Abstract
In the literature, there is no information about sexual dimorphism in human muscles. The present work attempts to establish sexual dimorphism in the human gastrocnemius muscle.
In the females, the femora are more oblique at the lower end due to a broader pelvis. To counteract this obliquity, presumably, at the knee joint a stronger muscle mass would be needed on the medial side. To test this assumption the gastrocnemius muscle was studied in 26 male and 25 female cadavers. In each case, the two heads of the muscle were detached from their origins and the length of each head was measured. The study showed that in the female, on the right side, the medial head of the muscle was significantly longer.
