medial compartment of thigh action;

- lateral compartment of leg action

does pec minor produce movement at shoulder ?

what muscles do?

NO!

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

connects lumbar and sacral plexuses

how does the femoral nerve enter the leg

underneath the inguinal canal

branches of sciatic nerve;

common fibular and tibias nerves

parts of humerus

head, greater and lesser tubercle, shaft contains anterior crest

capitulum, trochlea (ant)
M&L epicondyles & olecranon fossa (post)

scapula

functions of different muscles
acromion vs coracoid- which is more posterior

supraspinatus - ABduction
teres minor & infraspinatus -
subscapularis -

subscap- only one thats ANTERIOR

WHAT ATTACHES to greater tubercle of humerus

3 post rotator cuff muscles

supra, infraspinatus & teres minor

radial groove/spiral groove/ radial sulcus?

broad, shallow depression in shaft of humerus

- deep brachial artery and radial nerve pass through

ulna bone

coranoid process and trochlea notch (ant)
olecranon (post)
ulnar notch

nb head is inferior

syloid process

function of muscles - in relation to moving SCAPULA

pec minor
serratus anterior
trapezius
rhomboids
latissimus dorsi

their attachments ; to do!

PM; protraction and depression 
SA; elevation, protraction, ABduction 
T; elevation, depression, retraction
R; elevation &amp; retraction 
LD; extension ABduction, medial rotation -- prime mover of the arm

tip ; pair muscles together while learning them

what inserts onto the greater trochanter of femur ?

2) GLUTEAL TUBEROSITY

GT; G medius and minimus, piriformis

GLUTEAL TUBE; gluteus maximus

what foramen does piriformis pass through ?

greater sciatic formamen

why does fibula have an enlarged head

so it can insert on to lateral condyle of tibia

quadriceps proximal and distal attatchments

P; ? | D ; patella and tibial tubersoity via the patella tendon

with what carpal bone does the radius articulate with ?

scaphoid and lunate

type of joint is wrist joint

synovial; ELLIPSOID

WHAT ligament permits rotation of radial head or head of radius?

ANNULAR RADIAL LIGAMENT

RADIOULNAR JOINTS

proximal ; formed by radius head and radial notch of ulna | dital; ulnar head and ulnar notch of radius

medial or deltoid ligaments vs lateral ligaments functions attatchments

M/D; prevent over EVERSION (mEdia- Eversion) attatch; medial malleolus of tibia L; can get damaged by over inversion A; lateral malleolus of fibula lateral damage more easily than deltoid ones

pronators | - name & deep or superficial

pronator teres (superf) & quadratus (deep) keep image google in head

name for thumb & big toe

T; pollex | BT; hallux

function of dorsal and palmar interosseoi

D; ABduction of fingers | P; ADduction
