Chapter 3 The Skeletal System

Overview of Structures, Combining Forms, and Functions © 2009 Delmar, Cengage Learning

Bones Primary Function Related Combining Forms Act as the framework for the body Protect the internal organs Store the mineral calcium Related Combining Forms oss/e, oss/i oste/o, ost/o

Lateral View of Skull

Anterior View of Skull

Bone Marrow Primary Functions Related Combining Form Red bone marrow forms some blood cells. Yellow bone marrow stores fat. Related Combining Form myel/o (also means spinal cord)

Cartilage Primary Functions Related Combining Form Creates a smooth surface for motion within the joints. Protects the ends of the bones. Related Combining Form chondr/o

Joints Primary Function Related Combining Form Work with the muscles to make a variety of motions possible. Related Combining Form arthr/o

Examples of Synovial Joints

Synovial Joint

Ligaments Primary Function Related Combining Form Connect one bone to another. Related Combining Form ligament/o

Synovial Membrane Primary Functions Related Combining Forms Forms the lining of synovial joints. Secretes synovial fluid. Related Combining Forms synovi/o, synov/o

Synovial Fluid Primary Function Related Combining Forms Lubricant that makes smooth joint movements possible. Related Combining Forms synovi/o, synov/o

Bursa Primary Function Related Combining Form Cushions areas of joints that are subject to friction during movement. Related Combining Form burs/o
