Nervus spinosus
Updates to Article Attributes
The nervus spinosusspinous (which is also known as the meningeal nerve of the mandibular nerve) is a branch of the mandibular division of the trigeminal nerve which supplies the dura of the middle cranial fossa.
Gross anatomy
The nervus spinosus divides off the mandibular division just below the foramen ovale and just before it branches into anterior and posterior divisons. It ascends to re-enter the head through either the foramen ovale or foramen spinosum. It supplies sensation to the cartilaginous part of the auditory tube and the posterior half of the dura of the middle cranial fossa. The anterior half is supplied by the middle meningeal nerve from the maxillary division of the trigeminal nerve.
The nerve continues to course between the squamous and petrous parts of the temporal bone, entering and supplying the mastoid antrum and the mastoid air cells.
