PRACTICAL ANATOMY. 



on external surface of tuberosity of the ischium ; 

 short head, from the linea aspera about its middle 

 third. 

 Insertion Head of fibula ; it is the outer ham-string 



muscle. 



Nerve Great sciatic. 

 SEMIMEMBRANOSUS. 



Origin The innermost ham- 

 string; from posterior or up- 

 per facet on outer surface, 

 and posterior border of tuber- 

 osity of ischium. 

 Insertion Inserted by three 

 tendons, the inner, attached 

 to inner side of head of 

 tibia ; the middle, blending 

 with the posterior ligaments 

 of the knee-joint ; the outer, 

 inserted above the outer con- 

 dyle of the femur. This ar- 

 rangement of the tendons 

 makes, in fact, the posterior 

 ligament of the knee-joint. 

 Nerve Great sciatic. 

 SEMITENDINOSUS. 



Origin From facets common 



to it and the biceps. 

 Insertion Upper part of inner 



surface of head of tibia. 

 Nerve Great sciatic. 



The biceps is the external ham-string; the serni- 

 membranosus and the semitendinosus are the two 

 internal ham-strings ; they limit the popliteal space 

 laterally.
