The meningeal branches of vertebral artery (posterior meningeal branch) springs from the vertebral opposite the foramen magnum, ramifies between the bone and dura mater in the cerebellar fossa, and supplies the falx cerebelli. [1] [2] [3] It is frequently represented by one or two small branches.
The leptomeningeal collateral circulation (also known as leptomeningeal anastomoses or pial collaterals) is a network of small blood vessels in the brain that connects branches of the middle, anterior and posterior cerebral arteries (MCA, ACA, and PCA), [1] with variation in its precise anatomy between individuals. [2]
The posterior meningeal artery is one of the meningeal branches of the ascending pharyngeal artery (and is typically considered the terminal branch of said artery). It passes through the jugular foramen to enter the posterior cranial fossa. [1] It is the largest vessel supplying the dura of the posterior cranial fossa. [citation needed]
The falx cerebri is a strong, crescent-shaped sheet of dura mater lying in the sagittal plane between the two cerebral hemispheres. [3] It is one of four dural partitions of the brain along with the falx cerebelli, tentorium cerebelli, and diaphragma sellae; it is formed through invagination of the dura mater into the longitudinal fissure between the cerebral hemispheres.
The middle meningeal artery is the largest of the three (paired) arteries that supply the meninges, the others being the anterior meningeal artery and the posterior meningeal artery. The anterior branch of the middle meningeal artery runs beneath the pterion. It is vulnerable to injury at this point, where the skull is thin.
The ascending pharyngeal artery is an artery of the neck that supplies the pharynx. Its named branches are the inferior tympanic artery , pharyngeal artery, and posterior meningeal artery . inferior tympanic artery , and the meningeal branches (including the posterior meningeal artery ).
In fact, acute sulcal artery syndrome should be suspected in patients with acute hemicord syndrome, and vertebral artery dissection should be suspected in cases of high cervical cord involvement. In a recent review by Tan YJ, et al. in 2021, good functional recovery was seen in most, and vertebral artery dissection was the leading cause of ...
Such severe spinal stenosis symptoms are virtually absent in lumbar stenosis, however, as the spinal cord terminates at the top end of the adult lumbar spine, with only nerve roots (cauda equina) continuing further down. [15] Cervical spinal stenosis is a condition involving narrowing of the spinal canal at the level of the neck.
