6.2 Cartilage

interstitial growth

chondrocytes in the center of the tissue divide and add more matrix in-between the existing cells

collagen and proteoglycan

the matrix contains ___ and ___

hyaline cartilage, fibrocartilage, elastic cartilage

three types of cartilage

-blast

"seed" or "bud"

perichondrium

- protective connective tissue sheath that covers most cartilage - double-layered outer layer of dense irregular connective tissue containing fibroblasts

lacuna

a rounded cell that occupies a space within the matrix

appositional growth

chondroblasts in the perichondrium add new cartilage to the outside edge of the existing cartilage

chondrocyte

by the time the matrix has surrounded a chondroblast, the cell has differentiated into a ___

hyaline cartilage

cartilage mostly associated with bone

articular cartilage

hyaline cartilage that covers the ends of bones where they come together to form joints, has no perichondrium, blood vessels, or nerves

proteoglycan

makes cartilage resilient by trapping water

-blast to -cyte

once the immature cell has grown and differentiated into its mature form (suffix change)

hyalin cartilage chondroblast

produces a matrix surrounding themselves

collagen

provides cartilage strength

appositional growth and interstitial growth

two types of cartilage growth
