Retrograde transport of horse radish peroxidase revealed the sources of forming of the initial part of the vertebral nerve in cat. The enzyme was applied on the central region of the nerve near its outlet in ganglion stellatum. Most nerve fibers the vertebral nerve contains are the processes of neurons in ganglion stellatum. Bodies of the labeled neurons in the ganglion are located in the area, attached to the site of the vertebral nerve outlet. It also contains certain number of the afferent fibers of the II-VII thoracic segments spinal ganglia. Axons of motor neurons, the bodies of which are located in ventral cornua of the spinal cord II thoracic segments may also be present. Thus, the cat vertebral nerve is mixed in the site of its forming.
辣根过氧化物酶的逆行运输揭示了猫椎动脉起始部的形成来源。将该酶应用于神经在星状神经节出口附近的中央区域。椎动脉所含的大多数神经纤维是星状神经节中神经元的突起。神经节中标记神经元的胞体位于与椎动脉出口部位相连的区域。它还包含一定数量的胸段Ⅱ - Ⅶ脊髓神经节的传入纤维。其胞体位于胸段Ⅱ脊髓腹角的运动神经元轴突也可能存在。因此，猫椎动脉在其形成部位是混合性的。
