Surface anatomy Week 3 Flashcards
how can you find the medial and lateral epicondyle to the humerus
these are the large bumps on by your elbow
what is the ulnar groove
this is the notch for the radial n. and it is on the medial epicondyle ( also called the funny bone )
what are some things found on the humerus
medial side= brachial artery just under the biceps
distal= spiral groove for the radial n
how do you know you have the ulna
it will not change with pronation or supination at proximal end
how to find the olecranon prcoess
this is the point of elbow and is the most bony part
how do you palpate the shaft of ulna
you start from OP and work your way down to the hand
how do you find the ulnar head
this is the round bony part on your medial side of your wrist ( and is proximal to the ulnar styloid)
what is the styloid process of ulna
point end of ulna and make sup the medial boundary of wrist joint
how do you konw you have the radius
this will rotate so the relative postion will change with pronation and supination
how do you find the radial head
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
what is the styloid process of radius
distal point of raduis on thumb side and makes up lateral bounder of wrist joint
how do you palpate dorsal tubercles of the radisu
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
what is in the proximal row of the carpal bones
thumb → pinky
scaphoid, lunate, triqueturm, pisiform
what is in the distal row of the carpal bones
thumb → pinky
trapezium, trapezoid, capitate, hamate
acronym for the bones
so long to pinky here come the thumb
what is the scaphoid
sits in the base of anatomic snuff box
- articulates wiht radius
what is the most commony fractures carpal bone
scaphoid
what s the most commonly dislocated carpal bone
lunate
what is the lunate
distal to dorals tubercles and when you felx your wrsit it should pop up then when you extend it disappers
what is the triquetrum
shaped like a triangel with 3 sides
– hard to paplate – under pisiform
what is the pisifomr
pea shaped and on top of the triquetum
- you can feel this
- under the pinky and it sticks up
what is the trapezium
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)
what is the trapeziod
this is on the inziod and shaped like a trapezoid and should line up with 2nd mc
what is the capitate
this look like it has a cap and lines up with 3 mc and is distal to lunate
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
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
what are the metacarpals
1-5 from thumb to pinky and btw cb and phalanges
what is the MCP joint (MC)
joint btw mc and phalanges
what are phalnages
fingers
singular phalax
what is the PIP and DIP joints
PIP= proximal middle phalanges
DIP=distal proximal phalanes
what is the IP joint
this is in the thumb inter phanagles join of the thumb
what is the biceps
most superfical with 2 head and act on 2 joint s
the bicep curl is how you can eminzitize this
what is the brachailis
deep to bicep and best palpated with C grip at distal arm and flex arm then supinate it
what is the brachioradialis
run form brachem to radius
palpate arm mid postion to restit flexion and can feel at distal arm
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
what is in the 2nd layer of forearm m.
FDS- block DIP and flex PIP and can feel under FAm.
what is in the 3rd layer of the forearm m.
FDP- block PIP and flex DIP then feel FA M.
FPL
what is in the 4th layer of the forearm m.
PQ
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
what is the tricpes
this has 3 heads and acts on 2 joints
how do you palpate the long head of tricpes
should and elbow extned can feel
how do you palpate the lateral head
flexed should and extend elbow
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
what are the extensors m of the forarem
ECRB ECRL ED ECU EI EDM
what makes you the anatomic snuffbow
apl
epb
epl
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
where can you find the ulnar n.
from ulnar groove of meoh to funny bone
where can you find the median n
run through cubital fossa
where can you find the radial n
wrap aroudn poster humers in spiral groove and can be traped in supinator m.
what is TAN
biceps brachii Tendon
brachial Artery
meian Nerve
** in the cubital foss
what is the radial collateral ligament (RCL)
leh wraps to radius and ulna
what is the ulnar collateral liagment (UCL)
3 parts to it -anterior -posterior -oblique BANDS
what is the anterior band of UCL
medoh to conroniod p of ulna
what is the posterior band of UCL
meoh to op of ulna
what is the oblique band of UCL
op of ulna to coronoid p of ulna
what is the annular ligament
wrap aroudn radial head to attach to ulna and is the proximal radio ulnar joint
