The adrenergic nervous plexuses of the pial arteries from 450- to 50 micron in diameter have been studied in dogs, cats and humans from 4 age groups (22-44 years, 55-64 years, 65-74 years and 75-86 years old). It has been found that the decrease in the vessel diameter was accompanied by a marked decline in the absolute number of nervous fibers in the nervous plexuses, however the concentration of the nerve fibers has not revealed any significant differences between human arteries from 450 to 100 micron in diameter and animal arteries from 300 to 80 micron in diameter. The number of varicosities-thickness along the nerve fiber--was the greatest in 200-100 micron human arteries and in 80-60 micron animal arteries. With ageing, the number of varicosities in the adrenergic nervous plexus of human pial vessels decreased faster than in the nerve fibers.
对450至50微米直径的软膜动脉肾上腺素能神经丛进行了研究，研究对象包括来自4个年龄组（22 - 44岁、55 - 64岁、65 - 74岁和75 - 86岁）的犬、猫和人类。研究发现，血管直径减小伴随着神经丛中神经纤维绝对数量的显著下降，然而，直径在450至100微米的人类动脉和直径在300至80微米的动物动脉之间，神经纤维的浓度并未显示出任何显著差异。沿着神经纤维的曲张厚度数量在直径为200 - 100微米的人类动脉和直径为80 - 60微米的动物动脉中最多。随着年龄增长，人类软膜血管肾上腺素能神经丛中曲张的数量比神经纤维中减少得更快。
