A5; MSK Flashcards
FUNCTION OF latissimus Dorsi
- extension
- aDduction
- medial rotation of upper lim
PRIME MOVER OF THE ARM
function of G.medius & minimus
ABduction
muscles in anterior compartment of thigh name
- their distal attatchment
quadriceps
patella down to tibial tuberosity via the patella tendon
limbs rules for flexion and extension
upper limb;
ant- flexion, post- extension
lower limb;
ant- extension, post- flexion
muscles of anterior forearm
- flexor carpi radialis - near radius bone
- flexor digitorum superficialis
note; pronator teres (superficial) & quadratus (deep)
think of google diagram
posterior forearm
- abductor pollicis longus
- extensor digitorum
- extensor carpi ulnaris
VAN
vein
artery
nerve
v common order from medial to lateral
nb for identifying sciatic nerve on cadavers
its HUGE!
- medial compartment of thigh action;
- lateral compartment of leg action
M; ADduction
L; EVERSION – different (fibulas brevis & longus)
does pec minor produce movement at shoulder ?
what muscles do?
NO!
DO; pec major, lat dorsi, deltoid, biceps brachii (long head)
whats wrist drop
inability to extend the wrist at the forearm
radial nerve is usually damaged
anterior compartment of leg muscles name
- main action at foot
- in order from MEDIAL to LATERAL
tibialis anterior
extensor digitorum longus (SPLITS )
extensor hallucis longus
action; dorsi flexion which is ; extension
posterior compartment of leg muscles
superficial ; GASTROCNEMIUS & soleus ?
deep; tibialis posterior, flexor hallucis longs, flexor digitorum longus
what muscles cause eversion and inversion
I; tibialis anterior & posterior
E; fibularis brevis and longus
what does the lumbar sacral trunk do
connects lumbar and sacral plexuses
