Tlie miter branch pierces the sartorius ami both become cutaneous about the junc- 

 tion of the. upper and middle thirds of the thigh (ligs. fiV.I and (i'.H). They deM-end 

 along the inner part of the front of the thigh to the knee, supplying the skin in tin- 

 lower two-thirds of the inner part of the front of the thigh, and their terminal fila- 

 ments take part in the formation of the patellar plexus. About the middle of the 

 thigh it often communicates with the lumbo-inguinal nerve (crural branch of the 

 genito-crural nerve). The internal cutaneous nerve runs downwards and inwards

along the outer side of the femoral artery, to the apex of the femoral trigone (Scarpa's 

 triangle), where it crosse* in front of the artery and divides into an anterior and a 

 posterior terminal branch. Hefore this division takes place, however, two or three 

 collateral branches are given off from the trunk. The highest of these passes through 

 the fossa ovalis ( saphenons opening), or it pierces the deep fascia immediately below 

 the opening, and supplies the skin as low as the middle of the thigh. The lowest 

 pierces the deep fascia at the middle of the thiirh and it descends in the subcutaneous 

 tissue, supplying the skin on the inner side of the thiirh from the middle of the tliisrh
