Pharyngeal Arch Cartilages
Meckel's cartilage - located within the first pharyngeal arch mandibular prominence, forms a cartilage "template" besides which the mandible develops by the process of intramembranous ossification. It is important to note that this cartilage template does not ossify (endochondral ossification) but provides a transient structure where the mandible will form, and later degenerates. The ends of this "U" shaped cartilage form two of the middle ear ossicles (malleous and incus).
Reichert's cartilage - located within the second pharyngeal arch. The ventral portion contributes the superior part of the hyoid cartilage. The ends of this "U" shaped cartilage form the stapes of the middle ear ossicles.
