(The m. sartorius has been 

 for the most part removed 

 and a piece has been cut 

 out of the m. rectus fe-

1 . A. epig"astrica in- 

 ferior ((J. T. deep epi- 

 gastric artery) (see Figs. 

 450, 467, 468 and 470) 

 arises just above the lig. 

 inguinale and runs in a 

 A. sperma- curve, first obhquelv me- 

 tica externa (lij^nward, then vertically 

 A. dorsahs i,pv\-ar(l. In its course it 



' Bamus '''^''* ^^ ^^'*^ b(>hind the lig. 

 superfieialis inguinale and lig. inter- 

 Bamus foveolare, medial- from the 

 annulus inguinalis abdo- 

 minalis and, then, passing 

 behind the tendon of the 

 m. transversus abdominis ar- 

 rives at the posterior surface of 

 the m. rectus abdominis. It 

 causes the peritonaeum to bulge 

 forward to form the plica epi- 

 gastrica (see also Figs. 328 and 

 599) and thus separates the 

 fovea inguinalis medialis and 

 the fovea inguinalis lateralis 

 from each other. Finally, it 

 sinks into the substance of the 

 m. rectus abdominis, supplies 

 this muscle and a part of the 

 skin coveringit, and anastomoses 

 freely with the a. epigastrica supe- 

 rior. Branches : 



a) Ramus pubicus (see Fig. 467) 



goes niedianward behind the 

 pelvic attachment of the 

 m. transversus abdominis just 

 above the ramus superior 

 ossis pubis and gives off the 

 ramus obturatorius , which 

 runs downward behind the 

 lig. lacunare [Gimbernati] to 

 the ramus pubicus of the 

 a. obturatoria (see p. 427). 



b) A. spermatica extei-na (0. T. 



cremasteric branch) (in the 

 male) (see Fig. 468), a. li- 

 gamenii terciis xiteri (in the 

 female), perforates the poste- 

 rior wall of the inguinal 

 canal, enters the spermatic 

 cord or the lig. teres uteri 

 and spreads out in the tunics 

 of the testicle, or in the 

 lig. teres and in the labia 

 majora.
