/, Strin-ttirr. ,IH, J Attachment* <///// ,</ neuron* Tie apom-un.sis is 

 irregularly triangular, and formed of nacrous looking fibres, uhicli an- 

 din ct.-d like the muscular til>r t s, and cr 

 in X fashion the aponciirotic fibres of 

 the external oblique. It succeeds tin- aii- 

 d IM inferior border of the muscular por- 

 tion, and is separated, superiorly, into 

 :al digitations which reach the in- 

 ternal face of the last asternal cartilages. 

 Throughout the whole extent of its in- 

 ternal harder it is fixed to the white line. 

 //' lit/inn*. This muscle is covered 

 ii-rnal oblique. The aponcuroses 

 of the two muscles, which are merely 

 superposed outwardly, are blended in- 

 uaidly in s > intimate a manner that it 

 might IMJ thought their respective fax-i- 

 culi were \M.\VII into each other. Tho 

 -mall oblique cuvers the great straight 

 and the transverse muscles. 



Ai-tiini. This muscle, a congener of 



the preceding, compresses the abdominal 



ihe last ribs, and causes 



the ilexion. either direct or lateral, of the 



i.ral column. 



Tin f ti-'ii-hn- iniixrli- f tlif last rib. - 

 This small muscle, flattened on each side, 

 and triangular in form, originates by 

 apoiieiirotic tibres from the summits of 

 the first two or three transverse proe< ! 

 of the lumbar region. It terminates on 

 the PI.-I. rii.r border of tho last rib. 

 M d by the last digitation of the pos- 

 i ratus and by the gnat olili<|ue, 

 it covers in turn the transverse muscle of 

 tin- abdnmt-n. In contracting, it draws 

 the last rib backwards, and fixes it in 

 that position, in order to permit the ex- 

 piratory action of the internal int'-n-o-tal 

 It therefore plays the same 

 part, in ivi-anl to these muscles, that the 

 to tin- external intercostal 

 IM (Fig. 106, 17).
