1

function-synarthrosis

no movement

2

function- amphiarthrosis

slight movement

3

function- diarthrosis

free movement

4

joint structure

bony, fibrous, cartiligenous, synovial

5

suture

synarthrotic joint interlocked by dense fibrous connective tissue *skull

6

gomphosis

synarthrotic fibrous connection that binds teeth to sockets

7

synchondrosis

synarthrotic rigid cartiliginous bridge between 2 bones
*epiphyseal cartilage of long bones and between vertebrosternal ribs and sternum

8

synostosis

synarthrotic immovable fused bones
*epiphyseal lines

9

syndesmosis

amphiarthrotic bones connected by ligaments
*distal art. b/t tibia and fibula

10

symphysis

amphiarthrotic bones seperated by fibrocartilage
*art. b/t 2 pubic bones

11

synovial

diarthrosis- moveable joints w/n articular capsules and lined w synovial membrane

12

articular cartilage

pad art. surfaces to prevent bones touching

13

synovial fluid function

lubrication, nutrient dist., shock absorption

14

sprain

ligament with torn collagen fibers

15

bursae

pouch of synovial fluid that cushions where tendons or ligament rub

16

dislocation

luxation
*subluxation- partial dislocation

17

dynamic motion types-3

linear (glide), angular, rotation

18

3 planes of dynamic motion

monaxial, biaxial, triaxial

19

gliding

2 surfaces slide past each other
*carpal and tarsal bones

20

flexion

angular movement in anterior-posterior plane that Reduces angle

21

extension

angular movement that increases angle

22

hyperextension

past anatomical position

23

abduction

moves away from long axis

24

adduction

moves toward long axis

25

circumduction

circular motion w/out rotation

26

pronation

rotates forearm- radius over ulna

27

supination

forearm in anatomical position

28

inversion

sole of foot medially

29

eversion

twist sole of foot laterally

30

dorsiflexion

lift toes
