THE MUSCLES OF THE LOWER EXTREMITY. 243 



the last-described muscle close up to its head. It is 

 considerably smaller in size, and its outer fascia sooner 

 terminates in its flattened tendon. This takes its course, 

 as I have already described, closely applied to the 

 flexor perforatus annularis primus pedis, through 

 the tibial cartilage and hypotarsus of the tarso-meta- 

 tarsus. Arriving at the palmar aspect of the basal 

 joint of the third toe, it sends down a slip to either 

 side of its shaft, which thus forms a guide for the 

 passage of the two deeper flexors which glide between 

 them. 



The carneous portions of the three last-described 

 muscles are quite intimately bound together by a 

 close-fitting and firm fascia. So that there is con- 

 siderable unison in their action, but, as we have seen, 

 the course of their tendons is more or less independent. 

 If it were possible to keep the distribution and in- 

 sertion of these tendons in our mind, it would not be 

 far out of place to speak of their common muscular 

 portion as the flexor perforatus primus pedis.
