery. Injury here can cause deltoid paralysis. Learn more.
Which nerve runs through the triangular interval along with the profunda brachii artery?

Which ligament bridges the radial notch of the ulna and holds the radial head in place?
Annular ligament
Quadrate ligament
Interosseous ligament
Oblique cord
The annular ligament encircles the head of the radius and secures it within the radial notch of the ulna. The quadrate ligament also provides support but is less significant. Annular ligament tears lead to radial head subluxation. Learn more.

Serratus anterior
Rhomboid major
Trapezius
Levator scapulae
Serratus anterior originates on the ribs and inserts along the medial border of the scapula. It protracts and rotates the scapula upward. Damage to its long thoracic nerve causes 'winged scapula.' Learn more.

Which embryological process forms the upper limb bones?
Endochondral ossification
Intramembranous ossification
Perichondral ossification
Heterotopic ossification
Long bones of the upper limb develop through endochondral ossification. A cartilage model is first formed and later replaced by bone. Intramembranous ossification forms flat bones like parts of the skull. Learn more.
Which anatomical space transmits the suprascapular nerve?
Suprascapular foramen
Quadrangular space
Triangular interval

Cheat Sheet
Scapular Landmarks & Mnemonic -
Mastering the bones of pectoral girdle and upper limb starts with the scapula's key landmarks - spine, acromion, coracoid process, and glenoid cavity, as outlined in Gray's Anatomy. Use the mnemonic "SCAG" (Spine, Coracoid, Acromion, Glenoid) to recall their order moving laterally. Mapping these on a diagram helps reinforce your pectoral girdle labeling skills in lab practice.
Clavicle Curvature & Fracture Zones -
The clavicle's S-shape has a medial convex and lateral concave curve, making its middle third most prone to fractures (University of Oxford Anatomy Lab Manual). Visualize the angles by sketching the sternal and acromial ends and noting the slender midshaft as the "bottle-neck." This insight proves crucial when studying pectoral girdle and upper limb injuries in trauma modules.
Humeral Anatomy & Radial Nerve Pathway -
Identify the humerus's proximal head, greater and lesser tubercles, surgical neck, and deltoid tuberosity before tracing the radial groove on the posterior shaft (Harvard Med School resource). Since the radial nerve courses here, midshaft fractures (Holstein-Lewis fractures) can lead to wrist drop. Labeling these regions strengthens retention for both pectoral girdle quiz questions and clinical correlations.
Pectoral Girdle Articulations -
Review the three major joints - sternoclavicular (saddle), acromioclavicular (plane), and glenohumeral (ball-and-socket) - each outlined in the American Academy of Orthopaedic Surgeons' guides. Think of the rotator cuff muscles - supraspinatus, infraspinatus, teres minor, subscapularis (SITS) - as stabilizers around the glenoid. This joint-muscle interplay is a staple in any pectoral girdle and upper limb labeled diagram.
Scapulohumeral Rhythm & Movement Ratio -
Scapulohumeral rhythm describes the 2:1 motion ratio between glenohumeral and scapulothoracic joints during arm elevation, as demonstrated in the Journal of Anatomy (2017). Remember the "120-60 Rule" to predict how the scapula and humerus work in concert during abduction. Applying this in pectoral girdle labeling exercises helps visualize functional anatomy dynamically.
