Joints Flashcards
functional classification of joints
synarthrosis, amphiarthrosis, diarthrosis
synarthrosis
immovable joints
synarthrosis examples
sutures, synchondrosis, gomphosis
synchondrosis
epiphyseal plate
gomphosis
fibrous joint anchoring root of tooth in socket
amphiarthrosis
slightly movable joints
amphiarthrosis examples
syndesmosis, symphysis
syndesmosis
dense fibrous connective tissue located on the distal or proximal portion of long bones
syndesmosis examples
distal tibia and fibula, distal radius and ulna
symphysis
cartilaginous joint (fibrocartilage)
symphysis examples
pubic symphysis and intervertebral discs
diarthrosis
freely movable joint
diarthrosis example
synovial joints
synovial joints
have a space between the bones called a synovial join cavity that contains synovial fluid. also has articular cartilage
meniscus
shock absorber for knee at joint
bursae
small fluid filled sacs that reduce friction between moving parts of joints
structural classifications of joints
fibrous, cartilaginous, synovial
fibrous joints
no joint cavity, fibrous connective tissue holds bones together
fibrous join examples
sutures, tibia and fibula connection, gomphosis of teeth
cartilaginous joints
no joint cavity, cartilage connects bones together
synovial joints have
a joint cavity
ligaments provide
synovial joints extra support
synovial joint structure
synovial membrane surrounding synovial cavity, all encased in articular capsule
types of diarthrosis joints
planar, hinge, pivot, condyloid, saddle, ball+socket
planar joint
rub together
hinge joint
trochlea of humerus and trochlear notch of ulna at elbow
pivot joint
head of radius and radial notch of ulna
condyloid joint
(round rubbing) radius and scaphoid and lunate bones of carpus
saddle joint
(rocking) trapezium of carpus and metacarpal of thumb
ball and socket joint
head of femur and acetabulum of hip bone
knee joint bursae
suprapatellar, prepatellar, infrapatellar
knee joint tendon
quadriceps femoris, patellar ligament
