Alar ligament
Encyclopedia : A : AL : ALA : Alar ligament
The alar ligaments connect the sides of the dens (on the axis, or the second cervical vertebra) to tubercles on the medial side of the occipital condyle. They are short, tough, fibrous cords that attach the skull to C1 vertebra and function to check side-to-side movements of the head when it is turned.
The alar ligament is also known as the "check ligament of the odontoid."
