common bone features

Common Bone Features• Articular surfaces

– Joint surfaces (where bones come in contact with each other to form joints)

– Covered by articular (_____________) cartilage

– Consists of:• ____________- large, round (usually distal) articular surface

• ____________- spherical proximal end of a long bone at the articular surface

• ___________- flat articular surface

Common Bone Features: Condyle• Large, round (usually distal) articular surface.• Major condyles: distal end of humerus, distal end of

femur, occipital skull bone.

Common Bone Features: Head• Somewhat spherical articular surface on the proximal

end of a long bone.• Found on humerus, femur and rib.• Head is usually joined with rest of bone by a ________.

Common Bone Features: Facet• A flat articular surface.• Found in carpal and tarsal bones as well as in

vertebrae, radius and ulna.

Common Bone Features: Processes• Lumps, bumps, and projections on a bone.

– may (heads and condyles) or may not involve a joint– may be a site of tendon attachment– trochanter (femur), tubercle (humerus), crest (tibia), tuber

(ischium), olecranon (ulna), spine (scapula) wing (atlas)
