英语百科

Alar ligament

Atlas-Dreher-Gelenk von oben mit den Flügelbändern, den Ligamenta alaria

The alar ligaments connect the sides of the dens (on the axis, the second cervical vertebra) to tubercles on the medial side of the occipital condyle.

They are short, tough, fibrous cords that attach on the skull and on the axis, and function to check side-to-side movements of the head when it is turned. Because of their function, the alar ligaments are also known as the "check ligaments of the odontoid".
