do more than suggest to the student that he should early learn to cultivate a

 connective tissue that surrounds all vessels and nerves, and intervenes between 

 muscles. In the sole of the foot you will find, in this order, from without in- 

 ward, the following structures : 



1. The thickest skin of the body on the sole of the foot. 



2. Superficial fascia, very thick, containing granular fat. 



3. The deep or plantar fascia, with its three divisions. 



Abductor minimi digit! 



Flexor brevis minimi digit: 



Tendon of flexor longua diffitorum 



Flexor brevia digitorum 



Abductor hallucis 



Flexor longus hallueis 



Flexor brevis hallueis 

 First lumbriealis 



Tendon of adductor hallucis 



FIG. 271. FIRST LAYER OK THE MUSCLES OF THE SOLE. 



4. Tlie first layer of muscles: The abductor hallucis, the flexor brevis digi- 

 torum, and the abductor minimi digiti. 



5. Tke internal and external plantar nerves and vessels. (Fig. 272.) . 



6. The second layer of muscles : The tendon of flexor longus hallucis and a 

 slip of contribution to the flexor longus digitorum ; tendons of the flexor longus 

 digitorum ; the musculus accessorius and lumbricales ; the nerve- and blood- 

 supply to these muscles. 



7. Tlie third layer of muscles : Flexor brevis hallucis and its sesamoid bones; 

 abductor hallucis muscle ; flexor brevis minimi digiti muscle ; transversus pedis 

 muscle ; nerve- and blood-supply to these muscles.
