congrats on reading the definition of trabeculae. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. Trabeculae are found predominantly in spongy (cancellous) bone.
  2. They are oriented along lines of stress to provide maximum strength with minimal mass.
  3. Trabeculae contain red or yellow bone marrow in their spaces.
  4. The structure of trabeculae helps in reducing the weight of bones while maintaining strength.
  5. Trabecular bone undergoes constant remodeling through the actions of osteoblasts and osteoclasts.
