Infographic: Making Skeletons Seem Less Scary


Tuesday, October 27th, 2015

We all know skeletons are synonymous with Halloween, but there’s no reason to be afraid! The skeletal system does so much more than just keeping your body upright — it even helps to make blood cells!

Functions of the Skeletal System

Made up of 206 bones, the skeletal system’s functions include:

  • Blood cell production
  • Support
  • Movement
  • Protection
  • Ion storage
  • Endocrine regulation

Bone Composition

Do you know what makes up a bone in your body? Working from the outside in, here is a breakdown of your bone composition:

  1. Periosteum – Outer surface, thin membrane containing nerves and blood vessels
  2. Compact bone – smooth and hard, under the periosteum
  3. Cancellous bone – inside compact bone, resembles a sponge
  4. Bone marrow – inside compact bone, makes blood cells, resembles a thick jelly
