 tendons of the ankle pass beneath the uppermost one, and the 

 anterior tibial vessels and nerve pass over it.

 Plantar Fascia attached to the tuberosity of the os calcis ; an- 

 teriorly it spreads out and divides into five slips, which are 

 attached to the digital sheaths of the toes. From the sides a 

 thinner layer of fascia spreads out to cover the muscles and 

 sends in intermuscular septa. The plantar fascia is instru- 

 mental in preserving the arch of the foot.
