Spinaalses

Spinaalses, also known as spinal arteries, are a set of arteries that supply blood to the spinal cord. They are branches of the vertebral arteries, which are themselves branches of the subclavian arteries. The spinaalses are typically divided into three segments: the cervical, thoracic, and lumbar segments, corresponding to the regions of the spine.

The cervical spinaalses arise from the vertebral arteries and supply blood to the upper part of the spinal cord. The thoracic spinaalses arise from the intercostal arteries and supply blood to the middle part of the spinal cord. The lumbar spinaalses arise from the aorta and supply blood to the lower part of the spinal cord.

Spinaalses play a crucial role in maintaining the health and function of the spinal cord. They provide oxygen and nutrients to the spinal cord, which is essential for its proper functioning. Any disruption or damage to the spinaalses can lead to spinal cord ischemia, a condition characterized by reduced blood flow to the spinal cord, which can result in paralysis or other neurological deficits.

The diagnosis and treatment of spinaalses-related conditions typically involve imaging studies, such as magnetic resonance angiography (MRA) or computed tomography angiography (CTA), to visualize the arteries and assess their condition. Treatment options may include surgical intervention, such as endarterectomy or stenting, to restore blood flow to the spinal cord.
