Epithelial sheet on the external surface of the somite that gives rise to trunk, muscle and dermis.[TAO]

Epithelial sheet on the external surface of the somite that gives rise to trunk, muscle and dermis. Within the dermomyotome there is also a medio-lateral difference. The central region makes dermis, the mesenchymal connective tissue of the back skin. The medial region (closest to neural tube) makes epaxial muscle, and the lateral region (furthest from neural tube) makes hypaxial muscle[http://www.ncbi.nlm.nih.gov/bookshelf/br.fcgi?book=eurekah&part=A66768].

all but the sclerotome of a mesodermal somite; the primordium of skeletal muscle and, perhaps, of the dermis.

Thus, representatives of the agnathan vertebrates, chondrichthyans, and sarcopterygians all have a layer of undifferentiated cells external to the embryonic myotome. In the amniotes, this external cell layer is the dermomyotome. The simplest interpretation of the similar position, morphology, and lack of myosin labeling is that a dermomyotome epithelium is a shared, ancestral vertebrate characteristic.[well established][VHOG]
