the appendicular skeleton
the skeletal system serves many important functions; it provides the shape and form for the body, support and protection, allows bodily movement, produces blood for the body, and stores minerals. the number of bones in the human skeletal system is a controversial topic. humans are born with over 300 bones; however, many bones fuse together between birth and maturity. as a result, an average adult skeleton consists of 206 bones. the number of bones varies according to the method used to derive the count. while some consider certain structures to be a single bone with multiple parts, others may see it as a single part with multiple bones. there are five general classifications of bones. these are long bones, short bones, flat bones, irregular bones, and sesamoid bones. the human skeleton is composed of both fused and individual bones supported by ligaments, tendons, muscles and cartilage. it is a complex structure with two distinct divisions; the axial skeleton, which includes the vertebral column, and the appendicular skeleton.

in recent years, there have been several studies conducted on the catacombs of marcellinus and peter analyzing how the conditions within the catacombs effect the preservation of the skeletons. the overall agreed conclusion is that the thermal history within catacombs are highly favorable for bone preservation, even more so than that of skeletons exposed to open-air environments. bones located within larger catacomb chambers have been found to be significantly better preserved than bones located within the catacomb's smaller chambers. the hypothesis that many pathologists are working with is that bones located in close proximity to the catacomb walls are subject to some environmental conditions, specifically runoff and increased humidity; bones discovered near the center of the chambers are not subject to such conditions. this explains why bones located within smaller chambers are not in as good a condition because nearly every skeleton would be located close to the walls of the chamber. bones found in smaller chambers of the catacombs are also affected by diagenesis (the conversion of sediment to sedimentary rock that results in a chemical or physical change) due to the confined space.
