| Angle | A corner |
| Body | The main portion of the bone |
| Border | Edge of bone |
| Condyle | Rounded bump; usually fits into a fossa on another bone to form a joint |
| Crest | Moderately raised ridge; generally a site for muscle attachment |
| Epicondyle | Bump near a condyle; often gives the appearance of a “bump on a bump”; for muscle attachment |
| Facet | Flat surface that forms a joint with another facet or flat bone |
| Fissure | Long, cracklike hole for blood vessels and nerves |
| Foramen | Round hole for vessels and nerves (pl., foramina) |
| Fossa | Depression; often receives an articulating bone (pl., fossae) |
| Head | Distinct epiphysis on a long bone, separated from the shaft by a narrowed portion (or neck) |
| Line | Similar to a crest but not raised as much (is often rather faint) |
| Margin | Edge of a flat bone or flat portion of the edge of a flat area |
| Meatus | Tubelike opening or channel (pl., meatus or meatuses) |
| Neck | A narrowed portion, usually at the base of a head |
| Notch | A V-like depression in the margin or edge of a flat area |
| Process | A raised area or projection |
| Ramus | Curved portion of a bone, like a ram’s horn (pl., rami) |
| Sinus | Cavity within a bone |
| Spine | Similar to a crest but raised more; a sharp, pointed process; for muscle attachment |
| Sulcus | Groove or elongated depression (pl., sulci) |
| Trochanter | Large bump for muscle attachment (larger than a tubercle or tuberosity) |
| Tuberosity | Oblong, raised bump, usually for muscle attachment; also called a tuber; a small tuberosity is called a tubercle |
