Study OutcomesCheat Sheet
Colorful paper art promoting Scapula Anatomy Showdown quiz for anatomy students.

Which of the following is the primary function of the scapula?
Support the lower limbs
Protect the abdominal organs
Provide a stable base for arm movements
Facilitate breathing by rib movement
The scapula forms the foundation for upper limb movements through multiple muscle attachments, making it essential for shoulder stability. The other options do not relate to scapular structure or function.
Which landmark on the scapula forms the highest point and is often palpable on the shoulder?
Coracoid process
Acromion
Glenoid cavity
Spine of scapula
The acromion is the most prominent bony projection on the scapula and is easily palpable on the shoulder. The other structures are either less accessible or serve different functions.
What is the primary articulating surface for the humerus located on the scapula called?
Coracoid process
Glenoid cavity
Scapular spine
Acromion
The glenoid cavity (or glenoid fossa) is the concave surface that articulates with the head of the humerus, forming the shoulder joint. The other options play different roles in scapular anatomy.
Which part of the scapula provides attachment for the clavicle?
Glenoid cavity
Scapular body
Acromion
Inferior angle
The acromion forms the acromioclavicular joint by articulating with the clavicle, making it the attachment site for the clavicle. The other parts do not have this function.
Which muscle is primarily responsible for keeping the scapula stable against the thoracic wall?
Rectus abdominis
Biceps brachii
Serratus anterior
Triceps brachii
The serratus anterior anchors the scapula to the thoracic wall and plays a crucial role in maintaining scapular stability. The other muscles listed are not primarily involved in scapular stabilization.
Which bony projection on the scapula serves as an attachment point for the short head of the biceps and several ligaments?
Acromion
Coracoid process
Glenoid cavity
Inferior angle
The coracoid process is a key projection that provides attachment for muscles like the short head of the biceps and for various ligaments. The alternative choices serve other structural and functional roles in the scapula.
What is the role of the scapular spine in scapular anatomy?
It divides the scapula into the supraspinous and infraspinous fossae
It articulates with the clavicle
It provides attachment for the rhomboids
It forms the lateral border
The scapular spine separates the scapula into the supraspinous and infraspinous fossae, facilitating distinct muscle attachments. The other options do not accurately describe its anatomical function.
Which component of the scapula is critical in forming the scapulothoracic articulation?
Glenoid cavity
Scapular body
Coracoid process
Acromion
The large, flat surface of the scapular body interacts with the thoracic wall to form the scapulothoracic articulation. The other parts are primarily involved in forming joints with the clavicle or humerus.
Which muscle works in conjunction with the scapula to facilitate upward rotation crucial for overhead arm movement?
Deltoid
Latissimus dorsi
Serratus anterior
Pectoralis major
The serratus anterior, in coordination with the trapezius, is essential for upward rotation of the scapula, enabling the arm to move overhead. The other muscles do not primarily contribute to this specific movement.
Which feature of the scapula is most commonly assessed in cases of scapular winging?
Coracoid process
Medial border
Glenoid cavity
Acromion
A pronounced or abnormal medial border is a characteristic sign observed in scapular winging, indicating improper scapular stabilization. The other features are not typically associated with this condition.
Which ligament attaches the scapula to the clavicle, playing a crucial role in the acromioclavicular joint's stability?
Coracoclavicular ligament
Glenohumeral ligament
Transverse ligament
Coracoacromial ligament
The coracoclavicular ligament connects the coracoid process of the scapula to the clavicle and is essential for stabilizing the acromioclavicular joint. The other ligaments either serve different functions or connect different structures.
What is the primary function of the infraspinous fossa on the scapula?
It forms the glenoid cavity
It articulates with the clavicle
It houses the entry of the axillary nerve
It serves as the attachment site for the infraspinatus muscle
The infraspinous fossa is critical as the attachment site for the infraspinatus muscle, which is important for external rotation of the shoulder. The alternative choices do not correspond to its anatomical function.
The suprascapular notch on the scapula is significant because it transmits which structure?
Suprascapular nerve
Axillary nerve
Musculocutaneous nerve
Median nerve
The suprascapular nerve passes through the suprascapular notch, making this an important anatomical landmark. The other nerves do not traverse this notch.
Which of the following movements does the scapula perform during a shoulder shrug?
Retraction
Elevation
Protraction
Downward rotation
During a shoulder shrug, the scapula elevates, moving upward with the shoulder girdle. The other options describe different scapular movements not primarily seen during a shrug.
Which muscle group is primarily involved in retracting the scapula?
Deltoids
Rhomboids
Serratus anterior
Biceps brachii
The rhomboid muscles retract the scapula by pulling it toward the spine. In contrast, the serratus anterior primarily assists in protraction, and the other muscles are not major retractors of the scapula.
How does the morphology of the scapular spine contribute to the attachment of muscles involved in shoulder movement?
It inflects to create a single large muscle attachment area
It fuses with the clavicle to limit shoulder mobility
It provides separate fossae for distinct muscle attachments
It offers no role in muscular attachments
The scapular spine divides the scapula into the supraspinous and infraspinous fossae, creating distinct regions for muscle attachment which enhances shoulder movement. The other options do not accurately reflect the anatomical role of the spine.
A fracture of the inferior angle of the scapula can most significantly impair which shoulder function?
Extension of the wrist
Abduction of the shoulder
Flexion of the elbow
Rotation during arm elevation
The inferior angle of the scapula plays a role in the proper rotation of the scapula during arm elevation. Damage here can disrupt the mechanics of shoulder rotation, whereas the other motions depend on different structures.
Which of the following best explains why abnormalities in scapular positioning can lead to impingement syndrome in the shoulder?
Improper scapular positioning increases blood flow to the shoulder joint
The scapula directly compresses the rotator cuff tendons regardless of position
Abnormal scapular movement improves joint stability, causing stiffness
Altered scapular mechanics can narrow the subacromial space
When the scapula is not positioned correctly, the subacromial space can be reduced, leading to compression of the rotator cuff tendons and subsequently impingement syndrome. The other responses do not accurately describe the biomechanical consequences of scapular malposition.
How might a dysfunction of the serratus anterior muscle indirectly affect the glenohumeral joint?
It can lead to scapular winging, destabilizing the glenohumeral joint
It stiffens the scapular spine, restricting arm rotation
It causes fusion of the acromioclavicular joint
It reduces blood circulation to the arm muscles
Dysfunction of the serratus anterior can result in scapular winging, which disrupts the normal alignment and stability of the glenohumeral joint. The other options do not correctly reflect the impact of serratus anterior impairment on shoulder biomechanics.
Which clinical test specifically evaluates scapular function and helps identify dyskinesis?
Tinel's sign
The Hawkins-Kennedy test
Phalen's maneuver
The scapular dyskinesis test
The scapular dyskinesis test is designed to assess abnormal movement patterns of the scapula and is used to identify dyskinesis. The other tests are associated with nerve compression and impingement syndromes rather than direct evaluation of scapular function.
