The brainstem plays a role in regulating several vital functions, including heart rate, eating, sleeping, and breathing. Visual processing takes place in the occipital lobes. Several arteries branch from the basilar artery at the upper portion of the brainstem, delivering blood to various regions of the brain. Two posterior cerebral arteries lead to the temporal lobes important for processing of sounds and the outer layer of the occipital lobes.
A pair of superior cerebellar arteries, another pair of anterior inferior cerebellar arteries, and several paramedian and circumferential pontine arteries also branch from the basilar artery. Cerebellar arteries supply the cerebellum and pontine arteries supply the pons, which relays information between different areas of the brain.
Interruption of the blood flow through the basilar artery can lead to severe brain damage, organ malfunction, or even death. An aneurysm, or bulge in the artery wall, may push that portion of the brain, causing rupture and hemorrhage bleeding. A thrombosis, or blood clot, may block the artery and prevent blood from passing through. Because of its location, as well as the key role it plays in providing oxygen and nutrients to vital portions of the brain, an aneurysm or thrombosis in the basilar artery is particularly dangerous.
In the body there are two deep temporal arteries. These arteries are called the posterior and anterior deep temporal arteries. The brain is one of your most important organs.
The hypothalamus is a small but crucial part of the brain. It controls several important functions, including sleep and growth. Fetal type posterior cerebral artery was noticed in 9. Basilar artery fenestration was noted in 2 percent specimens. Conclusion Basilar artery morphology was studied in 96 human adult cadavers. Variations were noted in its origin, vessel hypoplasia, presence of fenestrations, and fetal patterns.
The data obtained from this study are relevant for anatomists, medical students, interventional radiologists, and neurosurgeons. Related Papers:.
