Syndetome Formation

A graphical view of syndetome development.

A.  Somite (pink) formed adjacent to the notochord and neural tube (blue and green)

B.  Segmentation of the epithelial somite into the dorsal epithelial dermomyotome (pink) and the ventral mesenchymal sclerotome (purple), in response to signaling from the surrounding tissues.

C.  Subdivision of the dermomyotome into the dermotome (pink) and myotome (lavender).

D.  Formation of the syndetome (yellow) from the ventral sclerotome, as a result of myotomal signaling
