Abstract
A method is described for counting the total number of fibres in skeletal muscles. The motor nerve fibers and muscle fibers have been counted in 5 examples of M. soleus and 3 examples of M. extensor longus digitorum of the cat. The fiber of "red" muscle has been found stronger and of greater density than the fiber of "white" muscle. "Innervation ratio" has been defined as the ratio of the number of motor nerve fibers supplying a given muscle to the number of its muscle fibers. An innervation ratio of about 1: 120 has been found for M. soleus, and 1: 165 for M. extensor longus digitorum.This publication has 4 references indexed in Scilit:
