| Functions of the Skeletal System: how does it make it MOVE? | Attachment point for muscles |
| Functions of the Skeletal System: what does it STORE? | Fat, calcium, and phosphorus |
| Functions of the Skeletal System: what occurs in BLOOD CELL FORMATION? | Hematopoiesis occurs in the marrow |
| Diaphysis | shaft of the bone |
| Epiphysis | ends of the bone (promixal and distal) |
| Medullary Cavity | hollow cavity within the bone |
| Compact Bone | dense bone; appears solid |
| Spongy Bone | bone with small cavitites; resembles a sponge |
| Yellow Bone Marrow | membrane that forms the inside of the bone (fat) |
| Red Bone Marrow | boundary that allows growth; seals as an adult |
| Articular Cartilage | smooth, slippery surface to reduce friction at joints |
| Axial Skeleton | Along the longitudial axis of the body |
| Appendicular Skeleton | The appendages of the axial skeleton |
| What is an example of a LONG BONE? | Femur |
| What is an example of a SHORT BONE? | Carpals |
| What is an example of a FLAT BONE? | Ilium |
| What is an example of a IRREGULAR? | Spine |
| What is the characterisic of FIBROUS JOINTS? | bone ends or parts united by collagenic fibers |
| What is the mobility of the FIBROUS JOINTS? | immobile, slightly mobile |
| What is some examples of a FIBROUS JOINT? | skull, between lower leg bones, teeth |
| What is the characteristic of CARTILAGINOUS JOINTS? | bone ends or parts united by cartilage |

| What are some types of SYNOVIAL JOINTS? | plane/gilding, hinge, pivot, ellipoidal, saddle, ball & socket |
| What is the mobility of SYNOVIAL JOINTS? | freely moveable (movements depend on design of joint) |
