The Facts on File Dictionary of Biology
Metameric segmentation is most clearly seen (externally and internally) in
annelids; for example, in the earthworm, in which most segments contain blood
vessels, ganglia, nephridia, and muscle blocks. It is also seen in arthropods, but
has ...

1994). Vertebrates also show a high degree of metameric segmentation,
although this is modified somewhat by the presence of the large, regionated
brain and its associated neural-crest-derived structures. Segmentation is more
marked in ...

In Annelida and Arthropoda, metameric segmentation is both internal as well as
external, whereas in Chordata is it less clear externally. External segmentation is
a necessity in Arthropoda so that joints between segments permit movement of ...

METAMERIC SEGMENTATION The term annelida refers to a series of rings of
segments that make up annelid body. These are called metameres or segments.
Annelid body is a linear succession of metameres along the antero-posterior axis
.
This gives the appearance of metameric segmentation, and it is possible that this
represents the beginning of the condition of true metameric segmentation found
in the next phylum, the Appendiculata. It must be noted, however, that there is a ...
