Meckel's cartilage

In modern mammals, the Meckel's cartilage appears during development but disappears before adulthood.

Meckel's cartilage A cartilaginous bar from which the mandible is formed.

The ligament is derived from Meckel's cartilage.

Instead, their lower jaw is composed of a cartilagenous structure homologous with the Meckel's cartilage of other groups.

These are ossified portions of cartilage - called Meckel's cartilage - that are attached to the jaw.

In some fishes, the palatoquadrate is the dorsal component of the mandibular arch, the ventral one being Meckel's cartilage.

Ossification takes place in the membrane covering the outer surface of the ventral end of Meckel's cartilage (Figs.

By the tenth week the portion of Meckel's cartilage which lies below and behind the incisor teeth is surrounded and invaded by the membrane bone.

This arch originates maxillar and mandibular prominences, part of the temporal bone and Meckel's cartilage (malleus and incus) as skeletal structures.

Pharyngeal arches appear in all tetrapod embryos: in mammals, the first pharyngeal arch develops into the lower jaw (Meckel's cartilage), the malleus and the stapes.

The Ossification of the mandible refers to the Human mandible laying down new bone material in the fibrous membrane covering the outer surfaces of Meckel's cartilages.

PAX7 is expressed in the palatal shelf of the maxilla, Meckel's cartilage, mesencephalon, nasal cavity, nasal epithelium, nasal capsule and pons.

The Meckelian Cartilage, also known as "Meckel's Cartilage", is a piece of cartilage from which the mandibles (lower jaws) of vertebrates evolved.

Letognathus is important for rhizodont systematics because it retains a number of primitive features, such as ossified Meckel's cartilage, are not found in the genera Rhizodus and Strepsodus.

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.

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.

In humans, the cartilaginous bar of the mandibular arch is formed by what are known as Meckel's cartilages (right and left) also known as Meckelian cartilages; above this the incus and malleus are developed.

In pig embryos he discovered that the mandible ossifies on the side of Meckel's cartilage, while the posterior part of that cartilage is ossified and then detaches from the rest of the cartilage to enter the middle ear where it becomes the incus.
