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
