"the dominant nerve supplying most of the supratentorial dura is the tentorial nerve (a branch of the ophthalmic nerve (CN V1) which supplies the falx cerebri, calvarial dura and superior surface of the tentorium cerebelli."
"Until 2015 it was thought that the meninges lacked their own lymphatic drainage system, but since the groundbreaking work by Antoine Louveau 6 and Aleksanteri Aspelund 9 and their respective teams, functional meningeal lymphatic vessels have been characterised that drain cerebrospinal fluid and immune cells to deep cervical lymph nodes. Subsequent studies have demonstrated these vessels are widespread throughout human dura mater, present along dural sinuses and remote from venous structures, and play roles in waste clearance and neuroimmune surveillance, although further anatomical and functional details continue to emerge 6,7,9,10."
