Morphological Analysis of Chick Embryo Heart Development
It is no longer open to serious doubt that motor root fibers emerging from the neural tube come directly into contact with the somitic mesodermic masses, and in the presence of neural crest cells, exert an inductive influence on the determination of myoblasts (2). A determinant neural influence is also accepted with regard to other muscular structures of non-somitic origin, such as the intrinsic eye muscles. This, indeed, may be felt even earlier than the present evidence shows.
