The Appendicular Skeleton
(Bones of the appendages or limbs)
• Bones have bumps, holes and ridges or bone markings.
• Bone Markings fall into two categories:
– Projections (processes) – serve as sites of muscle attachment or help
– Depressions (cavities, indentations or openings) – conduits for nerve
and blood vessels.
The following tables summarize the bone markings.
