- Raised area on or above a condyle.
- Spine
- Sharp, slender, often pointed projection/process.
- Process
- Prominence or projection.
- Head
- Bony expansion carried on a narrow neck.

- Smooth, nearly flat articular surface.
- Condyle
- Rounded, convex articular projection.

- Armlike "bar" of bone.
- Antrum
- Chamber within a bone.
- Sinus
- Space within a bone, filled with air and lined with mucous membrane.

- Axial Skeleton
- Bones that lie around the body's centre of gravity (head, neck, and trunk)
