The fascia on the sole of the foot is called the plantar fascia (Plate LV.) 

 and is the densest of all the fibrous membranes. It is divided into three por- 

 tions. (1) A central portion which is attached to the inner tuberosity of the OS 

 calcis and runs forward below the Flexor brevis digitorum and ends in front in 

 a process for each toe and in slips for the skin. At its sides it joins the lateral 

 portions which extends around the margins of the foot. At the junction of the 

 central with the two lateral portions expansions pass upward. (2) The ex-

tenia] portion which is thin in front and thick behind extends from the os calcis 

 io the base of the fifth metacarpal hone. It coversthe nude'- surface ofthe Ab- 

 ductor minimi digiti. It is continuous with the fascia on the hack of the fool 

 and with the central portion of the plantar fascia. (3) The internal lateral 

 portion covers the Abductor hallucis muscle and is quite thin. Posteriorly it 

 is attached to the internal annular ligamenl and continues around the side of the 

 foot with the dorsal fascia, and e\l< rnally with the middle portion of the plantar 

 fascia.
