Definition: Any of the approximately 45 bilaterally paired blocks of mesoderm cells, lying on either side of the notochord and neural tube, and forming sequentially starting at the head during development of the embryo. Together they give rise to the axial skeleton (from the sclerotome), associated musculature (from the myotome), and dermis (from the dermatome).
