OBJECTIVE: Headache and postcraniotomy pain can be disabling. In addition, generation of pain on manipulation of dural membranes during. Activation of dural sensory fibers is regarded as pivotal for the generation of While there is still debate over the initiating events in migraine, it is widely The innervation of the cranial dura mater has been investigated with a. Dura mater, or dura, is a thick membrane made of dense irregular connective tissue that When it covers the spinal cord it is known as the dural sac or thecal sac. The innervation for the infratentorial dura mater are via upper cervical nerves. explain manipulation’s efficacy in the treatment of cervicogenic headache.

Dura mater – Wikipedia

These sinuses drain blood and cerebrospinal fluid from the brain and empty into the internal jugular vein. Frequent mild head injury promotes trigeminal sensitivity concomitant with microglial proliferation, astrocytosis, and increased neuropeptide levels in the trigeminal pain system. Innervation The dominant nerve supplying most of the supratenotrial dura is the tentorial nerve a branch of the ophthalmic nerve CN Va which supplies the falxcalvarial dura and superior surface of the tentorium.

We will be provided with an authorization token please note: Transmitters Several studies have described neuropeptide immunoreactive nerve fibers in the dura mater 9. Capsaicin-sensitive neurogenic sensory vasodilatation in innergation dura mater of the rat. From this point of view, it has to be assumed that the different terminals have different transducer properties despite their rather uniform ultrastructural appearance.

B Medial view of the middle cranial fossa.

Innervation of the meninges | Radiology Reference Article |

PubMed Abstract Google Scholar. Suggest a Research Topic. These findings innnervation that the NS generally travels alongside the course of the frontal branches of the MMA and terminates in the vicinity of the pterion. During endovascular Onyx embolization for intracranial dural arteriovenous fistula, a trigemino-cardiac reflex has been observed 12.


The dura mater has several functions and layers. Anatomy and physiology of head pain. Nerve bundles of the NS terminated at a confluence of the middle meningeal vein and the sphenoparietal sinus, and did not reach the region of the anterior cranial fossa ACF and distal frontal branches of the MMA in the temporal region Figure 2. Our aim was to review the literature regarding the innervation of the cranial dura mater and provide surgical case illustrations to highlight the relevance of such innervation to the neurosurgeon.

These heasache are sometimes found in conjunction with Arnold—Chiari malformation. Read it at Google Books – Find it at Amazon 3.


Innervation of spinal dura mater and dura mater of the posterior cranial fossa. The sensory innervation of the meninges is primarily by meningeal branches of both the trigeminal and vagus nerves with a smaller contribution from the upper cervical spinal nerves 1,2. Innervation of rat and human dura mater and pericranial tissues lf the parieto-temporal region by meningeal afferents.

There are two main dural reflections:. Bull Exp Biol Med. Reappraising the surface anatomy of innervafion pterion and its relationship to the middle meningeal artery.

Axon diameters and intradural trajectories of the dural innervation in the rat. These dural nerves contain myelinated A-axons and unmyelinated C-axons nerve fibers. Intradural procedures, such as removal of a brain tumouror treatment of trigeminal neuralgia via a microvascular decompression require that kater incision is made to the dura mater.

Dura mater

Various clinical manifestations may be linked to this anatomical relationship such as headachestrigeminal neuralgia xura other symptoms that involved the cervical dura. Origin of pain in migraine: Mast cell vasodilatory molecules such as histamine nitric oxide NO, tumor necrosis factor TNF and VIP could participate in the vasodilatory phase of migraine, which is associated with the throbbing pain Bruni JE, Montemurro D. Myelinated and unmyelinated nerve fibers may traverse midline structures and terminate opposite to their origin 4.

B The cranial dura mater was gently detached using an elevator so as to completely obtain the periosteal layer. Parasympathetic transmitters may reduce enhanced nociceptor activity 19 C, cavernous sinus; TG, trigeminal ganglion; black arrow, internal meningeal layer of the cranial dura mater; black triangles, sphenoparietal sinus; white arrow, external periosteal layer of the cranial dura mater.

The supratentorial dura mater membrane is supplied by small meningeal branches of the trigeminal nerve V1, V2 and V3. The trigeminovascular system within the cranial dura mater is a possible cause of headaches.

Others did not form dominant nerve bundles, instead giving off free nerve endings along the course of the MMA or dural connective tissue. Schematics of the dominant distribution of the NS.
