2. Bone Projections Process: raised area Olecranon process (ulna)
Coronoid process (ulna)
Styloid process (radius)

3. Bone Projections Tuberosity: large rounded or roughened projection
Deltoid tuberosity (humerus)
Radial tuberosity (radius)
Tibial tuberosity (tibia)

4. Bone Projections
Crest: Narrow ridge of bone
Anterior crest of tibia

5. Bone Projections Trochanter: very large, blunt projection
Greater and lesser trochanter of the femur

6. Bone Projections Line Ex: temporal line on parietal bone
A long, thin projection, often with a rough surface
Ex: temporal line on parietal bone

7. Bone Projections Tubercle: Small rounded projection
Greater and lesser tubercle of the humerus

8. Bone Projections Epicondyle Ex: distal end of femur
Bump near a condyle – “bump on a bump”
For muscle attachment
Ex: distal end of femur

9. Bone Projections Spine Ex: Spinous process of vertebrae
Raised higher than a crest
A sharp, pointed, slender projection
Attaches connective tissues
Ex: Spinous process of vertebrae
