THE MUSCULATURE 



an anterior and a posterior. Very frequently from the anterior margin of the muscle a special 

 fasciculus is more or less isolated (the scansorius, invertor femoris, small anterior gluteal, etc.). 

 The accessorius of the gluteus minimus is a small muscle fasciculus which may he under cover 

 of the gluteus minimus and extend to be inserted into the capsule of the hip-joint. 



BURS^ 



B ischiadica m. glutei maximi. — A small inconstant bursa between the tuber ischii and 

 the gluteus maximus muscle. B. trochanterica m. glutei maximi.— A large bursa constantly
