Bio 2 Chapter 8 Articulations

Front 1

what are the two was to classify a joint

Back 1

degree of motion and characteristics

Front 2

what are the three types of joint based on degree of motion

Back 2

non-movable, slightly movable, freely movable

Front 3

ex: suture

Back 3

fibrous joints

Front 4

is united by *word* connective tissue, has no joint cavity, and moves little or none?

Back 4

fibrous joint

Front 5

slightly movable and unite two bones by means of fibrocartilage

Back 5

cartilaginous joint

Front 6

ex: symphysis pubis, invertebral disks

Back 6

cartilaginous joints

Front 7

allow considerable movement, most complex, most common, and contain a certain type of fluid

Back 7

synovial joints

Front 8

structures of synovial joints

Back 8

articular cartilage, joint cavity, fibrous capsule, synovial membrane/fluid

accessory: bursae, ligaments and tendons, meniscus

Front 9

occurring around several axes

Back 9

multiaxial

Front 10

occurring around two axes at right anglese to each other

Back 10

biaxial

Front 11

joint cavity contains

Back 11

synovial fluid

Front 12

pockets of synovial fluid that extend from the joint; found in areas of friction

Back 12

bursae

Front 13

fibrocartilaginious pads in the knee

Back 13

meniscus

Front 14

some rotation possible but limited by surrounding structures; monoaxial

Back 14

plane/ gliding joints

Back 18

hinge joint

Front 19

ex: elbow, knee

Back 19

hinge joints

Front 20

cylindrical bony process rotating within a circle of bone and ligament; monoaxial

Back 20

pivot joints

Front 21

multiaxial joints

Back 21

ball and socket

Front 22

ex: shoulder and hip joints

Back 22

ball and socket

Front 23

two main types of movement

Back 23

angular and circular

Front 24

bending parts at a joint

flexion

Front 25

straightening parts at a joint

Back 25

extension

Front 26

standing on toes

turning of a structure on its long axis

Back 30

rotation

Front 31

palm faces posteriorly (down)

Back 31

pronation

Front 32

palm faces anteriorly (up)

Back 32

supination

Front 33

combination of flexion, extension, abduction, adduction; appendage describes a cone; circular path

circumduction

Front 34

unique to only one or two joints

Back 34

special movement

Front 35

moves a structure superior (up)

Back 35

elevation

Front 36

moves a structure inferior (down)

Back 36

depression

Front 37

gliding motion forward (anteriorly)

Back 37

protraction

Front 38

moves structure back to anatomic position or even further posteriorly

Back 38

retraction

Front 39

moving mandible to the right or left of midline

Back 39

lateral

Front 40

return the mandible to the midline

Back 40
