Answer 1

synarthrosis - immobile
amphiarthrosis - some limited movement (cartilage)
diarthrosis - mobile, synovial joints

Question 2

4 types of synarthrosis

Answer 2

articulationes fibrosae - ex skull sutures, tooth in socket
cartilagenous joint - symphysis pelvis(CA)
synostosis - fusion of bones
synsarcosis - joint only supported by muscle

Question 3

Answer 3

plana
serrata
squamosa
foilata

Question 4

Answer 4

peg-and-socket joint ex teeth

Question 5

amphiarthrosis ex

Answer 5

cartelagenous joint: vertebrae; intervertebral disc

Question 6

capsula articularis

Answer 6

diarthrosis: inner stratum synoviale and outer stratum fibrosum

Question 7

discus and meniscus for

Answer 7

incongruent joints

Question 8

mobile joint classification regarding number

Answer 8

simplex: humeri
duplex: femorotib
composita: cubiti

Question 9

mobile joint classification regarding axis

Answer 9

monoaxis: flex or ext
biaxial: flex/ext + adductio/abduction
multiaxial: flex/ext + adductio/abduction + rotation

all three together = circumduction (making circles)

Question 10

mobile joint classification regarding movement

Answer 10

limited
partly limited
unlimited, ex temporomandibular joint

limited by skin, tendons, ligaments, muscle, cartilago, capsule size etc

Question 11

name 5 examples for monoaxial movements

Answer 11

hinge, cubiti
cochlear, tarsocruralis
plana,  art. proc. articulare vertebrale
sledge,  femoropat
pivot atlantoaxialis (dens), prox radioulnar

Question 12

name 3 examples for biaxial

Answer 12

saddle: interphalangeal joints
condylaris: femorotib, temporomand
ellipsoidea, ex atlantooccipitalis

Question 13

multiaxial ex

Answer 13

spheroidea, most freely movable joint|
