Document Summary

The skeletal system ch 6 a overview of the skeletal system. The skeletal system is a dynamic organ system with tissues that grow & change throughout life. Cartilage is a supporting connective tissue tissue characteristics. Weaker than bone, but more flexible & resilient. Nutrient diffusion types of cartilage: hyaline cartilage. Covers the ends of long bones - articular cartilage. Costal cartilage - attaches ribs to sternum: fibrocartilage. Menisci - rings in between leg bones. Hold weight of upper body: elastic cartilage. Upon stretch returns to normal general functions of cartilage: supports soft tissue. Ex: airways in respiratory system, auricle of ear: gliding surface at articulations (joints) Smooth surfaces where bones meet: precursor model for bones growth. Beginning in embryo, cartilage grows & is replaced by bone growth patterns of cartilage. 2 types of growth: interstitial growth: growth from within the cartilage, appositional growth: growth from outside of cartilage bone. Bone is also a supporting connective tissue tissue characteristics.
