What is elastic cartilage?
Matrix like hyaline but addition of many elastic fibres and elastic lamellae. Found in external ear, epiglottis.
What is fibrocartilage?
abundant type 1 collagen fibres in addition to the matrix of material of hyaline cartilage. Contains chondrocytes as well as fibroblasts. Strongest type, no perichondrium. Found in pubic symphysis, IV discs, SC joint.
What are synovial joints?
