Meckel's Cartilage
Meckel's cartilage forms in the mesoderm of the mandibular process and eventually regresses to form the incus and malleus of the middle ear, the anterior ligament of the malleus and the sphenomandibular ligament. The mandible or lower jaw forms by perichondral ossification using Meckel's cartilage as a 'template', but the mandible does not arise from direct ossification of Meckel's cartilage.

Famous quotes containing the words meckel and/or cartilage:
“Punishment followed on a grand scale. For ten days, an unconscionable length of time, my father blessed the palms of his child’s outstretched, four-year-old hands with a sharp switch. Seven strokes a day on each hand; that makes one hundred forty strokes and then some. This put an end to the child’s innocence.”
—Christoph Meckel (20th century)
“An English family consists of a few persons, who, from youth to age, are found revolving within a few feet of each other, as if tied by some invisible ligature, tense as that cartilage which we have seen attaching the two Siamese.”
—Ralph Waldo Emerson (1803–1882)
