Cartilage
Types
Hyaline, elastic, fibro Give location, characteristics
Type Location CharacteristicsHyaline articular, larynx, trachea, bronchi,
costalType II Collagen, GAGs, chondronectin, bound water
Elastic auricles, ext. auditory tube, eustachian tube, epiglottis
like hyaline, but with elastic fibers
Fibro Intervertebral disks, pubic symphysis, TMJ
like dense irregular CT, Collagen type I&II, very little ground substance
