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
