1. Practice Identifying Bone Markings: Use in conjuction with your bone markings to know worksheet

2. Bone markings:
Every bone (or matching pair of bones) in the body looks different from every other bone (or matching pair) because of bone markings.
There are three basic types of bone markings:
Processes that are sites of muscle and ligament attachment.
Processes that help to form joints.
Depressions, cavities, and openings that allow blood vessels and nerves to pass through a bone.
Generally, a bone process is an extension from the main body of a bone that serves as a site of muscle attachment or helps form a joint.

3. Tuberosity: A large rounded projection that may be roughened.
Here are the common processes that function as sites of muscle and ligament attachment:
Tuberosity: A large rounded projection that may be roughened.
Crest: Narrow, usually prominent, ridge of bone.
Condyle: Rounded articular projection.
Epicondyle: Raised area on or above a condyle.

4. Spine: Sharp, slender, often pointed process.
Tubercle: Small rounded process.
Trochanter: Very large, blunt, irregularly shaped process.
Line: Narrow ridge of bone that is less prominent than a crest.
Ramus: Arm-like bar of a bone.

5. Here are the common processes that function to help form joints:
Head: Bony expansion carried on a narrow neck.
Facet: Smooth, nearly flat articular surface.
Condyle: Rounded articular projection.
Fossa: Shallow, basinlike depression in a bone, often serving as an articular surface.

6. Here are the common depressions and openings that allow blood vessels and nerves to pass through bones:
Meatus: Canal-like passageway.
Sinus: Cavity within a bone, filled with air and lined with mucous membrane.
Groove: Furrow.
Fissure: Narrow, slit-like opening.
Foramen: Round or oval opening through a bone.
