Description[edit | edit source]
The ligamentum nuchae is continuous with the supraspinous ligament[1][2]. It forms a two-layered fibroelastic septum. This septum consists of the dorsal raphe and medial septal part[1]. It stretches during flexion and its elasticity helps bring the head back to an upright position[2].
Origin[edit | edit source]
The external occipital protuberance[1][2]. The deep fibers of the ligament attach to the external occipital crest and the posterior tubercle of the atlas[3]. It also blends into the posterior atlanto-occipital membrane and the posterior atlanto-axial membrane[1].
Insertion[edit | edit source]
Function[edit | edit source]
Limits hyperflexion of the neck[1][3].
Provides an attachment for trapezius and splenius capitis.
