Detailed explanation-1: -Branchial arches 1 and 2 are referred to as the mandibular and hyoid arches, respectively. Each of the arches is lined internally by endoderm and externally by ectoderm tissue. Between the endoderm and ectoderm lies the mesenchyme, composed of both mesoderm and neural crest tissue.

Detailed explanation-2: -The first branchial arch (Meckel’s) cartilage is the position of the future mandible, as well as the eventual malleus and incus. The second branchial arch cartilage produces the stapes, the styloid process, the stylohyoid ligament, and the superior portion of the body of the hyoid.
