Docent lecture in biology.
Biologists have demonstrated the diversity of developmental patterns in modern vertebrate appendages (e.g. zebrafish, mouse), assuming that they are representative of the group they belong to (respectively, ray-finned fishes and tetrapods). However, it is likely that long-bone microstructures in these models are highly derived and may not reflect their original function. The recent development of high-resolution synchrotron virtual histology has permitted to access the three-dimensional bone microstructure of basal ray- and lobe-finned fishes. Based on illustrated study cases, I will focus on two major points: 1) the origin and development of one of the two processes by which bone is formed in the appendicular skeleton: endochondral ossification; 2) the evolution of bone marrow functions in long bones.
The lecture is an examination to be admitted as a docent and should be at the knowledge level of undergraduate students but could also be of interest to a wider audience. The lecture is 45 minutes and is followed by time for questions and discussion. The lecture will be given in English.
