Investigations were performed in 36 rats of Wistar strain. In 50% of cases the accessory arteries originating from the vertebral artery and connections of the ventral spinal artery with the first radicular arteries were found. The dorsal spinal arteries always originated from the intracranial part of the vertebral artery, and in many instances their discontinuity at the level of C4--C6 was observed. Besides the spinal arteries the cervical part of the spinal cord is supplied by radicular arteries which are more frequent in rats than in human.
对36只Wistar品系大鼠进行了研究。在50%的病例中，发现了起源于椎动脉的副动脉以及腹侧脊髓动脉与第一根神经根动脉的连接。脊髓背侧动脉总是起源于椎动脉的颅内部分，并且在许多情况下，观察到它们在C4 - C6水平处中断。除了脊髓动脉外，脊髓颈段还由神经根动脉供血，这些神经根动脉在大鼠中比在人类中更常见。
