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 anterior portion of the spinal cord is supplied by the anterior spinal artery. It begins at the foramen magnum where branches of the two vertebral arteries exit, merge, and descend along the anterior spinal cord. As the anterior spinal artery proceeds inferiorly, it receives branches originating mostly from the aorta. [1]
Cervical spinal stenosis is one of the most common forms of spinal stenosis, along with lumbar spinal stenosis (which occurs at the level of the lower back instead of the neck). Thoracic spinal stenosis, at the level of the mid-back, is much less common. [2] Cervical spinal stenosis can be far more dangerous by compressing the spinal cord.
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 ...
At each cervical level, the vertebral artery sends branches to the surrounding musculature via the anterior spinal arteries. Segments of vertebral artery anterior projection. The vertebral artery may be divided into four parts: The first (preforaminal) part runs upward and backward between the anterior scalene and the longus colli muscles.
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]

Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex.
