WebFigure 5. Morphogenetic regulation of somite formation. Recruitment: Somitic mesoderm is recruited from the self-renewing pool of somite precursors in the primitive streak and the tail bud (a). The newly recruited cells are allocated to both bands of paraxial mesoderm and are incorporated into (b) prospective somites (or somitomeres). WebJun 10, 2013 · Origins of skeletal muscles. Vertebrate skeletal muscles originate from four main mesodermal progenitor populations. The presomitic mesoderm (PSM) gives rise to most of the body musculature through the differential contribution of the somitic derivatives; ventral somitic compartments give rise to body wall, limb, tongue and pharyngeal …
