Meningeal nerve

Meningeal Nerve

The Meningeal Nerve, as illustrated in Gray's Anatomy.

The Meningeal Nerve is a branch of the trigeminal nerve, specifically the mandibular nerve, that provides sensory innervation to the meninges and parts of the calvaria. It is also known as the recurrent meningeal nerve or nervus spinosus.

Anatomy

The meningeal nerve branches off from the mandibular nerve, passing through the foramen spinosum to reach the meninges and parts of the calvaria. It is typically accompanied by the middle meningeal artery.

Function

The meningeal nerve carries sensory information from the meninges and parts of the calvaria to the brain. This information is primarily related to pain and proprioception.

Clinical Significance

Due to its role in transmitting pain signals, the meningeal nerve is often involved in conditions such as migraines and meningitis. Understanding the anatomy and function of this nerve can aid in the diagnosis and treatment of these conditions.
