Abstract

Ultrastructure of the nerve apparatus in the arteries of the brain base has been studied in cats. The structure of peri- and adventitial nerves has been investigated electron microscopically. Three types of efferent axons and four types of synaptic vesicles (small agranular and granular, large granular, large electron opaque vesicles) have been revealed. Vesicle-containing axons in the brain arteries approach the external smooth muscle cells of about 80 nm. Terminal axonal dilatations possessing direct and mediated connections with muscular cells of the middle tunica have been revealed.

摘要

对猫脑基底动脉神经装置的超微结构进行了研究。用电镜研究了血管周围神经和外膜神经的结构。发现了三种传出轴突类型和四种突触小泡类型（小无颗粒和有颗粒的、大颗粒的、大电子不透明小泡）。脑动脉中含有小泡的轴突接近约80纳米的外平滑肌细胞。已发现终末轴突膨大与中膜肌细胞存在直接和间接连接。
