Abstract

The density and pattern of the noradrenergic innervation of the main extramedullary blood vessels of the rat spinal cord was studied using combined glyoxylic acid histofluorescence and quantitative image analysis techniques. The anterior spinal artery has a perivascular plexus of fine noradrenergic nerves rich in varicosities; the central artery has nerve fibers of various sizes; and the posterior spinal vein has a limited plexus of noradrenergic nerve fibers. The possible significance of the noradrenergic innervation of extramedullary spinal cord blood vessels is discussed.

摘要

采用乙醛酸组织荧光和定量图像分析技术相结合的方法，研究了大鼠脊髓主要髓外血管的去甲肾上腺素能神经支配的密度和模式。脊髓前动脉有一个富含曲张体的细小去甲肾上腺素能神经的血管周围丛；中央动脉有各种大小的神经纤维；脊髓后静脉有一个有限的去甲肾上腺素能神经纤维丛。讨论了脊髓髓外血管去甲肾上腺素能神经支配的可能意义。
