THE LIMBS OF THE HOESE

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

 the origin of the rectus femoria and capsularis muscles may be thoroughly 

 exposed. Care must be taken not to injure the 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 

 the border of the ilium, and covers the lateral margin of the iliacus 

 muscle. This 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 medialis and m. vastus lateralis), already 

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

 to be examined. The fourth head (m. vastus intermedins) is so much 

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

 part of this muscle.
