Proposed pathogenesis of median clefts of the lower lip and mandible include, hypoplasia of the mandibular processes either during the early embryonic period or during late embrayonic periods.
In breast muscle of chickens, the transcript abundance of HDAC2 increased significantly across embryonic periods (ED 14, 16, 18, and 21) and there were differences between all sampling stages (ED 14 to 16, ED 16 to 18, and ED 18 to 21) (Figure 1).
Many different investigations are done about the ossification centers in embryonic period that are about all mesenchymal, cartilaginous and ossification stages [14, 27].
Developmental mode in opisthobranchs is most reliably documented when based on observations of the morphology of hatching veliger larvae--particularly the presence or absence of eyespots and propodium--accompanied by measurements of egg size, embryonic period and temperature, and size and type of shell at hatching (Bonar 1978; Goddard 2004).
Until recently we thought that all of these nerve cells were generated during the embryonic period and so the circuitry that controls appetite was fixed.
If you prepare several ex ovo embryos, a few are likely to survive most of the embryonic period and this can continue to be a valuable science project, particularly if you consider every event to be a teachable moment.
We evaluated the duration of pre-oviposition and oviposition periods, the total and daily production of eggs, the viability of eggs (hatchability [%]), the duration of the embryonic period and longevity of males and females.
