WebHistochemical investigations on the mandibular condyle were performed on 72 human embryos and fetuses of crown-rump lengths (CRL) ranging from 26 to 186 mm, representing skeletal maturity indices expressed in CNO values (CNO = composite number of ossified bones in the hand and foot) ranging from 0-0 … WebMuch of classic developmental biology represents careful descriptions of the developing body form, in this case the upper limb. There is a great deal to be learned from this approach. More recent experimental manipulations of limb development are serving to establish the basic processes by which form is generated in each cycle of life.
