How are joints classified by function?
by amount of movement allowed at the joint
These are immovable joints
synarthroses
slightly movable joints are called?
amphiarthroses
These joints are freely movable and ligaments hold it together with a wide range of motion
diarthroses
How are joints classified by structure?
by the materials that join them together
Synarthroses joined by fibrous tissue, no joint cavity present. What type of joint is this?
fibrous joints
These joints are connected by cartilage
cartilaginous joints
cartilaginous joints epiphyseal plates
Synchondrosis
Intervertebral disks of the spine and Pubic symphysis are examples of what type of cartilaginous joints
Symphyses
most moveable joints;
diarthroses, fluid-filled joint cavity
synovial joints
where 2 bones fuse so boundary disappears (e.g., frontal bones, epiphyseal lines of mature bones)
synostosis
joint where bones are connected by a ligament or an interosseous membrane
e.g., between tibia and fibula
syndesmosis
where teeth are bolted into bony sockets by periodontal ligament
gomphoses
joint between the pubic bones
pubic symphysis
synovial joints have what two components ?
articular cartilage, synovial cavity
synovial joint cavity is surrounded by a 2-layer capsule
articular capsule
synovial joint continuous with periosteum of articulating bones
outer fibrous capsule
membrane of loose connective tissue, covers all internal surfaces of synovial joint
inner synovial membrane
viscous fluid of hyaluronic acid
Synovial fluid
fibrocartilage pad between bones
meniscus
cushions the bones
fat pads
water balloons” in connective tissue, have synovial fluid
bursae
inflammation from repetitive motion
bursitis
pressure bursitis at base of big toe
bunion
