Morphogenetic development of trochlear groove and thigh muscles from embryo to fetus in humans
Fig 6
Reconstructed Procrustes shape coordinates for the distal femoral epiphysis.
(A) Distal femoral shape was reconstructed from all specimens and adjusted to size for morphological comparison. (B) The reconstructed Procrustes image shows the formation of the trochlear groove (landmark #2) and sharpness of the peak of the lateral femoral condyle (landmark #1) with increasing crown-rump length (CRL). The numbers next to each dot indicate the landmark number.
