LO1: Skeletal System Components Bones, cartilages and ligaments Cartilage ­ forerunner for bone tissue, covers most joints in adults Elastic (epiglottis, outer ear) Hyaline (most abundant, growth plates) Less in adults, bc growth plates have solidified fibrous Ligaments ­ hold bones together at joints (articulations) Bone ­ mineralized CT, blood, marrow, cartilage, adipose, nervous/fibrous CT Rebuilt stronger (due to blood supply, mitosis, support) Skeletal Cartilages Hyaline—most abundant (frictionless, lots thin fibers) Articular: btwn where 2 bones meet NOT all articulations have articular cartilage Epiphyseal plate counts as an articulation
