Does Meckel's Cartilage Undergo Intramembranous Ossification?

Its central cartilaginous rod, Meckel's cartilage, is a prominent component of the embryonic lower jaw until it is surrounded by locally formed intramembranous bone, which forms the definitive jaw.

What does Meckel's cartilage gives rise to?

Meckel's cartilage is comprised of three distinct regions. The anterior and posterior regions undergo endochondral ossification and contribute to mandibular development, and to formation of the malleus and incus (ear bones) respectively. The middle region degenerates and gives rise to the sphenomandibular ligament.

Does Meckel's cartilage undergo endochondral ossification?

The distal region of Meckel's cartilage undergoes endochondral ossification contributing to the symphysis of the mandible, whereas the most proximal portion (caudal end) gives rise to malleus and incus through endochondral ossification as well.
