407. Bursae and sheaths of tendons of the sole 



of the right foot, injected; sheaths of tendons stained red. 

 (The short muscles of the !* and 2^^ layer have been for the most part removed.) 



Bursa subtendi- 

 nea m. tibialis po- 

 sterioris, frequently 



present , oblong- 

 troughshaped , be- 

 tween the lateral ten- 

 dinous process of the 

 m. tibialis posterior 

 (see Fig. 268) on one 

 side, the ossa navicu- 

 lare and cuneiforme II 

 on the other side. 



Vagina tendinis 

 m. peronaei longi 

 plantaris begins at 

 the sulcus m. peronaei 

 [longi] of the os cu- 

 boideum and ends at 

 about the medial mar- 

 gin of the lig. plantare 

 longum; it communi- 

 cates only rarely with 

 the vagina tendinum 

 ram. peronaeorum com- 

 munis. 



Yagiuae tendi- 

 nnm digitales pe- 

 dis, five, one on the 

 volar surface of each 

 toe: they begin be- 

 hind, at the great 

 toe ui the neighbor- 

 hood of the base, on 

 the other toes in the 

 neighborhood of the 

 heads of the ossa me- 

 tatarsalia , and ter- 

 minate near the ter- 

 minal phalanx; they 

 are surrounded like 

 those in the fingers 

 (see p. 322) by the 

 ligg. vaginalia with 

 tile ligg. cruciata and 

 annularia ; they never 

 commimicate with the 

 sheaths which lie 

 more proximalward. 



Bursae mm. lum- 

 briealium pedis, 

 four, lying on the an- 

 terior extremities of 

 the mm. lumbricales, 

 between tliem and the 

 ligg. capitulorum [oss. 

 metatars.] transversa ; 

 the three medial bursae are almost con- 

 stant, the fourth occurs in half the cases.
