Flashcards in Lecture 4.2 Deck (18):
1

The radiocarpal and intercarpal joints are ______

synovial

2

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

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

3

where are the intercarpal and midcarpal joints located?

4

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

condyloid joint

5

Identify the ligaments of the wrist

6

true or false

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

true

7

true or false

At the radicarpal joint Radial deviation is greater than ulnar deviation

false

other way around

8

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

 

The radial styloid process extends further distally

9

The capsule of the wrist joint is reinforced by:

 

Palmar radiocarpal

palmar ulnocarpal

dorsal radiocarpal ligaments

10

Where is the saddle joint?

Between metacarpal 1 and the trapezium

11

What joint is betwen the proximal falanges and metacarpals?

 

Which ligaments reinformce this joint?

condylar

pamlar ligament

medial/lateral colateral ligaements

12

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

 

deep transverse metacarpal ligaments

13

 

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

false

 

there is an absense of sheaths where lumbrical muscles attach

14

True or False

The annular fibres in the hand are circular

yes,

 

cruciform also criss-cross

15

true or flase

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

true

 

leads to "pins and needle"

 

further contraint leads to loss of senesation

16

Ulnar nerve damage at the distal end causes what?

intrinsic muscle wasting, in the ring and little fingers

knuckle joints hyperextended (paralysed lumbricles)

interphalageal joints are flex paralysed interosssei)

17

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

humerus
