Arteria vertebralis

Arteria Vertebralis is a major artery in the human body that supplies blood to the posterior part of the brain. It is one of the most important arteries in the body, as it is responsible for supplying oxygen and nutrients to the brain, which is vital for the functioning of the body.

Anatomy

The Arteria Vertebralis originates from the subclavian artery and ascends in the neck to enter the foramen transversarium of the sixth cervical vertebra. It then ascends up to the foramen magnum, where it unites with the artery of the opposite side to form the basilar artery.

Function

The main function of the Arteria Vertebralis is to supply blood to the posterior part of the brain. This includes the cerebellum, the brainstem, and the posterior part of the cerebrum. It also provides blood to the upper spinal cord, the meninges (the protective layers of the brain), and parts of the inner ear.

Clinical Significance

The Arteria Vertebralis can be affected by various medical conditions. These include vertebral artery dissection, which is a tear in the artery wall that can lead to stroke, and vertebral artery stenosis, which is a narrowing of the artery that can reduce blood flow to the brain. Both conditions can cause serious neurological symptoms and require immediate medical attention.
