Anatomy of the Human Scapula [+ 3D Model @ 1204]

The video tutorial by Kevin provides an in-depth look at the scapula, covering its structure, movements, and articulations. It explains the roles of shoulder girdle and rotator cuff muscles, and how they interact with the scapula. The tutorial also details the scapula's articulations with the clavicle, humerus, and ribs, and distinguishes between synovial and non-synovial joints. The video includes a visual examination of the scapula's posterior and anterior views, highlighting key features like the spine, acromion, and coracoid process. A 3D model is used to further explore these structures, enhancing understanding of the scapula's anatomy.

What type of bone is the scapula?

• Irregular bone

• Long bone

• Short bone

• Flat bone

Which muscle is responsible for elevating the scapula?

• Serratus anterior

• Trapezius

• Levator scapulae

• Rhomboids

Where do rotator cuff muscles originate?

• Ribs

• Clavicle

• Humerus

• Scapula

What is the primary function of rotator cuff muscles?

• Support the ribs

• Stabilize the clavicle

• Move the humerus

• Move the scapula

Which joint is formed by the articulation of the scapula and clavicle?

• Sternoclavicular joint

• Acromioclavicular joint

• Scapulothoracic articulation

• Glenohumeral joint

What feature is visible in the posterior view of the scapula?

• Coracoid process

• Glenoid cavity

• Scapular spine

• Subscapular fossa

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

• By the position of the coracoid process

• By the direction the spine juts out

• By the size of the glenoid cavity

• By the length of the medial border

What is the function of the suprascapular notch?

• Forms part of the glenoid cavity

• Supports the clavicle

• Connects to the humerus

• Allows passage of the suprascapular nerve

Which structure is a continuation of the scapular spine?

• Acromion

• Inferior angle

• Coracoid process

• Glenoid cavity

What is the significance of the spinal glenoid notch?

• It forms the superior border

• It articulates with the humerus

• It allows nerve and artery passage

• It supports the clavicle
