Skeletal System

2. Very tiny, flat, irregularly shaped bones located between the flat bones of the skull.
4. Over-stretches or tears to ligaments that connect at a joint.
6. These bones consist of ribs and the sternum or breastbone that protects many internal organs such as the heart and lungs.
9. Thigh bone in the upper leg. It is the longest bone in the body.
11. Also called osseous tissue. A hard, dense connective tissue that forms most of the adult skeleton.
14. The production of blood cells.
16. Kneecap.
17. The lifelong process of old or damaged bone being removed and replaced with new bone tissue.
18. This skeletal section forms the body’s central axis and includes the skull, vertebral column, and thoracic cage.
20. These bones consist of 24 vertebrae, the sacrum, and the coccyx or tailbone. Its primary job is to protect the spinal cord.

1. A smooth, elastic, connective tissue that protects the ends of bones at joints and serves as a structural component in many body parts.
3. These bones consist primarily of flat bones found in the skull that surround and protect the brain.
4. Joints with a cavity that generally provides a greater range of motion.
5. The bone is split or bent but does not entirely break.
7. Also known as “brittle bone disease”. A disease where the bones become thinner and more porous, which means the regular honeycomb-shaped holes and spaces in healthy bones become larger.
8. A structure where two or more bones or cartilage join together.
10. A protein that creates strong fibers found in the body’s various connective tissues.
12. Connective tissue that connects bone to bone and adds strength and support to a joint.
13. Connective tissue that connects bones to muscles.
15. Where the arms attach to the axial skeleton and include two clavicles or collarbones and two scapulas or shoulder bones.
16. Bones that form the fingers and toes.
19. Bones that form the wrist.
