[Intrinsic regulation of the condylar cartilage growth rate (author's transl)]. 1980

J Stutzmann, and A Petrovic

The experimental results reported above, strongly suggest the existence of an intrinsic regulatory mechanism of the condylar cartilage growth rate. The cell density as such cannot account, at least not completely, for the findings. In other words, there must be a "negative feed-back signal" originating from the proximal part of the chondroblastic zone and exerting a restraining effect on the prechondroblastic multiplication rate. The concept of an intrinsic regulation of the condylar cartilage growth rate can help to explain the effects of some orthopaedic or orthodontic appliances as well as of a hormone, thyroxine. The earlier commencement of chondroblastic hypertrophy and the subsequent decrease in the prechondroblast restraining signal appear to be an important intermediary step in the growth-stimulating effect of the mandibular postural hyperpropulsor. The acceleration of the chondroblastic maturation rate is, in a similar way, an intermediary step for the growth-rate stimulating effect of thyroxine.

D008938 Mitosis A type of CELL NUCLEUS division by means of which the two daughter nuclei normally receive identical complements of the number of CHROMOSOMES of the somatic cells of the species. M Phase, Mitotic,Mitotic M Phase,M Phases, Mitotic,Mitoses,Mitotic M Phases,Phase, Mitotic M,Phases, Mitotic M
D011626 Pterygoid Muscles Two of the masticatory muscles: the internal, or medial, pterygoid muscle and external, or lateral, pterygoid muscle. Action of the former is closing the jaws and that of the latter is opening the jaws, protruding the mandible, and moving the mandible from side to side. Muscle, Pterygoid,Muscles, Pterygoid,Pterygoid Muscle
D002358 Cartilage, Articular A protective layer of firm, flexible cartilage over the articulating ends of bones. It provides a smooth surface for joint movement, protecting the ends of long bones from wear at points of contact. Articular Cartilage,Articular Cartilages,Cartilages, Articular
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D013006 Growth Hormone A polypeptide that is secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Growth hormone, also known as somatotropin, stimulates mitosis, cell differentiation and cell growth. Species-specific growth hormones have been synthesized.

D013974 Thyroxine The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in the THYROGLOBULIN. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.
