M. flexor digito- 

 ruiii brevis (see also 

 Figs. 399 and 400). 

 F r ra : oblunj,' - qua- 

 drangular, thick. Po- 

 sition: in the solo 

 ot the foot, covered 

 only by the aponeu- 

 rosis plantaris ; bound- 

 ed niedianward by 

 the m. abductor hal- 

 lucis, laterahvard by 

 the m. abductor di- 

 o'iti V, dorsalward by 

 the m. (juadratus 

 plantae and tendo 

 in. flexoris digitorum 

 longi. Origin: pro- 

 cessus raedialis tu- 

 ber's calcanei and 

 aponeurosis i^lantaris. 

 Insertion: the fibers 

 diverge in front int(.> 

 four muscular bellies 

 and flat tendons which 

 go to the 2iid 5th 

 toe; the tendons sub- 

 divide at the level of 

 the first phalanx into 

 two processes , per- 

 mitting the corre- 

 sponding tendons of 

 the m. flexor digi- 

 torum longus to pass 

 throughbet ween them , 

 and become attached 

 to the second phalanx. 

 Action: it draws 

 the second phalanx 

 of the 2c^ 5th toe 

 planta rwa rd . Inner- 

 vation: n. plantaris 

 raedialis. 



M. abductor di- 

 git! quiuti (0. T. 

 abductor minimi di- 

 giti) (see also Figs. 

 399, 402 and 409). 

 Form: flatly rounded, oblong. Po- 

 sition: on the lateral margin of the 

 foot, covered only by the aponeurosis 

 plantaris, bounded m'edianward by the 

 mm. flexor digitorum l)revis and qua- 

 dratus plantae. Origin: inferior surface 

 of the calcaneus, aponeurosis plantaris. 

 Insertion: forward and lateralward 

 partly to the tuberositas oss. meta- 

 tarsalis V, partly h\ a half-tendinous 

 insertion to the base of the first pha- 

 lanx of the 5*ii toe. Action: it draws the first 

 plantarward. Innervation: n. plantaris lateralis.
