- n. A long muscle of the back of the thigh, or postfemoral region, arising form the ischial tuberosity, and inserted chiefly into the back part of the inner tuberosity of the tibia: so called from its semmem-branous character in man, retained in few other animals.

Branches supply the following muscles -- obturator, semimembranosus (adductor magnus), biceps femoris (triceps abductor femoris), semitendinosus (biceps rotator tibialis), lateral extensor
The adipose substance, which is here generally abundant, should now be divided, between the mesial line and the semimembranosus, till the sheath of the vessels be exposed.
While the risk of exposure to CWD infectivity following consumption of prions in muscle is mitigated by relatively inefficient prion transmission via the oral route (8), these results show that semitendinosus/semimembranosus muscle, which is likely to be consumed by humans, is a significant source of prion infectivity.
To test whether skeletal muscle of diseased cervids contained prion infectivity, Tg (CerPrP) 1536 mice (2) expressing cervid prion protein (CerPrP), were inoculated intracerebrally with extracts prepared from the semitendinosus/semimembranosus muscle group of CWD-affected mule deer or from CWD-negative deer.
Semitendinosus/semimembranosus muscle was also obtained from two asymptomatic, mock inoculated deer, referred to as FPS 6.68 and
