chapter 9 study guide joints Flashcards
joint
any point where 2 bones meet
joint names
after bones or articular surfaces involved
joint functions
movement
flex bones
skeletal mobility
hold the skeleton together
classes of joints
bony joints
fibrous jjoints
cartilages joints
synovial joints
bony (synostoses) joints
original joint becomes ossified and bones become in effect one bone
fibrous (synarthroses) joints
joints held together by collagenous fibers
sutures
gomphoses
syndesmoses
sutures
serrate: interwoven very strong
lap: over lay each other
plane: butt up against each other
bones of the skull
gomphoses
hold teeth in socket
syndesmoses
long bones joined along shaft by intercrosseous membrane
(tibia/fibula)
solid joints
skull bones
serrate suture
major bones of skull
lap suture
minor bones of skull
sphenoid to temporal
plane suture
internal kull bones
bones of the maxilla
cartilaginous joints
synchondroses
symphyses
synchondroses joint
bones bound by cartilage
epiphyseal plate
symphyses joint
bones joined by fibrous cartilage
pubic symphysis
anatomy of synovial joint
joined by joint cavity
contains synovial fluid
ends of bone coverd in articular cartilage (hyaline)
enclosed in joint capsule
some contain an articular disc or discs (knee)
accessory structures of synovial joints
tendons (muscle to bone)
ligaments (bone to bone)
bursae
synovial joint categories
ball and socket
condylar
saddle
plane
hinge
pivot
ball and socket joint
hip
shoulder
condylar joint
metacarpophalangeal joint
saddle joint
trapezoimetacarpal joint proximal to thumb
plane joint
between carpal bones
hinge joint
