The meningeal (recurrent) branch of the mandibular nerve (nervus spinosus) is a branch of the mandibular nerve that supplies the dura mater.

Course

The meningeal branch of the mandibular nerve enters the skull through the foramen spinosum along with the middle meningeal artery.

It divides into two branches, anterior and posterior, which accompany the main divisions of the artery and supply the dura mater:

The posterior branch also supplies the mucous lining of the mastoid cells.
The anterior communicates with the meningeal branch of the maxillary nerve.

gollark: Some hardships are really awful and do not give you much feeling of reward for overcoming it. Some you *can't* really overcome (with current technology) e.g. terminal cancer.

gollark: Yes, there is not *actually* any enforced symmetry like this.

gollark: Like how people are mortal and thus decide that death is obviously good because [OBVIOUS RATIONALIZATION] and not evil.

gollark: I mean the generalized thing where once you are in a situation you probably can't escape from you *may* just trick yourself into thinking the situation is cool and good.
