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
An immunocytochemical electron microscopy study found different unmyelinated axons in one Schwann cell may contain nerve fibers with VIP, Substance P and NPY immunoreactivity. National Center for Biotechnology InformationU. A functional reflection of this can be seen in studies of neuropeptide release. Related Radiopaedia articles Anatomy: The interface with the frontal branches of the MMA and the sphenoparietal sinus coincides with the pterion green linewhich is the region where the frontal Fparietal Psphenoid S and squamous parts of the temporal bones T join together.
Some neurons also respond to thermal stimuli, in either the warming or cooling direction. Stimulation of the middle meningeal artery leads to Fos expression in the trigeminocervical nucleus: The dura-muscular, dura-ligamentous connections in the upper cervical spine and occipital areas may provide anatomic and physiologic answers to the cause of the cervicogenic headache.

A rupture of a bridging vein causes a subdural hematoma. Subarachnoid hemorrhage in the rat substantially reduced the SP-immunoreactive nerve fibers of the dura mater, but left the CGRP-immunoreactive innervation unchanged. This study also observed a colocalization of NPY and norepinephrine in some nerve hte.
From this point of view, it has to innrvation assumed that the different terminals have different transducer properties despite their rather uniform ultrastructural appearance.

Arborized fibers from the meningeal origin without dominant bundles were distributed to all branches of the MMA equally in Nerve fibers projected to the course of the frontal branches of the MMA to form distinct nerve bundles sending collaterals in Chemical stimulation of the intracranial dura induces enhanced responses to facial stimulation in brain stem trigeminal neurons.
Localization of pterion in neonatal cadavers: Check for errors and try off. Besides activating the neurons, the inflammatory mediators produced ueadache sensitization, or enhancement, of responses to mechanical stimuli.
DURAL HEADACHE AND INNERVATION OF THE DURA MATER
Neurons could also be activated by dural application of a number of algesic agents, including potassium chloride, capsaicin, buffer solutions of low or high osmolarity, or a mixture of inflammatory mediators bradykinin, PGE2, serotonin, histamine. For instance, these terminals are the best candidates to sense the composition of the blood and the exchange of fluid at the post-capillary venule 4.
