Anatomical terminology [edit on Wikidata] |
The pterygospinous ligament stretches from the upper part of the posterior border of the lateral pterygoid plate to the spinous process of the sphenoid.
Structure
Variation
It occasionally ossifies,[1] and in such cases, between its upper border and the base of the skull, a foramen is formed - pterygospinous foramen (Civinini) which transmits the branches of the mandibular nerve to the muscles of mastication.
