The development of the vertebrate skull

Abstract: IT is more than sixty years (1877) since the appearance of the first general text-book on “The Morphology of the Skull” by Parker and Bettany, a work excellent in its day but now out of date. The most important general work on the subject since then is the part on the development of the skeleton of the head contributed by E. Gaupp to Hertwig's well-known “Handbuch” (1906). It marked a great advance in our knowledge, more especially of the development of the cartilaginous framework of the skull and visceral arches. But a vast amount of work has been done since on the skull, and no one has made more important contributions than Dr. de Beer himself, whose series of detailed studies on the development of the head and skull in various vertebrates from cyclostome to mammal, published from 1922 onwards, form the basis for this fine monograph illustrated by 143 plates containing a vast number of figures most of which are the author's own.The Development of the Vertebrate SkullBy Dr. G. R. de Beer. Pp. xxiv + 552 + 143 plates. (Oxford: Clarendon Press; London: Oxford University Press, 1937.) 30s. net.

The triple origin of skull in higher vertebrates: a study in quail-chick chimeras

Abstract: We have used the quail-chick chimera technique to study the origin of the bones of the skull in the avian embryo. Although the contribution of the neural crest to the facial and visceral skeleton had been established previously, the origin of the vault of the skull (i.e. frontal and parietal bones) remained uncertain. Moreover formation of the occipito-otic region from either the somitic or the cephalic paraxial mesoderm had not been experimentally investigated. The data obtained in the present and previous works now allow us to assign a precise embryonic origin from either the mesectoderm, the paraxial cephalic mesoderm or the five first somites, to all the bones forming the avian skull. We distinguish a skull located in front of the extreme tip of the notochord which reaches the sella turcica and a skull located caudally to this boundary. The former (9prechordal skull9) is derived entirely from the neural crest, the latter from the mesoderm (cephalic or somitic) in its ventromedial part (9chordal skull9) and from the crest for the parietal bone and for part of the otic region. An important point enlighten in this work concerns the double origin of the corpus of the sphenoid in which basipresphenoid is of neural crest origin and the basipostsphenoid is formed by the cephalic mesoderm. Formation of the occipito-otic region of the skeleton is particularly complex and involves the cooperation of the five first somites and the paraxial mesoderm at the hind-brain level. The morphogenetic movements leading to the initial puzzle assembly could be visualized in a reproducible way by means of small grafts of quail mesodermal areas into chick embryos. The data reported here are discussed in the evolutionary context of the ‘New Head’ hypothesis of Gans and Northcutt (1983, Science, 220, 268–274).
