Akromioklavikulargelenk

The video tutorial explains the acromion clavicular (AC) joint, a key component of the shoulder. It describes the joint's structure, including its cartilage and capsule, and its role in shoulder movement. The AC joint is stabilized by two ligaments, which limit its range of motion. The tutorial also covers the joint's movement capabilities, such as the rotation of the clavicle and the tilting of the acromion, highlighting its importance in shoulder mechanics.

What is the AC joint classified as?

• A cartilaginous joint

• A true joint

• A fibrous joint

• A synovial joint

Which bones are connected by the AC joint?

• Clavicle and humerus

• Scapula and humerus

• Sternum and clavicle

• Acromion and clavicle

What is the role of the ligaments in the AC joint?

• To produce synovial fluid

• To connect muscles

• To stabilize the joint

• To allow free movement

Which movement is primarily allowed by the AC joint?

• Ventral and dorsal movement

• Circumduction

• Abduction and adduction

• Flexion and extension

What happens to the acromion when the arm is moved?

• It rotates

• It tilts

• It flexes

• It extends
