==Limb Muscle Development==

 +
*Skeletal muscle of the limbs originates from those somites closest to the limbs.
 +
#Signalling factors from the limbs cause cells to migrate from the somite.
 +
#*Singalling factors cause the hypaxial lamina to break down.
 +
#*This allows cells to migrate.
 +
#*''Few cells migrate; but they rapidly prolifate during migration to increase cell numbers.''
 +
#Muscle precursors migrate into the limb bud (proliferating).
 +
#*At the proximal region of the limb, two populations of cells exists.
 +
#*These are the dorsal and ventral masses.
 +
#Cells continue migration within these populations.
 +
#Once cells have reached their destinations, they differentiate.
