摘要
用家兔小腿三头肌做肌亚部化与运动终板分布的相关性研究。结果表明,家兔腓肠肌外侧头可分为三个肌亚部。腓肠肌内侧头和比目鱼肌无区分亚部的特征。小腿三头肌的神经分支有两型,以Ⅰ型多见(14侧,占87.5％)。腓肠肌外侧头三个亚部各有一支一级神经支和独立的运动终板分布带。这表明,腓肠肌外侧头区分的肌亚部与该肌运动终板的分布具有相关性。用大体解剖法区分的肌亚部可以通过肌运动终板的分布验证。
The correlation between distribution of motor end plates and compartmentalization has been investigated in m. triceps surae of the rabbit. The result shows that the lateral gastrocnemius muscle can be divided into three discrete compartment. The medial gastrocnemius and soleus muscles are simple unipennate muscles and not compartmentalized. Each compartment of the lateral gastrocnemius muscle has a primary nerve branch supple and a distict innervation band. It is suggested that there is a general correlation between distribution of motor end plates and the compartmentalization of a muscle identified by the method of gross anatomy can be proved by the distribution of its motor end plates.
