wrist and hand

Question 1

carpal bones proximal row

Answer 1

lateral to medial

scaphoid, lunate, triquetrum, pisiform- only seen anterior

Question 2

carpal bones distal row

Answer 2

lateral to medial

trapizium ( thumb ), trapazoid, capitate, hamate

Question 3

radiocarpal joint classified

Answer 3

synovial, biaxail, elipsoid

Question 4

structures of the radiocarpal joint

Answer 4

articular surface= distal end of radius, proximal row of carpals// articular disc of the radioulna joint so no ulna bone

articular capsule- attaches to margins
joint cavity- only occasionally communicates with radioulna joint

Question 5

triangular fibrocartledge complex

Answer 5

distal to radioulna artiular disc
ligaments involved- ulnotiquetral, ulnolunate, palmar and dorsal radiolna and ulna collateral

stabilise distal radioulnar and ulnocarpal joints
transmits and distrubutes force from carpal to ulna
helps complex wrist movement

Question 6

palmar radiocarpal ligament

Answer 6

unites radius and carpal bones on the palmar side
limits hand extension
ensures hand moves with forearm

RC JOINT

Question 7

dorsal radiocarpal ligament

Answer 7

unites radius and carpal bones on the DORSAL side
limits hand FLEXION
ensures hand moves with forearm

RC JOINT

Question 8

Radial collateral ligaments

Answer 8

styloid process to scaphoid/ trapizium

limit hand adduction

Question 9

ulna collateral ligaments

Answer 9

styloid process to traquatrum and pisiform

limit abduction

Question 10

mid carpal joint classified

Answer 10

synovial, compound joint

Question 11

mid carpal joint structure

Answer 11

between distal and proximal rows of carpal bones

joint cavity- extensive and irregular extends prox and distally bewteen the bones

the radial and ulnar collateral continue

dorsal and palmer intercarpal ligaments converge on capitate

Question 12

wrist complex flexion and extension

Answer 12

saggital plane// tranverse axis

flexion= radiocarpal > midcarpal
extension midcarpal > radiocarpal

Question 13

wrist complex abduction and adduction

Answer 13

coronal plane// anteroposterior axis

abduction= midcarpal > radiocarpal
Adduction= radiocarpal > midcarpal

Question 14

intercarpal joints classified

Answer 14

synovial, multiaxial plane

Question 15

intercarpal structures

Answer 15

extensive array of ligaments
flexor retinaculum acts as ligament by strapping down long tendons

scapulunate ligament
prevent lunate dislocating from scaphoid

Question 16

carpometocarpal thumb joint

Answer 16

synovial, biaxial, saddle

trapizium and base of first metacarpal

anterior oblique ligament= limit extension
posterior oblique ligament= limit flexion

thumb flex and extend= coronal plane/ anteroposterior axis

thum abduction/ adduction= saggital/ transverse axis

Question 17

carpometocapal 2-5

Answer 17

synovial multiaxial plane
2- trapazoid
3-capitate
4-humate
5-humate

with base of metacarpal

Question 18

palmer carpometatarsal ligament

Answer 18

distal row to m.carpal
2 bands each except 3 for 3rd digit
limit extension

Question 19

dorsal carpometatarsal ligament

Answer 19

each one 2 bands except the 5th with 1

limit fexion

Question 20

metocarpal phallangeal joints the knuckle

Answer 20

synovial biaxial condyloid

Question 21

collateral ligament of MCP joints

Answer 21

thcken articular capsule

limit flexion
prevent digits abduction and adduction when flexed

Question 22

palmar plates of MCP joint

Answer 22

fibrocartledge plates
from articular surface
grooved for long tendons

limit extension of digits

Question 23

deep transverse of MCP joint

Answer 23

connect palmer plates of MCP 2-5
WITH heads of metacarpals 2-5in

Question 24

interphallangeal joint hands

Answer 24

synovial/ uniaxial/ hinge

collateral lig- limit flexion

palmar lig- limit extension groove for long tendon
