Serial sections of 99 human embryos from Carnegie stages 8–23 were investigated and 38 graphic reconstructions were evaluated. At stage 9 somite 1 is of appreciable size and is separated from the otic disc, as also in the next several stages by rhombomeres and pharyngeal arches 3 and 4, thereby differing from the chick. At stage 10 somite 1 begins to differentiate into sclerotome and dermatomyotome. At stage 11 spinal neural crest begins to develop. At stage 12 parts of somites 1–4 are being… Expand
Segmentation in staged human embryos: the occipitocervical region revisited
TLDR
It is confirmed that the first somite, unlike that of the chick, is separated from the otic primordium by a distance, although the oic anlage undergoes a relative shift caudally. Expand
The Primitive Streak, the Caudal Eminence and Related Structures in Staged Human Embryos
The caudal region of the trunk was reassessed in 52 serially sectioned human embryos of stages 8–23, 42 of which were controlled by precise graphic reconstructions. The following observations, newExpand
The development of the neural crest in the human
TLDR
The first systematic account of the neural crest in the human has been prepared after an investigation of 185 serially sectioned staged embryos, aided by graphic reconstructions and examples of synophthalmia and anencephaly are cited to emphasize the role of the network in the development of cranial ganglia and the skull. Expand
Development of the epaxial muscles in the human embryo
TLDR
The anatomical ontology of the epaxial muscles is determined by craniocaudal and lateromedial gradients in development. Expand
Closure of the vertebral canal in human embryos and fetuses
TLDR
The highly ordered and substantial changes in shape of the vertebral bodies leading to the formation of the spinal canal make the development of the spine an excellent, continuous staging system for the (human) embryo between 6 and 10 weeks of development. Expand
The first appearance of sympathetic ganglia in human embryos at stage 13.
TLDR
It was found that in all embryos, these primordia were present in the thoracic level T4 to T9 and they appeared as scattered aggregates of cells lying dorsally and laterally to the dorsal aortae. Expand
Development of the ventral body wall in the human embryo
TLDR
The data show that the ventral body wall is formed by differential dorsoventral growth in the dorsal part of the body, and that the abdominal muscles expanded ventrally and caudally to form the infraumbilical body wall. Expand
Aberrant differentiation of the axially condensed tail bud mesenchyme in human embryos with lumbosacral myeloschisis
TLDR
Three cases of human embryos with myeloschisis in which the open primary neural tube and the closed secondary neural tube overlap dorsoventrally are reported, suggesting that the AM may not be incorporated into the ventral part of thePrimary neural tube but aberrantly differentiate into the secondary neuraltube containing cavities, leading to dor soventral overlapping of the primary and secondary neural tubes. Expand
Development of the posterior neural tube in human embryos
Development of the posterior neural tube (PNT) in human embryos is a complicated process that involves both primary and secondary neurulation. Because normal development of the PNT is not fullyExpand
Involvement of the axially condensed tail bud mesenchyme in normal and abnormal human posterior neural tube development
TLDR
In embryos with lumbosacral myeloschisis, the AM may not be incorporated into the ventral part of the primary neural tube but aberrantly differentiate into the secondary neural tube containing cavities, leading to dorso‐ventral overlapping of thePrimary and secondary neural tubes. Expand

The early development of the hypoglossal nerve and occipital somites in staged human embryos.
TLDR
It is extremely likely that the hypoglossal musculature in mammals also is derived from occipital somites, and the present study is the first in which this conclusion is adequately supported in the human. Expand
The timing and sequence of appearance of neuromeres and their derivatives in staged human embryos.
TLDR
It is concluded that the precise morphological study of neuromeres in any given species is necessary for correlative investigations of gene expression. Expand
The development of the human brain, the closure of the caudal neuropore, and the beginning of secondary neurulation at stage 12
TLDR
The junction of primary and secondary development (primäre und sekundäre Körperentwicklung) is probably at the site of final closure of the caudal neuropore, which may be important in the genesis of spina bifida aperta at low levels. Expand
The early development of the nervous system in staged insectivore and primate embryos
TLDR
In both nonhuman and human, a tendency is noted whereby the rostral limit of the occipitospinal crest seems to descend relatively at stage 12, and ascend again at stage 13 (at least in the human) to become associated with the appearance of the accessory and hypoglossal nerves. Expand

TLDR
The development and differentiation of the somites with respect to vertebral column formation in avian and human embryos and interactions between notochord and axial mesenchyme are reported on. Expand
The fate of the first avian somite
TLDR
The contribution of the first somite to bones, meninges, dermis and pharyngeal connective tissue is characterised by sharp anterior and posterior boundaries, and other derivatives such as connectives surrounding the vagus nerve, the carotid artery and jugular vein exceed 10 to 18 segments. Expand
Somitic-vertebral correlation and vertebral levels in the human embryo.
TLDR
Somitic and vertebral interrelationships and levels were studied in 84 human embryos of stages 9-23 (3-8 postovulatory weeks) and it was found that the percentages of the total column occupied by the various regions vary from one stage to another. Expand

TLDR
A new system for the exact axial identification of somites and their derivatives from early, embryonic stages of mouse development on (Theiler stages (TS) 15 to TS18‐19) was developed, suggesting a “resegmentation” during SG formation. Expand
Early stages of chick somite development
TLDR
The formation and early differentiation of the somites in the avian embryo is reported on and a method for staging somites according to their developmental age is suggested. Expand
Neurulation in the pig embryo
TLDR
To find a common thread amongst these apparently divergent modes of neurulation another representative mammalian species, the pig, was studied here by scanning electron microscopy, and it is suggested that the somites force the neural folds to elevate precociously. Expand
