 hyaline cartilage | provides sturdy support with some resilience or "give" most skeletal cartilages are composed of hyaline |
| elastic cartilage | much more flexible than hyaline cartilage and it tolerates repeated bending better. only the cartilages of the external ear and the epiglottis |
| fibrocartilage | consists of two rows of chondrocytes alternating with rows of thick collagen fibers. has great tensile strength and can withstand heavy compression. used to construct the intervertebral discs and the cartilages within the knee joint |
| compact bone | looks smooth and homogeneous |
| spongy bone | or cancellous bone, is composed of small trabeculae (bars) of bone and lots of open space |
| long bones | much longer than they are wide, consist of a shaft with heads at either end. composed predominantly of compact bone such. femur and phalanges |
| short bones | typically cube shaped and they contain more spongy bone than compact bone. the tarsals and carpals |
| flat bones | generally thin, with two waferlike layers of compact bone sandwiching a layer spongy bone between them |
| irregular bones | bones that do not fall into one of the preceding categories. the vertebral bones |
| sesamoid bones | are special types of short bones formed in tendons - the patellas |
| wormian or sutural bones | tiny bones between cranial bones. are not included in the bone count of 206 |
| ramus | armlike bar of bone |
| meatus | canal-like passageway |
| groove | furrow |
| foramen | round or oval opening through a bone |
| fissure | narrow, slitlike opening |
| fossa | shallow basinlike depression in a bone, often serving as an articular surface |
| tuberosity | large rounded projection; may be roughened |
| condyle | rounded articular projection |
| trochanter | very large, blunt, irregularly shaped process (femur) |
| tubercle | small rounded projection or process |
| epicondyle | raised area on or above a condyle |
| spine | sharp, slender, often pointed projection |
| crest | narrow ridge of bone; usually prominent |
| head | bony expansion carried on a narrow neck |
| diaphysis | shaft |
| endosteum | lining of the shaft |
| epiphysis | the end of the long bone |
| epiphyseal line | once the long bone has stopped growing, these areas are replaced with bone and appear as thin, barely discernible remnants |
| epiphyseal plate | a thin area of hyaline cartilage that provides for a longitudinal growth of the bone during youth |
