Anatomy | The Scapula and Clavicle

The video tutorial covers the anatomy of the scapula and clavicle, focusing on identifying left and right scapulae, key features like the spine, acromion, and coracoid process, and the fossas that house rotator cuff muscles. It also explains the anatomy of the clavicle, including the acromial and sternal ends, and their articulations with the scapula and sternum.

How can you determine if a scapula is left or right?

• By following the spine out and up

• By measuring the width of the scapula

• By examining the color of the bone

• By checking the length of the spine

What is the acromion?

• A part of the clavicle

• A muscle attached to the scapula

• A cavity in the scapula

• The lateral edge of the scapula's spine

Which structure forms the shoulder joint with the humerus?

• Coracoid process

• Acromion

• Glenoid cavity

• Infraspinous fossa

Which muscle sits in the supraspinous fossa?

• Teres minor

• Infraspinatus

• Supraspinatus

• Subscapularis

What is the function of the rotator cuff muscles?

• To connect the clavicle to the sternum

• To stabilize the elbow

• To perform rotational movements of the shoulder

• To support the rib cage

Which end of the clavicle is flatter?

• Sternal end

• Acromial end

• Medial end

• Lateral end

What does the sternal end of the clavicle articulate with?

• The glenoid cavity

• The coracoid process

• The acromion of the scapula

• The manubrium of the sternum

Which joint is formed by the acromion of the scapula and the acromial end of the clavicle?

• Coracoclavicular joint

• Acromioclavicular joint

• Glenohumeral joint

• Sternoclavicular joint

What is the primary role of the scapula in the shoulder?

• To form the shoulder joint and house rotator cuff muscles

• To protect the heart

• To support the neck

• To connect the ribs

Which of the following is NOT a fossa on the scapula?

• Acromial fossa

• Supraspinous fossa

• Subscapular fossa

• Infraspinous fossa
