  4. Origin of Limb Muscles Dorsal muscle mass forms extensors and supinators in upper limb, extensors and abductors in lower limb. Ventral muscle mass forms flexors and pronators in upper limb and flexors and adductors in lower limb. Morphogenesis guided by CT, not myoblasts Split into individual muscles, cell death involved Carlson l999 Human Embryology Larsen 1993
