| 3 skeletal systems | bones, cartilage, joints |
| Perichondrium | connective tissue surrounding cartilage |
| what is the most abundant cartilage? | hyaline |
| articular cartilage | covers ends of long bones |
| costal caertilage | connects to ribs and sternum |
| respiratory cartilage | makes up larynx; reinforces air passage |
| nasal cartilage | supports the nose |
| elastic cartilage | similar to hyaline, but contains elastin; found in external ear and epiglottis |
| Fibrocartilage | highly condensed with tensile strength; contains collagen fibers; found in menisci of the knee and in intervertebral discs |
| 5 functions of bones | support, protection, movement, storage, and blood cell formation |
| hematopoiesis | formation of blood |
| long bone | levers of the body; longer than they are wide (e.g. humerus) |
| short bone | cube shaped bones of the wrist and ankle |
| sesamoid bones | bones that form with tendons (patella) |
| flat bones | thin, flattened, and a bit curved, serve as protection (sternum, skull) |
| wormian bones | extra-ossification centers; sutural bones (skull) |
| irregular bones | bones with complicated shapes (vertebral and hip) |
