XXIII.—The Development of the Anterior Mesoderm, and Paired Fins with their Nerves, in Lepidosiren and Protopterus.
Published online by Cambridge University Press: 06 July 2012
Extract
In a Lepidosiren embryo of stage 20 (Graham Kerr) the mesoderm stretches continuously through the head and trunk regions. In the trunk the dorsal mesoderm is segmented into myotomes, but the segmentation stops short some distance behind the auditory vesicle, leaving unsegmented mesoderm in front of this. In both head and trunk the lateral plate mesoderm is still connected with the dorsal, myotomic or somatic portion.
