Tberetiuacula mm. peronaeorum 



are strong bands uf the fascia cruris 

 and fascia dorsalis pedis tthich hold 

 the mm. peronaei firmly in their bony 

 grooves. The superius (see Figs. 393, 

 395 and 409) goes, from the malleolus 

 laterahs, partly into the deep layer of 

 the fascia cruris, partly to the lateral 

 surface of the calcaneus. The inferius 

 (see also Figs. 264 and 4U9) forms a 

 bridge over the mm. peronaei on the 

 lateral surface of the calcaneus, is 

 fastened to the bone above and below 

 them and sends a septum in front 

 between the two to the proc. trochlearis 

 calcanei. Above it is connected with the 

 superhcial layer of the lig. crueiatum. 



Bursa m. bicipitis femoris in- 

 fer 'or (see also Fig. 391), almost con- 

 stant, on the capitulum fibulae between 

 the tendon of the m. biceps feiiioris and 

 tbe lig. eoUaterale fibulare. 



M. tibialis anterior (0. T. tibiaUs 

 anticus) (see also Figs. 391, 401, 402 

 and 405). Form: triangular-prismatic, 

 oblong. Position: superficial on the 

 anterior surface of the leg: bounded 

 medianward by the tibia, lateralward 

 above by the m. extensor digitorum 

 longus, below by the m. extensor hal- 

 lucis longus. Origin: condylus lateralis 

 and facies lateralis tibiae, membrana 

 interossea cruris and fascia cruris. 

 Insertion: the fibers converge down- 

 ward to a flat tendon, which extends 

 medianward, from the lower third of 

 the leg on. in fi-ont of the tibia and 

 articulatio talocruralis through the me- 

 dial compartment of the lig. transversum 

 and of the lig. crueiatum cruris, to the 

 plantar surface of 

 the OS cuneiforme I 

 (b. siihleudiuea in. 

 lihiatis anterioris 

 see Figs. 402 and 

 406) and to the 

 ])lantar surface of 

 the basis oss. me- 

 tatarsalis I (ee 

 also Fig. 268). 

 Action: it flexes 

 the foot dorsal- 

 ward. Inner- 

 vation: n . pe-
