Which bone do the conoid ligament, trapezoid ligament, and costoclavicular ligament attach to?

The conoid ligament, trapezoid ligament, and costoclavicular ligament all attach to the clavicle, specifically at its medial and lateral aspects where these ligaments provide stabilization to the shoulder girdle.

The conoid and trapezoid ligaments are part of the coracoclavicular ligament complex, connecting the clavicle to the coracoid process of the scapula. This connection plays a crucial role in maintaining the relationship between the clavicle and the shoulder, which is essential for upper limb mobility.

The costoclavicular ligament, on the other hand, connects the clavicle to the first rib, providing additional stabilization to the sternoclavicular joint. This ligamental structure supports the weight of the upper limb and helps maintain proper alignment during shoulder movements.

Other bones listed, such as the humerus, sternum, and scapula, do not have these specific ligaments attaching directly to them, as they play different roles within the shoulder girdle and upper limb structure.
