Q

how do you find the radial head

A

this articulates w/ captulum of humerus and held by annular ligament to ulna

    • this would be the raidoulnar joint
    • palpate by usinga pinch grip then rotate arm distal to elbow joint

Q

how do you palpate dorsal tubercles of the radisu

A

this acts as a point/ pully for EPL and is in like wiht 2nd and 3rd mc
– you can feel for these medailly from the radial styloid process

Q

what is the trapezium

A

1st on distal row this i fits the thumb and there is a groove for flexor tendons with thumb it create saddle joint and can feel shape btwe MC( thumb) and CB ( zium)

Q

what is the trapeziod

Study These Flashcards
A

this is on the inziod and shaped like a trapezoid and should line up with 2nd mc

24
Q

what is the capitate

Study These Flashcards
A

this look like it has a cap and lines up with 3 mc and is distal to lunate

25
what is the hamate
this is under the pinky and has a hook | can feel by putting IP joint of thumb on pisifrom and push inward. this will feel hard and will hurt a bit
26
what is the tunnel of guyon
this is the ulnar cannal and the hook of hamat and pisiform form this and ulanr n runs through it
27
what are the metacarpals
1-5 from thumb to pinky and btw cb and phalanges
28
what is the MCP joint (MC)
joint btw mc and phalanges
29
what are phalnages
fingers | singular phalax
30
what is the PIP and DIP joints
PIP= proximal middle phalanges | DIP=distal proximal phalanes
31
what is the IP joint
this is in the thumb inter phanagles join of the thumb
32
what is the biceps
most superfical with 2 head and act on 2 joint s | the bicep curl is how you can eminzitize this
33
what is the brachailis
deep to bicep and best palpated with C grip at distal arm and flex arm then supinate it
34
what is the brachioradialis
run form brachem to radius | palpate arm mid postion to restit flexion and can feel at distal arm
35
what is in the 1st layer of the forearm m.
- PT-pronate fa can feel at meoh - FCR- radial devatate wrist can feel - PL- oppostion thumb and pinky then flex hand - RCU- ulnar deviates wrist
36
what is in the 2nd layer of forearm m.
FDS- block DIP and flex PIP and can feel under FAm.
37
what is in the 3rd layer of the forearm m.
FDP- block PIP and flex DIP then feel FA M. | FPL
38
what is in the 4th layer of the forearm m.
PQ
39
how can you find the 1st layer ( trick)
``` place your palm on the medial epicondly of humerus and point fingers toward thumb side, index finers to pinky is numbered 1-4 1pt 2fcr 3pl 4fcu ```
40
what is the tricpes
this has 3 heads and acts on 2 joints
41
how do you palpate the long head of tricpes
should and elbow extned can feel
42
how do you palpate the lateral head
flexed should and extend elbow
43
what is the anconuse
small triangle shpaed over lateral epicondlyeand assist with last few degrees of elbow extension palpate --hyperextend and feel late epicondly of humerus
44
what are the extensors m of the forarem
``` ECRB ECRL ED ECU EI EDM ```
45
what makes you the anatomic snuffbow
apl epb epl
46
what does FOOSH mean
fall on an out stretched head | -- when everything is extendeed you fall is when you can really hurt and fracture things in the hand and arm
47
where can you find the ulnar n.
from ulnar groove of meoh to funny bone
48
where can you find the median n
run through cubital fossa
49
where can you find the radial n
wrap aroudn poster humers in spiral groove and can be traped in supinator m.
50
what is TAN
biceps brachii Tendon brachial Artery meian Nerve ** in the cubital foss
51
what is the radial collateral ligament (RCL)
leh wraps to radius and ulna
52
what is the ulnar collateral liagment (UCL)
``` 3 parts to it -anterior -posterior -oblique BANDS ```
53
what is the anterior band of UCL
medoh to conroniod p of ulna
54
what is the posterior band of UCL
meoh to op of ulna
55
what is the oblique band of UCL
op of ulna to coronoid p of ulna
56
what is the annular ligament
wrap aroudn radial head to attach to ulna and is the proximal radio ulnar joint
