DURAL HEADACHE AND INNERVATION OF THE DURA MATER PDF

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.

Innervation of the Cerebral Dura Mater

The other two meningeal layers are the arachnoid mater and the pia mater. Epidural space Subdural space Subarachnoid space Cerebrospinal fluid. These sinuses drain blood and cerebrospinal fluid from the brain and empty into the internal jugular vein.

Meninges of the CNS. The donors comprised 18 males and 6 females who were aged In addition, a comparatively sparse parasympathetic innervation was described predominantly arising from the ipsilateral sphenopalatine ganglion 34. Consistent with findings dira experimental animals, the present study found that the nerve bundles of the NS in humans usually coursed alongside the MMA. Login Register Login using.

The petrosal branch of the MMA red dots was projected by a distinct meningeal branch red triangle. 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. From Wikipedia, the free encyclopedia.

Increased responses in trigeminocervical nociceptive neurons to cervical input after stimulation of the dura mater.

The NS generally innervayion along the course of the MMA, but was clearly separated from the lateral margin of the middle meningeal vein in a few cases Figure 5A. Schematics of the dominant distribution of the NS. Please review our privacy policy. Articles Cases Courses Quiz. Interneuron Alpha motor neuron Onuf’s nucleus Gamma motor neuron.

Reappraising the surface anatomy of the pterion and its relationship to the middle meningeal artery. Intermediolateral nucleus Posterior thoracic nucleus. 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. In contrast, few studies have macroscopically investigated the trajectory of nerve fibers over long distances of the human cranial dura.

A basement lamella may be completely absent around the axonal terminals.

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. From this point of view, it has to be assumed that the different terminals have different transducer properties despite their rather uniform ultrastructural appearance.

Innervation of the Cerebral Dura Mater

The present study has revealed the macroscopic courses of the NS in the human dura mater. No use, distribution or reproduction is permitted which does not comply with these terms. Neurogenic inflammation has been hypothesized to play a role in headache pathogenesis. Strassman AM, Levy D. Sign in to customize your interests Sign in to your personal account. These conditions are sometimes found in conjunction with Arnold—Chiari malformation.

Effect of acetylcholine on mast cells of the dura mater. Arachnoid granulation Arachnoid trabeculae. Endoscopic cranial base surgery: We will be provided with an authorization token please note: S-HL carried out the experiments, drafted the article and illustrated.

A functional reflection of this can be seen in studies of neuropeptide release. Cisterna magna Pontine cistern Interpeduncular cistern Chiasmatic cistern Of lateral cerebral fossa Matdr cistern Of lamina terminalis. Dunn; Mi Young Toh. The location of the recorded neurons corresponds to the dorsal horn area that receives projections from the ophthalmic division of the trigeminal nerve 6which constitutes the primary source of afferents from the supratentorial dura mater 2230 – Bartsch T, Goadsby PJ.

Rexed laminae Central gelatinous substance Gray commissure. The dorsal rami of the rura three cervical nerves, the ventral rami of the first two cervical nerves, the hypoglossal nerve and recurrent branches of the vagus nerve that innervatiln the posterior meningeal artery provide innervation to the posterior cranial fossa dura mater 5. Myelinated and unmyelinated nerve fibers may traverse midline structures and terminate opposite innfrvation their origin 4.

Substance P immunoreactive fibers occur in the wall of the superior sagittal sinus and the meningeal artery 13 Case illustrations are provided to highlight such innervation patterns.
