LEG AND FOOT. 



FASCIA. 



The superficial fascia is very fatty in the sole of the foot, 

 especially under the tuberosity of the os calcis and balls of the 

 toes, and adheres firmly to the plantar fascia. [376] 



Deep Fascia. About the knee it forms the popliteal fascia 

 behind ; it is attached in front to the patella, ligamentum pa- 

 tellae, and tibial tubercle, and laterally to the tibial tuberosities 

 and head of the fibula, forming the lateral patellar ligaments. 

 In the leg it blends with the periosteum on the inner surface of 

 the tibia and is attached to the lower part of the shaft of the 

 fibula. It sends a septum from the anterior border of the fibula 

 between the peronei and extensors ; and another from the pos- 

 terior border of the fibula between the peronei and flexors; 

 from the latter another septum runs between the superficial 

 and deep flexors. [376] 



At the ankle it is attached to the malleoli and os calcis and 

 strengthened by transverse fibres, forming the annular liga- 

 ments. Of these the internal extends from the inner malleolus 

 to the tuberosity of the os calcis while the external, a smaller 

 thickened band, stretches from the outer malleolus to the os 

 calcis. The anterior is in two parts, viz.: a broad upper band, 

 undefined at its borders, stretching between the malleoli ; and 

 a well-defined lower band which runs inward from the greater 

 process of the os calcis, and divides on the dorsum of the foot 

 into an upper part going to the upper band and internal malle- 

 olus, and a lower part going to the inner border of the fascia on 

 the sole. [377] 



On the sole of the foot it forms the plantar fascia, which con- 

 sists of a central portion and two thin lateral portions. The 

 central portion is a thick triangular band attached to the tu- 

 berosity of the os calcis; this splits in front into five slips 

 which extend to the bases of the toes, joining the digital
