PLANTAR FASCIA. 291 



nular ligaments ; on the inner side with the middle portion, and exter- 

 nally with the dorsal fascia. 



Besides constituting a strong layer of investment and defence to the 

 soft parts situated in the sole of the foot, these three portions of fascia 

 send processes inwards, which form sheaths for the different muscles. 

 A strong septum is given off from each side of the middle portion of 

 the plantar fascia, which is attached to the tarsal bones, and divides 

 the muscles into three groups, a middle and two lateral ; and trans- 

 verse septa are stretched between these to separate the layers. The 

 superficial layer of muscles derive a part of their origin from the plan- 

 tar fascia.
