Abstract

The musculature of the pelvic appendage of the Chinese Grouse (Tetrastes sewerzowi) is described in detail. T. sewerzowi exhibits the same features as other tetraonids in the absence of M. adductor digiti II, and the relatively weak development of other intrinsic foot muscles, which are thought to be an adaptation to the extreme cold climate of the habitat of grouse. Myological modifications include weak development of the vincula between the flexor tendons to the digits (M. flexor perforans digiti III and M. flexor perforans et perforatus digiti III, M. flexor digitorum longus, and M. flexor hallus longus), the proximolateral insertion of M. flexor perforans digiti II, the well-developed middle head of M. flexor perforans digiti IV, and the ossification of the insertion tendon of M. extensor brevis digiti IV. These features are suggested to be associated with the requirement of finer control over the individual digits while moving on the tree, especially a thin branch.
