Fig. 1. Composite sagittal view of a 10 mm Human Embryo

(Huber collection No. 3), showing the rhombencephalon and the so-called rhombic grooves, which exist temporarily as transverse furrows in the floor of the ventricle. They are connected by the fifth, seventh, ninth and tenth nerves with the branchiai arches. The fourth groove (d.) is an exception and has no corresponding visceral nerve. Arising from it can be seen the sixth nerve, extending forward to reach the anlage of the external rectus muscle.

Historic Disclaimer - information about historic embryology pages
Pages where the terms "Historic" (textbooks, papers, people, recommendations) appear on this site, and sections within pages where this disclaimer appears, indicate that the content and scientific understanding are specific to the time of publication. This means that while some scientific descriptions are still accurate, the terminology and interpretation of the developmental mechanisms reflect the understanding at the time of original publication and those of the preceding periods, these terms, interpretations and recommendations may not reflect our current scientific understanding.

Online Editor

The author suggests an "estimated age is 31 days", that would be Carnegie stage 14. The appearance of the upper and lower limb buds are more like a later Carnegie stage 16 embryo occurring in week 6, 37 - 42 days, CRL 8 - 11 mm.
