Answer 2

anteriorly

Question 3

hook of hammate can only be seen

Answer 3

anteriorly

Question 4

radiocarpal joint classification

Answer 4

synovial biaxial ellipsoid

Question 5

radiocarpal joint articular surfaces

Answer 5

distal end of radius
distal radioulnar joint articular disc
proximal row of carpals (not pisiform)

Question 6

radiocarpal joint- triangluar fibrocartliage complex

Answer 6

complex of ligaments and catliage
- distal radioulnar joint articular disc
- ligaments
functions:
- stabilise distal radioulnar joint
- transmitt and distrubute load form carpals to ulna
- helps to facilitate complex wrist movment

Question 7

palmer radiocarpal ligament where and funtion

Answer 7

from radius to carpal bones anteriorly

limits extension of the hand
ensures that the hand moves with the forearm during pronation and supernation

Question 8

dorsal radiocarpal ligament where and funtion

Answer 8

from radius to carpal bones on posteior side of hand

funtion
-ensures that the hand moves with the forearm during pronation and supernation

Question 9

radial collateral ligament where and funtion

Answer 9

from styloid process of radius to scaphoid and trapezium
funtion
- limit adduction of the hand

Question 10

ulnar collateral ligament where and funtion

Answer 10

from styloid process of ulnar to triqueetrum and pisiform
funtion
- limits abduction of the hand

Question 11

midcarpal joint classification

Answer 11

synovial compound joint

Question 12

midcarpal joint articular surfaces

Answer 12

proximal row of carpals
disatal row of carpals

Question 13

palmer ntercarpal ligaments

Answer 13

converges onto capitatae
funtion= limit extension of the hand

Question 14

dosal intercarpal ligament

Answer 14

limits flexion of the hand

Question 15

major contributions to movement by joints

Answer 15

flexion: midcarpal
extension: radiocarpal
abduction: radiocarpal
adduction: midcarpal

Question 16

intercarpal joints classification

Answer 16

synovial multiaxial plane
allow small gliding movments

Question 17

scapholunate ligament

Answer 17

function is to prevent the schapoid and the lunate bone from dislocating

Question 18

carpometacarpal joint of the thumb classification

Answer 18

synoival biaxial saddle

does flexion, extension ABD ADD circumduction and opposition. these occur in oposite planes and opposite axis

Question 19

carpometacarpal joint of the thumb articular surfacd

Answer 19

trapezium & base of 1st metatrsal

Question 20

carpometacarpal joint of the digits 2-5 classification

Answer 20

synovial, multiaxial, plane

Question 21

palmer carpometacarpal ligament

Answer 21

from distal row of carpal bones to bases of metacarpals 2-5 on anterior side

Question 22

dorsal carpometacarpal ligament

Answer 22

from distal row of carpal bones to bases of metacarpals 2-5 on posterior side

Question 23

metacarpophalangeal joint classification

Answer 23

synovial biaxial condyloid

Question 24

metacarpophanlangeal ligaments

Answer 24

thinkening of articular sides
funtion:
- limit flexion of digit
- prevent abduction and adduction of digits in flexion

Question 25

palmar ligaments (plates)

Answer 25

fibrocartligionus plates form part of articular surfaces grooved for long flexor tendon limit extension of digits

Question 26

deep transverse metacarpal ligaments

Answer 26

connect palmar ligaments of MCP joints 2-5 (keep heads together)

Question 27

interphalangeal joints

Answer 27

synovial uniaxial hinge

Question 28

IP joint collatersl ligaments

Answer 28

thickening of articular capsule and function to limit flexion of digit

Question 29

IP joint palmer plates

Answer 29

limit extension of digits
