How many? Born w/300 bones By adulthood, most people have bones due to fusion Bone number varies primarily in supernumerary ribs, lumbar vertebrae and sesamoid bones

Why so different? Greatest number of bones are in wrist (54), 2x that of foot (26) and almost 4x as many as face

Why So Different?

Divisions of the Skeleton Axial Skeleton –All the bones that make up the longitudinal axis of the body (skull, ribs & sternum, and vertebral column) Appendicular Skeleton –The bones of the limbs, phalanges, and girdles (pectoral and pelvis) –Connective Tissues (Joints, cartilages, and ligaments)

Joints With the exception of the hyoid bone, all bones connect with at least one other bone at a point called the articulation or joint There are three types of joints: –(1) Fibrous Joints –(2)Cartilaginous Joints –(3) Synovial Joints

Bursa Bursae are flattened fibrous sacs lined with synovial membrane and containing a thin layer of synovial fluid Common where ligaments, muscles, skin, tendons, or bones rub together Bursitis is inflammation of the bursa
