 M. adductor brevis. Form: 

 triangular, tbick. Position: in front 

 covered by the mm. adductor longus 

 and pectineus, above adjoining the m. 

 obturator externus, behind the m. ad- 

 ductor minimus. Origin: anterior 

 surface of the rami ossis j)ubis. In- 

 sertion: diverging downward and 

 lateralward to the labium mediale of 

 the linea aspera femoris. Action: 

 it adducts and flexes the thigh and 

 rotates it outward. Innervation: 

 ramus anterior n. obturatorii. 



M. adductor minimus (0. T. 

 upper iiortii)n of adductor magnus) 

 (see Figs. 380 and 385387). Form : 

 triangular, thick. Position: behind 

 the preceding, bounded above by the 

 mm. obturator externus and quadra- 

 tus i(>moris, below by the m. adductor 

 magnus , behind by the latter and 

 the m. glutaeus maximus. (>rigin: 

 anterior surface of the rami inferiores 

 ossis pubis and ossis ischii. In- 

 sertion: diverging lateralward and 

 downward to the labium mediale of 

 the linea aspera femoris. Action: 

 it adducts and flexes the thigh and 

 rotates it outward. Innervation: 

 ramus posterior n. obturatorii. 



M. adductor magnus (see Figs. 

 376, 378, 380, 384, 386 and 387). 

 Form: triangular, thick. Position : 

 on the medial sule of the thigh, 

 in front covered by the mm. adduc- 

 tores brevis et longus and sartorius, 

 bounded above and in front by the 

 m. adductor minimus, median ward 

 by the m. gracilis and posteriorly by 

 the mm. semimembranosus, semitendi- 

 nosus and biceps. r i g i n : anterior 

 surface of the ramus inferior oss. 

 ischii and tuber ischiadicum. In- 

 sertion: the anterior fibers diverge 

 lateralward and downward to the 

 labium mediale of the linea aspera 

 femoris (see also p. 336), the posterior 

 fibers converge downward to a thick 

 tiMidon, which runs to the epicondylus 

 medialis. Action: it adducts the 

 thigh. Innervation: ramus poste- 

 rior n. obturatorii and n. tibialis. 

 Bursa m. recti femoris, freipiently 

 present, between the tendon of origin of 

 the m. rectus femoris and the acetabulum.
