  1. Skeletal System 4/9/12

  2. The Skeletal System • The function of the skeletal system is to give us support and to be able to move around. • Without the skeletal system, we would all be a blobs and just be a big bag like body.

  3. Role of Bones, ligaments, muscles, and tendons in movement • Bones are the key of movement and to go to different places. • Muscles contract and make the movement and momentum to perform different tasks. • Ligaments are fibrous bands or sheets of connective tissue linking two or more bones, cartilages, or structures together. So they hold everything together so you can move. • Tendons are structures in your body that connects a muscle to a bone.

  4. Hydrostatic Skeleton • This is a structure found in many cold-blooded organisms and soft-bodied animals that consists of a fluid-filled cavity, the coelom, surrounded by muscles. • The pressure of the fluid and action of the surrounding muscles are used to change an organism's shape and produce movement, such as burrowing or swimming.

  5. Exoskeleton • An exoskeleton are found in arthropods and many other species, the exoskeleton is made up of chitin. • The skeleton is on the outside of the body instead of on the inside.

  6. Endoskeleton • An internal supporting skeleton, from the mesoderm, that is a characteristic of vertebrates and certain invertebrates. • We have an endoskeleton.

  7. Osteoporosis • Osteoporosis is a disease that is the loss of of bone tissue. • In osteoporosis, the cancellous bone loses calcium, becomes thinner, and may disappear altogether.

  8. Scurvy • Scurvy is a disease caused by lack of vitamin C in a person’s diet. If a person does not get enough vitamin C, any wounds the person may have heals poorly. • This disease was more common on ships a long time ago.
