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.

Myelinated and unmyelinated nerve fibers may traverse midline structures and terminate opposite to their origin 4. Schematics of the dominant distribution of the NS. B Medial view hewdache the middle cranial fossa. Dural ectasia is the enlargement of the dura and is common in connective tissue disorders, such as Marfan syndrome and Ehlers—Danlos syndrome.

Headache and postcraniotomy pain can be disabling.

Trigemino-cardiac reflex in embolization of intracranial dural arteriovenous fistula. It is likely that the neuropeptide measurements represent local overflow from trigeminal nerves innervating the cerebral and extracerebral circulation. The kater innervation patterns did not follow the course of the frontal branches of the MMA. The trigemino-cardiac reflex headacue Onyx embolization for dural arteriovenous fistula may be caused by mechanical or chemical stimulus to the terminals of the unencapsulated Ruffini-like receptors stemming from A-axons in the dural connective tissue at sites of dural arteries and sinuses.

There appear to be close relationships among the NS, the frontal branches of the MMA, and the pterion, which is a typical landmark utilized in neuroanatomy. A The brain was extracted to expose the middle cranial fossa. During endovascular Onyx embolization for intracranial dural arteriovenous fistula, a trigemino-cardiac reflex has been observed 12. dueal

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 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.


Many medical conditions involve the dura mater. Axon diameters and intradural trajectories of the dural innervation in the rat. Chemical stimulation of the intracranial dura induces enhanced responses to facial stimulation in brain stem trigeminal neurons.

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. Innervation of the posterior fossa dura of the cat.

Innervation of the Cerebral Dura Mater

From this point of view, it has to be assumed that the different terminals have hradache transducer properties despite their rather uniform ultrastructural appearance. Types of stimuli of dural primary afferent neurons To identify the types of stimuli capable of activating meningeal sensory fibers, electrophysiologic recording studies in animals have examined the response properties of primary afferent neurons innervating the cranial dura mater 7.

Loading Stack – 0 images remaining. Diagrammatic representation of a section across the top of the skull, showing the membranes of the brain, etc. To identify the types of stimuli capable of activating meningeal sensory fibers, electrophysiologic recording studies in animals have examined the response properties of primary afferent neurons innervating the cranial dura mater 7.

Fewer mast cells occurred in the skull base dura than in the calvaria dura. Login Register Login using.

Dura mater Meninges of the CNS. Transmitters Several studies have described neuropeptide immunoreactive nerve fibers in the dura mater 9. This study reviews the literature with a focus on the cerebral dura mater innervations. However, unlike in cutaneous afferents, rapid adaptation in dural afferents is associated with very high response thresholds and with rapidly fatiguing responses. Such responses might be suited for signaling transient mechanical stimuli such as would result from sudden head movements.

Innervation of the Cerebral Dura Mater

Check for errors and try again. Response properties of dural nociceptors in relation to headache. Some specimens showed ambiguous dominant bundles of the NS Figures 5B,C or a nonvascular trajectory of nerve fibers to the dural connective tissue Figure 5D. 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.

This study also observed a colocalization of NPY and norepinephrine in some nerve fibers. Effect of sympathetic and parasympathetic mediators on the release of calcitonin gene-related peptide and prostaglandin E from rat dura mater, in vitro. 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 cholinergic innervation of the dura mater in the guinea pig, mouse and rat has been investigated.

Innervation of the meninges | Radiology Reference Article |

The location of the recorded neurons corresponds to the dorsal horn area innergation receives projections from the ophthalmic division of the trigeminal nerve 6which constitutes the primary source of afferents from the supratentorial dura mater 2230 – A functional reflection of this can be seen in studies of neuropeptide release. The only adjective which Celsus applied to headache was “intolerabilis. Vasoactive neuropeptides can be released from perivascular sensory nerves by axon reflex mechanisms in response to a variety of stimuli an axon reflex involves antidromic depolarisation within the collateral branches of a single sensory neuron in response to peripheral stimulation of one branch, e.

Djra Anterior median fissure Anterolateral sulcus Dorsal Posterior median sulcus Posterolateral sulcus. For the supratentorial part the main nerve supply stems from all three branches of the trigeminal nerve. From Wikipedia, the free encyclopedia.

Light and electron microscopic studies of the rat dura mater have shown that peptidergic sensory nerve fibers form a dense network both around blood vessels and in non-vascular regions.

Dura mater

Sensory responses of dural primary afferent neurons Stimulation of dural afferent Snd and greater occipital nerve GON increased the background activity, extended the size of cutaneous trigeminal and cervical receptive fields, and decreased the thresholds to mechanical dural stimulation 24 The projection patterns of the NS on the 44 sides of the dura mater of the middle cranial fossa were innevation according to the trajectories of the nerve fibers.

Sensory Posterior Posterior column-medial lemniscus pathway: The incidence of trigeminocardiac reflex in endovascular treatment of dural arteriovenous fistula with Onyx. Acetylcholinesterase-containing nerve fibers in the dura mater of guinea pig, mouse, and rat.
