ligament Flashcards
Function of the radial collateral ligament
Prevents adduction
FUnction of ulnar collateral ligament
prevent over abduction
Palmar radiocarpal ligament-
prevents over extension
Dorsal radiocarpal ligament
radius up to triquetrum- prevents over flexion
What do ulnaris and radialis muscles do
Adduction, abduction respectively
What is the function of the triangular fibrocartilage complex
stabilises the distal radioulnar and ulnocarpal joints + distributes load from carpals to ulna
Movement of the glenohumeral, steronoclavicular, acromioclavicular, scapulothoracic joints
Gleno: ad/ab, F/E, M/L
Sterno: F/E, Ab/Ad
Acromio: F/E, Ab/ Ad
Scapulo, M/L
Function of the:
corocohumeral
glenohumeral
corocoacromial
- stablises head of the humerus to glenoid cavity
- connects to glenoid cavity
- extends the coracoid process to the acromion of scapula
function of
transverse ligament
costoclavicular
sternoclavicular
-stablises odentoid process
- stabilises the sternoclavicular join by limiting movement
- restricts clavicle movement by superior displacemet
function of
acromioclavicular
conoid part of coracoclavicular
trapezoid part of coracoclavicular
- reinforces joint capsule and prevents it from moving back for all 3
action of the radioulnar joint
pronation, supination
What movements are in
radiocarpal
MCP
PI
DI
Interphalangeal
- F/E
- F/E, AB/AD
- F/E
- F/E
- F/E, AB/AD
Function of the
dorsal radiocarpal
palmar radiocarpal
palmar ulnocarpal
- stabilise wrist for pronation
- limit full flexion
- attaches styloid to lunate/ triquetral
function of
dorsal intercarpal
palmar intercarpal
dorsal carpometacarpal
palmar carpometacarpal
- stabilise movement for F/E, AD/AB
- restrains dorsal displacement of prox rows of carpal bones
- connects carpal and metacarpal ligament
function of
metacarpophalangeal collateral/ palmar/ deep transfverse ligaments
AB/AD, F/E of fingers
function of interphalangeal joint of collateral/ palmar ligaments
restricts over AB/AD rotation
