Meckel's cartilage is the bilaterally paired, rod-like, cartilaginous ventral component of the lower jar, or ventral mandibular arch. It is typically resorbed in adults. [ http://www.ncbi.nlm.nih.gov/pubmed/3693112 http://en.wikipedia.org/wiki/Meckel's_cartilage ]

external definition

Pharyngeal arch cartilage that is the cartilaginous embryonic component of the lower jaw, or ventral mandibular arch. It develops into the endochondral articular and retroarticular bones. Meckel's cartilage is paired.[TAO]

Paired, rod-shaped elements that extend the length of the mandible and lie between the dentaries and the angulosplenials. Can be reduced to various extent in adults.[AAO]

homology notes

In all jawed vertebrates, including fish, the first pharyngeal arch generates the jaw apparatus. The neural crest cells of this arch migrate to form Meckel's cartilage, the precursor of the jaw.[well established][VHOG]
