fibrous joints
bones joined by connective tissue
no joint cavity
cartilaginous joints
bones joined by cartilage
no joint cavity
synovial joints
joint cavity separates articulating bones
synarthrotic joints
immovable
amphiarthrotic joints
slight movement allowed
diarthrotic joints
freely moveable
sutures
fibrous joint
articulations between the bones of the cranium
syndesmoses
fibrous joint
bones connected by a cord or sheet of dense connective tissue
ligament
founds in syndesmoses (types of fibrous joints)
cords of dense connective tissue
interosseous membrane
found in syndesmoses (types of fibrous joints)
sheets of dense connective tissue
gomphoses
teeth to bony socket
synchondroses
cartilaginous joints
bones connected by hyaline cartilage
ex.) sternocostal joint of rib 1
symphyses
cartilaginous joints
bones connected by fibrocartilage
ex.) intervetebral joints
articular cartilage
found in synovial joints
consists of hyaline cartilage covering of bone
joint cavity
found in synovial joints
filled with synovial fluid
allows or easy and smooth movement
articular capsule
found in synovial joints
forms outer walls of joint cavities
reinforcing ligaments
found in synovial joints
provide support to joints
nonaxial movement
movement of synovial joint
slipping movement only
uniaxial movement
movement of synovial joint
movement in only one plane
ex.) elbow
biaxial movement
movement of synovial joint
movement in two planes
ex.) knuckle
multiaxial movement
movement of synovial joint
movement in three planes
ex.) shoulder
gliding movements
found in synovial joints
consist of flat surfaces sliding over each other
ex.) carpals
angular movements
found in synovial joints
lead to a change in the angle between two bones
ex.) elbow
flexion
an angular synovial movement
decreases the angle between two bones
extension
an angular synovial movement
increases the angle between two bones
abduction
an angular synovial movement
moves away from the body's midline
adduction
an angular synovial movement
moves toward the body's midline
circumduction
an angular synovial movement
movement is cone-shaped
rotation
consists of of movement around a long axis
ex.) atlas and axis
supination
a special synovial movement
consists of rotation of radius around the ulna
palm up
pronation
a special synovial movement
consists of rotation of radius around the ulna
palm down
dorsiflexion
a special synovial movement
toes up
plantar flexion
a special synovial movement
toes down
inversion
a special synovial movement
foots turns medially
eversion
a special synovial movement
foot turns laterally
protraction
a special synovial movement
consists of movement into anterior space
ex.) underbite
retraction
a special synovial movement
consists of movement into posterior space
ex.) overbite
elevation
a special synovial movement
upward movements
depression
a special synovial movement
downward movements
opposition
a special synovial movement
the thumb
plane joint
a type of synovial joint
consist of two flat surfaces
motion is nonaxial, gliding
ex.) intercarpal joints
hinge joint
a type of synovial joint
uniaxial movement, flexion and extension
ex.) elbow, knee, finger joints
pivot joints
a type of synovial joint
round part fits into a ring
joint restricts movement to rotation only
uniaxial, rotational
ex.) radioulnar joint
condyloid joints
a type of synovial joint
concave and convex oval surfaces that fit together
motion is biaxial, all angular motions
ex.) knuckle joints
saddle joints
a type of synovial joint
consists of two saddle shaped surfaces
motion is biaxial, all angular motions
ex.) carpometacarpal 1
ball-and-socket joints
a type of synovial joint
round end fits into concave surface
motion is multiaxial, universal movement
should and hip joints
