"The ligamentum nuchae consists of the dorsal raphe and medial septal parts. The dorsal raphe attaches to muscles while the medial septum does not."
Expected headings
"Dorsal raphe"
"Medial septum"
"The medial septum extends from the ventral surface of the dorsal raphe. The medial septum isolates the semispinalis capitis ventrally and laterally. Thus, the semispinalis cervicis, multifidus and opposite semispinalis capitis remain separate."
