Where are the acromioclavicular (AC) ligaments located?

The acromioclavicular (AC) ligaments are indeed located surrounding the acromioclavicular joint on all sides. This joint is formed between the acromion of the scapula and the clavicle, playing a critical role in stabilizing the shoulder area during upper limb movements. The ligaments help to maintain proper articulation and prevent excessive movement that could lead to dislocation or injury. Their surrounding position around the joint allows them to provide both structural support and stability by limiting movement in a way that protects the joint while still allowing for the necessary range of motion needed in many activities.

The other choices do not accurately describe the location of the AC ligaments. For example, the ligaments do not specifically surround the humeral head, nor are they between the coracoid process and the acromion. Additionally, while the coracoid process does have ligaments that attach to it, describing them solely as attaching to the coracoid process and the clavicle does not encompass the full description or the role of the AC ligaments in surrounding the joint area.
