 as well as the caput longum

M. glutaeus minimus 



(see also Figs. 380 and 3S6). 

 Form: flat, triangular. Po- 

 sition: on the lateral surface 

 of the hip, just above the hip- 

 joint; covered by the m. 

 glutaeus medius , in front 

 partly fused with it : bounded 

 in front by the mm. rectus 

 femoris and tensor fasciae 

 latae, behind by the m. piri- 

 formis. Origin: lateral 

 surface of the ala oss. ihum 

 between the linea glutaea 

 anterior and inferior. In- 

 sertion: the fibers converge 

 downward and lateral ward 

 and go with a strong tendon 

 to the anterior surface of 

 the trochanter major femoris 

 (b. irocliauterica m. glutaei 

 minimi see Fig. 380). Action: 

 it abducts the thigh. Inner- 

 vat i o n : n. glutaeus superior. 



M. quadratus femoris 



(see also Figs. 379, 385 and 

 386). Form: flat, quadran- 

 gular. Position: behind 

 and below the hip -joint, 

 bounded in front by the m. 

 obturator externus, below by 

 the m. adductor minimus, 

 behind by the mm. semi- 

 membranosus , biceps and 

 glutaeus maximus, above by 

 the m. gemellus inferior. 

 (Origin: tuber isehiadicum. 

 Insertion: the fibers run 

 para,llel lateralward to the 

 crista intertrochanterica fe- 

 moris. Action: it rotates 

 the thigh outward . Inner- 

 vation: n. tibialis.
