Key Questions

  • Answer:

    Although they might seem like opposites, endo and exo skeletons are actually more similar than you think.


    Endo and exo skeletons are both skeletal structures that have a similar purpose: to 1) support the organism that it’s in 2) provide protection to important organs or body parts and 3) give the organism structure so it can preform the tasks it needs to survive.

    Unfortunately, Both of these skeletons can also break but they both can regenerate through shedding or cell mitosis.

    Both of them are also hard, tough, and durable although they are made of different fibers and nutrients.

  • It is said that without bones we would be shapeless blobs that could not move.

    Bones give shape to the body, protection to organs and, with muscles, act as levels to help the body move.

  • All systems have several parts called organs. In the case of the skeletal system this includes bones, cartilage (different kinds), tendons and ligaments.

    Our skeletal system helps us move by using muscles and protects various organs like the brain, lungs and heart.

    The bones also store some fat, produce blood cells and stores some minerals like calcium.

    Holding the bones together are ligaments.


    Tendons help attach muscles to bones.


    Various cartilage types are also important.

    A synchrondrosis joint has bands of hyaline cartilage which unite bones and an epiphyseal plate.

    This is found for example, between the manubrium and first rib.

    Some fibrocartilage can be found between bones.
    For example, the pubis symphysis and the joint between bodies of vertebrae.
