Skeleton vocabulary

I'm sure some of you were missing the post about the vocabulary:

  • Bone marrow Soft connective tissue found inside many bones; site of blood cell formation.

  • Cartilage Smooth covering found at the end of bones; made of tough collagen protein fibers; creates smooth surfaces for the easy movement of bones against each other.

  • Compact bone The dense, hard outer layer of a bone.

  • Joint Point at which two or more bones meet.

  • Ligaments Fibrous tissue that connects bones to other bones; made of tough collagen fibers.

  • Movable joint Most mobile type of joint; the most common type of joint in the body.

  • Skeletal system Body system that is made up of bones, cartilage, and ligaments.

  • Skeleton Sturdy scaffolding of bones and cartilage that is found inside vertebrates.

  • Spongy bone Lighter and less dense than compact bone; found toward the center of the bone.

  • Sprain A ligament injury; usually caused by the sudden overstretching of a joint which causes tearing.
