Term | Definition |
---|---|
ARTICULATION | (joint) a point of contact between bones |
STRUCTURAL CLASSIFICATION | joints are named according to the type of connective tissue that joins the bones together. or by the presence of a fluid-filled joint capsule |
FUNCTIONAL CLASSIFICATION | joints are divided into three classes according to the degree of movement they permit |
FIBROUS JOINTS (SYNARTHROSES) | The articulating surfaces of bones that form fibrous joints fit closely together. syndesmoses, sutures, and gomphoses |
CARTILAGINOUS JOINTS (AMPHIARTHROSES) | The bones that articulate to form cartilaginous joints are joined together by either hyaline cartilage or fibrocartilage. synchondroses and symphyses |
SYNDESMOSES | Fibrous bands (ligaments) connect articulating bones |
SUTURES | Teethlike projections of articulating bones interlock with a thin layer of fibrous tissue connecting them |
GOMPHOSES | Fibrous tissue connects the roots of the teeth to the alveolar processes |
SYNCHONDROSES | Hyaline cartilage connects articulating bones |
SYMPHYSES | Fibrocartilage between articulating bones |
SYNOVIAL JOINTS (DIARTHROSES) | freely movable joints. They are not only the body’s most mobile but also its most numerous and anatomically most complex joints. |
UNIAXIAL JOINTS | Synovial joints that permit movement around only one axis and in only one plane. hinge and pivot joints |
BIAXIAL JOINTS | Diarthroses that permit movement around two perpendicular axes in two perpendicular planes. saddle and condyloid joints |
MULTIAXIAL JOINTS | Joints that permit movement around three or more axes and in three or more planes. Ball and socket, and gliding joints |
