Branches of the vertebral artery supply the medulla, the cerebellum, and the spinal cord before merging together to form the basilar artery at the pontomedullary junction. As the vertebral arteries traverse the medulla, each side gives rise to a branch that merges to form the anterior spinal ...
As the bilateral, posteriorly located longitudinal neural arteries regress and join together to form the basilar artery, the lack of regression of these presegmental arteries leads to carotid-basilar anastomoses (persistent trigeminal, otic and hypoglossal arteries) or carotid-vertebral anastomoses (...
Vasculature Segmental arteries and vertebral venous plexus (internal, external) Nerves Meningeal branches of spinal nerves In this article we’ll explore the anatomy and functions of the vertebral column. Contents Vertebrae Typical vertebra Cervical vertebrae Thoracic vertebrae Lumbar vertebrae Sacru...
Between these two layers is the retropharyngeal space, which contains pharyngeal branches of the carotid, palatine, and pharyngeal arteries as well as the pharyngeal veins. Posterior to the prevertebral fascia lies the prevertebral space, at the center of which lies the anterior tubercle of C1....
• Discuss the relationships of the internal jugular vein to other vessels and anatomical structures as it descends from the jugular foramen to the brachiocephalic vein. • Describe the pathways and relationships of the common carotid, external carotid, and internal carotid arteries. • State the...
It is extremely difficult to examine this part of human circulation system, thus numerical experiments may be helpful in understanding the phenomena occurring when two relatively large arteries join together to form one vessel. The obtained results have shown that an individual configuration and ...
