Introduction to the clavicle

This video tutorial explores the anatomy and function of the acromioclavicular (AC) joint, a synovial joint in the upper arm. It connects the acromion of the scapula with the clavicle and is stabilized by the coracoacromial and coracoclavicular ligaments. The AC joint facilitates various movements of the shoulder and arm, including protraction, retraction, adduction, and abduction. The video also highlights additional resources for further learning, such as interactive quizzes and articles.
