Nerve bundles of dhral 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.

Innervation of the Cerebral Dura Mater

Arborized nerve fibers crossed the wall of the MMA and traveled along the opposite wall of the middle meningeal vein. Received Feb 22; Accepted Apr Sang-Don Han, hihanol kku. 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.

The headacje agent carbachol did not change basal release of CGRP or PGE2, whereas it diminished release induced by a mixture of inflammatory mediators.

Dural ectasia is the enlargement of headachr dura and is common in connective tissue disorders, such as Marfan syndrome and Ehlers—Danlos syndrome. The dura mater has several functions and layers. Please review our privacy policy.
