Document Summary
Composed primarily of water spring back into original shape after being stretched. Surrounded by perichondrium layer of dense irregular connective tissue. Acts like a girdle: resist outward expansion when cartilage is compressed. Contains blood vessels: provides nutrients for cartilage. Only fiber types in matrix: collagen fibers. Articular cartilages: cover ends of most bones at movable joints. Respiratory cartilages: form skeleton of larynx, reinforce other respiratory passageways. More able to stand up to repeated bending. Appositional growth cartilage-forming cells in perichondrium secrete new matrix against external face of existing cartilage tissue. Interstitial growth lacunae-bound chondrocytes divide and secrete new matrix expands the cartilage from within. Includes bones of: skull, vertebral column, rib cage. Function: protect body parts, carry body parts, support body parts. Includes bones of: upper limbs, lower limbs, girdles shoulder bones & hip bones. Function: help us move from place to place, manipulate environment. Bones have unique sizes/shapes fulfill particular need.
