Anthropomorfology of extensor muscles of carpus, the long and short radial (mm. extensores carpi radiales longus et brevis) in fetuses

Abstract

Radial extensores of carpus the long and short one in 32 human fetuses were prepared that had Si 175-330 mm. The muscles showed insertions and shape that are characteristic of adult subjects.

For both the muscles 5 indices were calculated and it was found that in the investigated period only a slight acceleration of growing in length of the fleshy part occured. No distinct sex dimorphism nor asymmetry in build was observed.
