Skeletal System

By Anikait 6th period

  • Ligaments are flexible but strong strand of connective tissue that allow movement in your body but some prevent to much movement. They are normally found at ends of the bone
  • Cartilage is strong flexible connective tissue that allows bones to move smoothly across each other. Cartilage does not contain any blood vessels at all.
  • Minerals are deposited from cells called osteoblasts. Minerals make bones strong and hard
  • Connective tissue in bone is mostly made up of collagen. Collagen in bones make them flexible to withstand bumps and knocks
  • Marrow is a soft tissue found in bones. There are two types of marrow red marrow is the site of platelet and red and white blood cell production. Yellow marrow is found in the middle of large bones like the femur and store fat

  • The ulna is one of the two long bones in the forearm
  • The radius is a long bone prism shaped and slightly curved longitudinally
  • Each vertebrate is a structure composed of bone and hyaline cartilage which varies according to the area of back bone they provided support for the body
