Lateral Plate Mesoderm - Serosal Mesoderms

Serosal Mesoderms

Lateral plate mesoderm gives rise to the serosal mesoderms.

• forms a ventral layer associated with endoderm, the splanchnopleuric mesoderm. This forms the viscera and heart
• forms a dorsal layer associated with ectoderm, the somatopleuric mesoderm. This forms the body wall lining and dermis.
• Abdominal portion becomes contained in dorsal mesentery, part of the serosal mesoderm.
• When the two layers form, a cardiogenic plate is visible. Later, this will form the myocardial primordium, which will contribute to the tubular heart.
