M. peroiiaeus brevis (see 



Figs. 390 :59(i, 401 , 402 and 

 409). Form: Hat, oblong, penni- 

 1 orin . Position: on th e latera 1 

 side of the leg upon the fibula, 

 partly superficial, partly covered 

 by the m. j^eronaeus longus ; 

 bounded in Iront by the mm. 

 extensor digitorum longus and 

 l)eronaeus tertius, behind by the 

 m. flexor hallucis longus. Origin: 

 fades lateralis fibulae and septa 

 intermuscularia [fibularia]. In- 

 sertion: the fibers converge 

 downward to a tendinous strip; 

 the muscle extends medianward 

 and in front of the tendon of the 

 m. peronaeus longus, in a curve 

 behind and below the malleolus 

 lateralis (in a groove on the same) 

 and then forward, directly upon 

 the lig. calcaneofibtdare and above 

 the proc. trochlearis calcanei; it 

 is held in place by the retinacula 

 ram. peronaeorum; thence the 

 rounded tendon goes downward 

 and forward to the tuberositas 

 OSS. metatarsalis V; it gives off, 

 usually, also a process to the 

 tendon of the m. extensor digi- 

 torum longus going to the little 

 toe. Action: it flexes the foot 

 plantarward and pronates it.

 superficialis. 



The aponeurosis plantaris 

 is a thick layer of glistening 

 tendinous fibers just beneath the 

 skin; it covers the inferior sur- 

 face of the muscJes of the sole 

 (if the foot. It begins at the 

 tuber calcanei, extends forward, 

 diverging, with five processes, 

 and there becomes attached partly 

 to the skin beneath the heads 

 of the ossa metatarsalia , but 

 especially by means of bundles 

 branching off into the depth to 

 go to the ligg. vaginalia. It is 

 strongest in the middle and feebler 

 over the muscles of the great too 

 and of the little toe; it sends 

 tough septa into the depth near 

 the m. flexor digitorum brevis; 

 anei otherwise it is connected behind 



with the fascia cruris and at the 

 sides with the fascia dorsalis 

 pi'ilis. Between its cutaneous insertions, there are 

 stretched out, as in the hand (see p. 317), three bands of 

 fibers whicJi run transversely, the fasciculi t ransversi. 

 Bursa subcutaiioa calcanea see p. 348.
