THE LIMBS OF THE HOESE 119 



Dissection.— The deep gluteal muscle must be reflected in order that 

 tbe origin of the rectus femoris and capsularis muscles may be thoroughly 



wifh wivwr^"""'*^ ^'^^'" "°^ *° '"J"'"^ t'^^ capsule of the hip joint, 

 with which the deep gluteal muscle is intimately associated. 



A strong sheet of fascia connects the tensor of the fascia lata with 

 ni.Ll! TV, the ihum, and covers the lateral margin of the iliacus 

 muscle, ihis must be cut away.

M. QUADRICEPS FEMORIS. — Although . named the quadriceps, only 



three heads can be satisfactorily demonstrated. These are the two 



vasti muscles (m. vastus niedialis and m. vastus lateralis), already 



dissected, and the straight muscle of the thigh {m. rectus femoris), now 



to be examined. The fourth head {in. vastus intermedius) is so much 



blended with the medial vastus as to be, to all intents and purposes, 



part of this muscle.
