fibrous joint
cartilaginous symphysis
formed by fibrocartilage and is typically classified as amphiarthrotic
cartilaginous synchondrosis
formed by hyaline cartilage and is typically classified as synarthrotic
fibrous syndesmosis
formed by longer bands of collagen fibers that those which form sutures and gomphoses and typically classified as amphiarthrotic
fibrous gomphosis
formed by short bands of collagen fibers and typically classified as synarthrotic, but some are amphiarthrotic
cartilaginous joints
formed when bones are articulated by cartilage
fibrous joints
formed when bones are connected by bands of collagen fibers
synovial ball and socket
formed when the spherical head of one bone articulates with the concave socket of another bone
diarthrosis (diarthrotic)
freely movable joints
description of movement: atlantoaxial
head rotation
synarthrosis (synarthrotic)
immovable joints
what do longer fibrous fibers do
increase the mobility of a joint
synovial hinge
joint is an articulation between a cylindrical suave and a concave surface
synovial plane
joint is characterized by flat articulating surfaces
synovial condylar
joint is formed by the articulation of two oval surfaces
synovial pivot
joint is usually formed by a rounded bone which is wrapped with a tough ligament
what are some accessory structures associated with synovial joints
ligaments and tendons
synovial joints
most complex, bones are separated by a joint cavity which is filled with synovial fluid
