What's the difference between cartilage and perichondrium?
Cartilage
Definition:
(n.) A translucent, elastic tissue; gristle.
Example Sentences:
(1) The fibrous matrix and cartilage formed within the nonunion site transformed to osteoid and bone with increased vascularity.

(12) The buccal glands of adults of the Southern Hemisphere lamprey Geotria australis consist of a pair of small, bean-shaped, hollow sacs, embedded within the basilaris muscle in the region below the eyes and to either side of the piston cartilage.
(13) These observations suggest that the function of BMG is to evoke mesenchymal cell differentiation into prechondroblasts during the latent or migratory morphogenetic phase while the effect of the culture medium is to provide the bionutritional requirements for synthesis of hyaline cartilage matrix by chondrocytes during the patent phase of development.
(14) The cartilage of the concha is a valuable substitute of the bridge and the posterior wall of the external auditory conduct.
(15) the synovium has a) a direct, presumably enzymatic action on cartilage matrix and b) an indirect effect mediated through the chondrocytes.
(16) New insights into the biochemical and cell-biological alterations occurring in articular cartilage during the early phase of osteoarthrosis (OA) have been gained in the past decade by analysing experimentally induced osteoarthrosis in animals, mostly dogs and rabbits, while early phases of OA in humans so far have escaped diagnostic evaluation.
(17) The use of SDS-polyacrylamide gel electrophoresis of the cyanogen bromide derived peptides from fibrous cartilage collagens enabled to calculate type I to type II collagen ratio in this tissue.
(18) After transplantation chondrocytes from regenerated cartilage reconstructed cartilage in one out of ten transplants.
(19) Chemically isolated separate preparations of the non-aggregating protein-chondroitin-keratin sulphate (PCKS) fraction from the hyaline cartilage and hyaluronic acid (HUA) of the vitreous body and of the umbilicus were investigated by electron microscopy.
(20) Standard methods of glycosaminoglycan separation were used to confirm the presence of hyaluronic acid in sheep and rabbit articular cartilage.
Perichondrium
Definition:
(n.) The membrane of fibrous connective tissue which closely invests cartilage, except where covering articular surfaces.
Example Sentences:
(1) Fascia TM grafts atrophied in 35 of 43 ears (80%), and perichondrium atrophied in 8 of 20 ears (40%).
(2) Nerve fibers showing SP- and CGRP-LI were also observed close to the acini and ducts of the glands, in the blood vessel walls, close to the perichondrium of all the cartilages, and outside the cricothyroid and cricoarytenoid joints.
(3) Orthopedic new approaches to therapy of OA include removal of abnormal tissue to stimulate repair (e.g., burring, abrasion) and grafting (e.g., osteochondral grafts, perichondrium, periosteum) to the subchondral bone.
(4) The cartilaginous potential of the perichondrium has earlier been utilized to reconstruct articular cartilage in unloaded joints in adult rabbits.
(5) Treated embryos showed a delay in the longitudinal growth of the tibia, as well as in the growth of all structures enclosed by the perichondrium-periosteum.
(6) After perichondrium implantation, the following sequence in tracer distribution was demonstrated.
(7) The results support earlier morphological findings, indicating that perichondrium from rib cartilage has a better ability to regenerate than auricular perichondrium.
(8) In many species cartilage autografts survive and grow despite the absence of perichondrium and synovial membrane.
(9) Eight 21-day-old rabbits completed the study in which perichondrium was elevated from one cartilaginous surface of one ear and the nonoperated ear served as a control.
(10) Deep to the perichondrium, the chondrocytes are packed with intermediate filaments.
(11) The surrounding connective tissue and the perichondrium showed weak type I collagen expression, while the zones of desmal ossification like the clavicle gave a strong signal.
(12) The purpose of this study is to define and discuss this clinical entity and the use of cartilage-perichondrium tympanoplasty as a safe and predictable method of treatment, reducing destructive complications while maintaining ear function.
(13) Nasal cartilage wounds rapidly rounded off and the perichondrium reformed without evidence of callus formation.
(14) Tympano-cartilago-stapediopexy was performed in the other 95 cases by using tragal cartilage and perichondrium over the stapes.
(15) Tragal perichondrium is a widely used tissue seal in the oval window following stapes surgery.
(16) The lesion may then be enucleated or resected, and the defect, if any exists, closed with overlying mucosa and the flap of preserved perichondrium.
(17) An extensive alkaline phosphatase activity was demonstrated on the plasma membrane of fibroblasts and chondroblasts in the external perichondrium.
(18) The influence of perichondrium on healing was studied by comparing ulcers with and without perichondrium on 1) formation of total healing wound area (HWA, the newly formed connective and granulation tissues within the ulcer) over time and 2) the amount of collagen synthesized by the wound tissue at day 5.
(19) A xenograft of costal rabbit perichondrium was transplanted to an articular cartilage defect in a sheep knee.
