| A | B |
|---|
| Tuberosity (ligament & muscle attachment) | Large rounded projection; may be roughened |
| Crest (ligament & muscle attachment) | Narrow ridge of bone usually prominent |
| Trochanter (ligament & muscle attachment) | very large, blunt, irregularly shaped process. (the only examples are on the femur.) |
| Line (ligament & muscle attachment) | Narrow ridge of bone; less prominent than a crest |
| Tubercle (ligament & muscle attachment) | Small rounded projection or process |
| Epicondyle (ligament & muscle attachment) | Raised area on or above a condyle- next to the joint where muscles & ligaments attach |
| Spine (ligament & muscle attachment) | Sharp, slender, often pointed projection |
| Process (ligament & muscle attachment) | Prominence or projection |
| Head (projections that help to form joints) | Bony expansion carried on a narrow neck |
| Facet (projections that help to form joints) | Smooth, nearly flat articular surface |
| Condyle (projections that help to form joints) | Rounded articular projection |
| Ramus | Armlike bar of bone |
| Sinus | Space w/in a bone, filled with air & lined w/ mucous membrane |
| Meatus | Canal like passageway |
| Fossa | Shallow, basinlike depression in a bone, often serving as an articular surface |
| Groove | Furrow |
| Fissure | Narrow, slitlike opening |
| Foramen | Round or oval opening through a bone |
| Long Bones | Longer than they are wide, generally consisting of a shaft w/ heads at either end. Composed predominately of compact bone. |
| Short Bones | typically cube shaped, & they contain more spongy bone than compact bone |
| Flat Bones | Generally thin, w/ two waferlike layers of compact bone sandwiching a layer of spongy bone between them. |
| Sesamoid | Short bones formed in thendons (patellas) |
| Wormian or Sutural Bones | tiny bones between cranial bones |
