Clavicle Anatomy and Functions

This video tutorial by Matt from Kenhub covers the anatomy, definition, and function of the clavicle, also known as the collar bone. It describes the clavicle's location, its classification as a long bone, and its role in attaching the arms to the trunk. The video highlights key landmarks where ligaments attach, such as the conoid tubercle and trapezoid line. It also explains the clavicle's protective function for neurovascular structures and its role in force transfer. The clavicle's visibility and susceptibility to fractures are discussed. The tutorial concludes with an invitation to explore more resources on Kenhub.

What type of bone is the clavicle classified as?

• Short bone

• Flat bone

• Long bone

• Irregular bone

Where is the conoid tubercle located on the clavicle?

• Near the sternal end

• Near the acromial end

• In the middle of the clavicle

• On the superior surface

Which ligament attaches at the impression on the sternal end of the clavicle?

• Costoclavicular ligament

• Coracoclavicular ligament

• Glenohumeral ligament

• Acromioclavicular ligament

What is one of the primary functions of the clavicle?

• To aid in breathing

• To support the skull

• To attach the arms to the trunk

• To protect the heart

How does the clavicle contribute to the protection of the arm?

• By forming a shield over the arm

• By transferring force from the arm to the axial skeleton

• By being a part of the rib cage

• By being a part of the shoulder joint

Why is the clavicle easily palpable?

• Because it is covered by many muscles

• Because it lies close to the surface of the body

• Because it is located deep within the body

• Because it is a very thick bone

What is the most common reason for clavicle fractures?

• Its location and function as a stress absorber

• Its role in supporting the head

• Its involvement in the shoulder joint

• Its connection to the rib cage
