chapter 9 review Flashcards
arthrology
study of joints
bones articulate at a
joint
3 classes of joints
synovial joint cartilaginous joint, and fibrous joint
joints can be descibed by their functional classes
synarthroses, amphiarthroses, and diarthroses
synarthroses
immobile joints. can be cartiliginous or fibrous
amphiarthroses
sligjhtly mobile joint. can be cartiliginous or fibrous.
diathroses
freely mobile joint. all synovial joints
their is a _______ relaitionship between mobility and stability
inverse
three types of fibrous joints
gomphoses, sutures, syndesmoses
fibrous joints and cartiliginous joints are _____ CT
dense regular
gomphoses is like a
peg in a socket
how is gomphoses is used in teeth
tooth held in place. by fibrous periodontal membranes. synarthroses
sutures found between
flat skull bones
sutures become ossified _____ in adults
synostoses
when an adult sutures form they are
synarthrotic
syndesmoses
bound by interosseous membrane, broad ligamentous sheet
syndesmoses found between
ulna and ulna, tibia and fibula
syndesmoses is
anthyarthroses
cartilaginous joints made of either
hyaline cartilage or fibrocartilage between bones
cartilaginous joints lack
joint cavity
cartilaginous joints are ______ or _____ mobile
immobile;slightly mobile
2 types of cartilaginous joints
synchondroses, and symphases
synchondroses
hyaline cartilage base, immobile (synarthrotic)
symphyses found in
pubic bone, vertebrae
fibrocartilage absorbs
shock, impact
symphyses made of
fibrocartilage
symphyses is
amphiarthrotic
synovial joints
freely movable (diathrotic)
most joints in the body are
synovial
synovial joints have a double-layered ____ _____
articular capsule
articular capsule is composed of
outer fibrous layer, inner synovial membrane
fibrous outer layer
ligaments
synovial inner membrane
synovial fluid
bones that have synovial joints have articular cartilage called
hyaline cartilage
joint cavity
space between articulating bones
joint cavity is lined by synovial membrane and secretes
synovial fluid
functions of joint cavity
lubricates articular caritlage
nourishes chondrocytes
acts as a shock absorber
bursae can be found in synovial joint
saclike structure contains synovial fluid
bursae help
alleviate friction
