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. The distal end of Meckel's cartilage ossifies to form the malleus and most of the rest disappears in development, with the part adjacent to the malleus being replaced by fibrous membrane comprising the sphenomandibular ligament and the connective tissue covering most of the remaining part ossifying to form much of the mandible.
