The skeletal system develops from paraxial and lateral plate (somatic layer) mesoderm and from neural crest. Paraxial mesoderm forms a segmented series of tissue blocks on each side of the neural tube, known as . Intramembranous Bones. Forms many flat skull bones, parts of the mandible, and clavicles..

Bone tissue. , or osseous tissue, is the major component of the skeletal system.. and peripheral blood haematomas for control The transplanted two-day fracture haematoma produced new bone by endochondral ossification at the subperiosteal site, but not at the intramuscular site.
