sclerotome
Quick Summary
In embryology, a sclerotome is a part of a somite, which are blocklike segments formed from the mesoderm on either side of the embryonic spine. The sclerotome breaks up into mesenchyme and contributes to the axial skeleton of the embryo, specifically the vertebral column, ribs, and parts of the skull. These mesenchymal cells condense to form cartilage around the notochord and spinal cord, which is later replaced by bone.123
