Guidance of cranial motor axons to their targets conforms to a segmental plan in the chick embryo. Trigeminal motor neurons lie within rhombomeres 2 and 3 and project via an exit point in rhombomere 2 to innervate the first branchial arch. Facial motor neurons lie within rhombomeres 4 and 5 and grow out via an exit point in rhombomere 4 to innervate the… CONTINUE READING
