what makes up proximal radioulnar joint
head of radius, radial notch of ulna
annular ligament attaches to blank then wraps around blank
ulna, radial head
radial head subluxing is called blank elbow and is from quickly pulling arm/traction and is most common in young children
nursemaids
distal radioulnar joint is a blank joint
pivot
distal radioulnar joint is made up of blank and blank

four bones of radiocarpal joint
radius, scaphoid, lunate, triquetrum
ligaments of wrist…. this one pulls wrist into supination, while this one pulls wrist into pronation

pronator teres, flexor carpi radialis, palmaris longus, flexor carpi ulnaris
intermediate layer of anterior forearm muscles
flexor digitorum superficialis
deep layer of anterior forearm muscles

flexor digitorum profundus goes to the blank phalanx
distal
tendons of intermediate layer attach at blank
phalanges 2-5
deep muscle tendons attach to blank
distal phalanges 2-5
ulnar nerve innervates blank muscles of anterior forearm
flexor carpi ulnaris, medial half of flexor digitorum profundus
radius fractures are most common in this population
women older than 50
radius fracture in children can be problematic because it could interfere with blank
growth
brachioradialis innervation
radial nerve
3 outcrop muscles that act on the blank
thumb
3 outcrop muscles
abductor pollicis, extensor pollicis brevis, extensor pollicis longus
antebrachium muscles are innervated motorly by blank
deep radial nerve
extensor indicis is innervated by blank
posterior interosseous nerve
radial artery continues as the blank
deep palmar arch
ulnar artery continues as the blank
superficial palmar arch
parts of the common interosseous artery
anterior, posterior, recurrent
common interosseous artery is the blank vessel of the antebrachium
deepest
contents of anatomical snuff box
radial artery, scaphoid
ulnar nerve is usually injured at blank
medial epicondyle
fracture of the scaphoid is the most common carpal and causes pain in the blank side of the wrist during dorsiflexion and abduction of the hand…. eventually can lead to blank
lateral, djd
cmc joint is a blank joint but cmc 1 is very blank like
planar synovial, saddle like
contents of carpal tunnel
4 tendons of fds, 4 tendons of fdp, fpl tendon, median nerve
imc joints are blank
synovial planar
carpal tunnel syndrome is when the median nerve is compressed due to things like blank of blank
inflammation, tendons
palmar carpal ligament blends with the blank
flexor retinaculum
palmar carpal ligament on posterior side is continuous with the blank
extensor retinaculum
fascia compartments of palm
palmar fascia, palmar aponeurosis, medial fibrous septum, lateral fibrous septum
there are blank palmar interossei and blank dorsal interossei
3, 4
median nerve innervates blank muscles and blank lumbricals
thenar, 1,2
thenar muscles innervation
recurrent branch of median
blank innervates most of hand
deep branch of ulnar nerve
dorsal interossei action
abduction
palmar interossei action
adduction
3rd digit has no blank because its action is only blank
palmar interossei attachment, abduction
first layer of palm
palmar aponeurosis
2nd layer of palm
palmaris brevis (tunnel of guyon)
3rd layer of palm
thenar muscles, hypothenar muscles, tendons of flexor digitorum superficialis, flexor retinaculum, digital sheaths
mcp joints are blank
condyloid synovial
ip (dip/pip) joints are blank and have blank
hinge synovial, collateral ligaments
flexor pollicis brevis DEEP head innervation
ulnar (not medial)
1st lumbrical acts on blank
2nd digit
digit that doesnt get a palmar interossei muscle
3, middle finger
dorsal interossei are blank
bipennate
palmar interossei are blank
bipennate
finger not getting a dorsal interossei muscle
pinky
flattenings of extensor tendons
expansion
extensor tendons attach to blank and blank phalanges
middle, distal
annular ligaments and cruciform ligaments hold down blank
tendons
annular ligament is aka
pulley
major arteries of forearm/hand
ulnar, radial
radial artery turns into blank arch
deep palmar
ulnar artery turns into blank arch
superficial palmar
superficial and deep palmar arches meet at blank
common digital artery
only muscles of hand that ulnar nerve doesnt innervate
1-2 lumbricals, thenar muscles
radial nerve cutaneously innervates part of blank of hand
dorsum
ulnar nerve cutaneously innervates skin by blank
4/5 digits
median nerve severing causes loss of blank of these digits
flexion, 1-3
