| Diaphysis | central shaft of long bone, surrounds marrow cavity |
| Marrow cavity | contains bone marrow |
| Epiphyses | ends of long bone, covered in articular cartilage, articulates with an adjacent bone at a joint |
| Compact (dense) bone | relatively solid, found in diaphysis of long bone |
| Spongy (cancellous) bone | resembles network of bony rods separated by spaces, found in epiphyses |
| Periosteum | covering of bone, isolates bone from surrounding tissue, provides circulatory and nerve supply routes, assists with repair and growth |
| Endosteum | lines marrow cavities and other inner surfaces, active during bone growth and repair |
| Process | any large prominence or extension, bump, projection |
| Ramus | an extension of a bone making an angle with the rest of the structure. |
| Spine | a pointed process |
| Condyle | a smooth, rounded articular process |
| Foramen | a rounded passageway for blood vessels or nerves |
| Canal/meatus | a passageway through the substance of the bone |
| Sinus | a chamber within a bone, normally filled with air |
| trochanter | very large rounded process for tendon attachment (greater and lesser on femur) |
| tuberosity | large, rough projection for tendon attachment |
| tubercle | small rounded projection (muscle attachment on bones |
| crest | a prominent ridge |
| linea | a line or low ridge |
| fossa | a shallow depression |
| head | an expanded articular end of an epiphysis |
| neck | narrow connection between the epiphysis and diaphysis |
| sulcus | a narrow groove |
| trochlea | a smooth, grooved articular surface shaped like a pully |
| facet | a small, flat articular surface for articulation with adjacent bones |
| fissure | an elongated cleft |
