What is the conoid tubercle of clavicle?
The conoid tubercle also known as the coracoid tuberosity (not to be confused with the coracoid process of the scapula) is a bony prominence on the inferior surface of the lateral third of the clavicle.
What is conoid ligament?
The conoid ligament attaches to the clavicle at the conoid tubercle, which is posterior medial to the trapezoid tubercle. From superior to inferior, the conoid ligament appears as an inferior pointing cone.

What movements occur at the AC joint?
The AC joint is a plane type synovial joint, which under normal physiological conditions allows only gliding movement. As it attaches the scapula to the thorax, it allows an additional range of motion to the scapula and assists in arm movement such as shoulder abduction and flexion.
