Answer 1

a) intercarpal joints

b) mid-carpal joints

Question 2

where are intecarpal joint found?

Answer 2

between carpals

Question 3

what type of joint are intercarpal joint

Answer 3

synovial, plane joints

Question 4

where are mid-carpal joints found?

Answer 4

between proximal and distal row of carpals

Question 5

what type of joint are mid-carpal joints?

Answer 5

synovial, hinge

Question 6

where are the carpometacarpal joints found?

Answer 6

between distal carpals and bases of metacarpals

Question 7

what are the articulations of the carpometacarpal joint of the thumb?

Answer 7

trapezium articulates with base of metacarpal 1

Question 8

what is different about the carpometacarpal joint of digit 1

Answer 8

digits 2-5 are synovial plane joints so they have linear translation/sliding/gliding, but digit 1 is a saddle joint so it has flexion/extension, abduction/adduction and opposition

Question 9

what are the 5 movements of the thumb?

Answer 9

1) flexion - across palm
2) extension - return to anatomical position
3) abduction - anterior to palm
4) adduction - return to anatomical position
5) opposition - thumb touches finger tips

Answer 12

1) collateral ligaments
2) palmar ligaments
3) deep transverse ligament of the palm

Question 13

what are collateral ligaments. what do they restrict?

Answer 13

capsular ligaments at sides of joint. restrict side to side movement

Question 14

what are palmar ligaments (plates)

Answer 14

thickening of joint capsule anteriorly

Question 15

Answer 22

synoval, condyloid bi-axial

Question 23

what movements occur at the radoiocarpal joint?

Answer 23

flexion/extension, abduction (radial deviation)/adduction (ulnar deviation)

Answer 27

Ulnar styloid process to the medial carpals (triquetrum and pisiform)

Question 28

what does the Ulnar/Medial Collateral Ligament (of the Radiocarpal Joint) restrict?
