154 MUSCULAR SYSTEM. 



ADDUCTORES FEMORIS. 

 Different anatomists pursue different modes of treating of 

 these muscles ; and all may be proved to be right or wrong, 

 according to the light in which the dissector views the parts, 

 and the artificial divisions which his knife may make of them. 

 One considers the three adductors together, as a triceps muscle ; 

 another describes them as three separate muscles ; while a third 

 looks upon them as forming a single muscle and a biceps. The 

 last mode of proceeding appears to me to be in the most 

 strict accordance with nature, and therefore shall I adopt it 

 here. 



ADDUCTOR BREVIS. 

 ADDUCTOR LONGUS. 



> Suh-pubio-femoratis. 



Situation. — Deep-seated, on the inner part of the thigh. 



Attachment — Superiorly, (both having one common attach- 

 ment) to that part of the pubes included between the symphysis 

 and the acetabulum ; inferiorly, the short adductor is attached 

 to the middle third of the body of the femoral bone ; the long 

 adductor to the lower third of the body of the same bone, and to 

 its internal condyle. 



Relations. — On the outer side with the gracilis ; and on the 

 inner, with the trochanter minor internus. Along their anterior 

 borders run the pectineus and sartorius. Posteriorly, lies the 

 adductor magnus. Between these two adductors pass the femo- 

 ral artery and vein. 



Sti'ucture. — One entire fleshy mass superiorly, split into two 

 portions inferiorly, which at their insertions into the bone mani- 

 fest tendinous fibres. Their surfaces exhibit aponeurotic patches 

 and stripes. 



Action. — Will be considered with the next muscle. 



ADDUCTOR MAGNUS. — Ischio-tibialis. 



Situation. — Postero-internal part of the haunch and thigh ; 

 forming the prominence behind termed ** the point of the 

 quarter." 



Figure. — Irregular. Superior extremity, narrow, pointed, 

 and curved ; from which it becomes broad, thick, and afterwards 

 elongated. The posterior border is thick ; the anterior is thin. 



Attachment. — Superiorly, to the spine of the sacrum and 

 tuberosity of the ischium ; inferiorly, to the lower third of the 

 inner part of the body of the os femoris, to the internal condyle 

 of that bone, and to the inner part of the head of the tibia.
