With regards to the viscerocranium components which shares in formation of different structures of the sound transmitting apparatus; the ventral component of the mandibular arch (Meckel's cartilage primordium; M.C.PR) and the dorsal component of the mandibular arch (pterygoquadrate; P.Q) appears as mesenchmatous structures (Figure 2).
