Lecture 4.2

Question 1

The radiocarpal and intercarpal joints are ______

Answer 1

synovial

Question 2

The radiocarpal (wrist) joint is between distal ___ and scaphoid, ____and triquetrum

Answer 2

The radiocarpal (wrist) joint is between distal radius and scaphoid, lunate and triquetrum

Question 3

where are the intercarpal and midcarpal joints located?

Answer 3

Question 4

A ________joint (like the radiocarpal oint) has a concave/convex surface

Answer 4

condyloid joint

Question 5

Identify the ligaments of the wrist

Answer 5

Question 6

true or false

There are ligaemnts that stop excessive ulnar deviation from the promial row of the carpal bones

Answer 6

true

Question 7

true or false

At the radicarpal joint Radial deviation is greater than ulnar deviation

Answer 7

false

other way around

Question 8

Why can the hand be adducted to a greater degree than abducted?

Answer 8

The radial styloid process extends further distally

Question 9

The capsule of the wrist joint is reinforced by:

Answer 9

Palmar radiocarpal

palmar ulnocarpal

dorsal radiocarpal ligaments

Question 10

Where is the saddle joint?

Answer 10

Between metacarpal 1 and the trapezium

Question 11

What joint is betwen the proximal falanges and metacarpals?

Which ligaments reinformce this joint?

Answer 11

condylar

pamlar ligament

medial/lateral colateral ligaements

Question 12

The ____ ______ ________ ligaments help stablise the skeletal framework of the hand, by linking the heads of the metacarpal bones together

Answer 12

deep transverse metacarpal ligaments

Question 13

The synovial sheaths (fibrous didgital sheaths) in the hand are continuous from the flexor retinaculum to the distal phalange

Answer 13

false

there is an absense of sheaths where lumbrical muscles attach

Question 14

True or False

The annular fibres in the hand are circular

Answer 14

yes,

cruciform also criss-cross

Question 15

true or flase

in carpal tunnel syndrom, it is the vascular supply of the median nerve that is first affected

Answer 15

true

leads to “pins and needle”

further contraint leads to loss of senesation

Question 16

Ulnar nerve damage at the distal end causes what?

Answer 16

intrinsic muscle wasting, in the ring and little fingers

knuckle joints hyperextended (paralysed lumbricles)

interphalageal joints are flex paralysed interosssei)

Question 17

Wrist drop is from radial nerve compression near the ______ (bone)

Answer 17

humerus
