160 MUSCLE TISSUE 



The deep fascia or fascia lata is a strong membrane 

 forming a continuous sheath around the limb. It 

 descends on the gluteus medius as far as the upper 

 border of the gluteus maximus, which muscle it encases, 

 and over the great trochanter a great part of the muscle 

 is inserted between its layers. From the forepart 

 of the iliac crest to the outer tuberosity of the tibia 

 is the iliotibial band, which receives the insertions 

 of the tensor vaginae femoris and gluteus maximus 

 muscles. 



The fascia lata has various deep processes; one is 

 internal to the tensor vaginse femoris on the surface 

 of the vastus externus. 



There are external and internal intermuscular septa 

 inserted into the linea aspera. 



The Gluteal Region (Buttocks) 



Gluteus Maximus. A quadrilateral, very coarse 

 muscle. Origin, posterior fourth of the external lip 

 of the iliac crest and rough surface between it and the 

 posterior gluteal line, the last two pieces of the sacrum 

 and first three of the coccyx, great sacrosciatic liga- 

 ment, and aponeurosis of the erector spinse. 



The upper half and superficial fibers of the lower half 

 are inserted into the fascia lata and continued into the 

 iliotibial band; the deeper portion of the lower half 

 into the gluteal ridge on the upper third of the shaft 

 of the femur. 



Gluteus Medius. Origin, ilium between the crest, 

 the posterior and middle curved lines, and from the 

 fascia covering it; to insert on the outer surface of the 

 great trochanter; a small bursa between the bone and 

 tendon. 



Gluteus minimus is covered by the preceding, and 

 arises from the whole surface on the ilium between the 

 middle and inferior curved lines, fibers converge into 

 an aponeurotic tendon on the outside of the muscle,
