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 ]

definition
  • 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.
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]
has exact synonym
  • primary mandinle
  • cartilago arcus pharyngei primi
  • Meckels cartilage
  • ventral mandibular cartilage
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]
