Q

Coracoacromial ligament function

A
  • prevents superior displacement of humerus
26
Q

muscles bordering axilla anteriorly and posteriorly

A

post: lats dorsi
ant: pec major

27
Q

brachial plexus cords order

A

lateral
posterior
medial

28
Q

muscles in anterior forearm/ flexors origin

muscles in posterior forearm/ extensors origin

A
  • medial epicondyle

- lateral epicondyle (of HUMERUS )

29
Q

WHAT movements does annular ligament assist

A

pronation and supination

30
Q

deep flexor tendons

  • aka
  • function
A
  • flexor digitorum profundus

- flex dip joints

31
Q

nerve supply of dorsal and ventral interosseoi

A

uLNAR nerve

32
Q

acetabular labrum: what is it

A

cartilage that surrounds the acetabulum

33
Q

tibial plateau: where is it located and its contents

A

v top surface of tibia

- contains M&L condyles and intercondylar eminence

34
Q

function of gluteus medius and minimus (2)

A
  • ABduction

- keeps pelvis straight when we walking

35
Q

hamstring ,muscles from medial to lateral:
action @ knee
action @ hip

A

semimembranosus
semitendinosus
biceps femoris

flexion
extension

36
Q

where does the SARTORIUS muscle originate from

A

ASIS of pelvis and runs inferomedially

37
Q

femoral artery = a branch of:

A

external iliac artery

38
Q

where does the Great Saphenous vein drain to

where does it start - at whoch malleolus

A

femoral vein

medial malleoulus

39
Q

butt injection - safest in which quadrant

A

upper lateral to avoid the sciatic nerve

40
Q

how does the femoral nerve enter the leg?

A

underneath the inguinal canal

makes sense considering the borders of the femoral triangle

41
Q

revise all the arteries and veins

A

anatomy book

42
Q

what carpal bone attatches to the tibia

A

TALUS

43
Q

Medial ligament of the foot aka

A

DELTOID ligament

44
Q

how to distinguish between fibularis brevis and longus
by origins

where of they run fot the most part from the femur, i.e near fibula or tibia, M or L etc

A

longus: starts at the top of the femur, travels down to its distal insertion: medial cuneiform of the 1st metatarsal
brevis: covered by the longus for the most part. starts more distally by the femur. distal insertion is the 5th metatarsal

posterior to the LATERAL malleolus - fibula

45
Q

identify the structures at the medial malleolus:

A

tibialis posterior
post tibial artery and veins
tibial nerve

flexor hallucis longus
flexor digitorum longus

46
Q

what nerves cause INVERSION of the foot

A

muscles: TP & TA

thus whatever nerves innervate them: deep fibular and tibial nerve

47
Q

anterior part of the foot is mainly supplied by what nerve

A

superficial fibular nerve!

48
Q

what is the spermatic cord:

A

formed by the vas deferens with tissue layering it.
starts within the pelvis quite high up
wiki images is v good
eg. one of the layers comes from the aponeurosis of the external oblique muscle

49
Q

costal and dorsal meanings

A

costal: anterior
dorsal: posterior

50
Q

which tuberosity on the humerus is most laterally located

A

greater tuberosity

51
Q

humerus: anatomical vs surgical neck

A

NB distinction on diagram

52
Q

trochlea or capitulum = medial or lateral

A 
trochlea = medial 
capitulum = lateral

this makes sense as trochlea of humerus and trochlear notch of ULNAR bone which is medial articulate

53
Q

brachial plexus: rhyme

A 
rude - roots 
tennagers - trunks 
drink - divisions 
crazy - cords (lateral, posterior, medial)
naggins - nerves
54
Q

biceps brachii action at forearm

A

SUPINATION very minimal contribution

55
Q

FOREARM MUSCLE ACTIONS:

A

ant: flexion and pronation
post: extension and supination

56
Q

brachial artery splits into

A

radial and ulnar artery

57
Q

use of median cubital vein

A

venepuncture - taking blood

58
Q

deep flexor tendons function

lumbricals function

A
  • flexion of DIP joints

- flexion of MCP. extension of PIP and DIP joints

59
Q

what do we find deep to the flexor retinaculum and what contents lie in this space

A
  • carpal tunnel: median nerve and long flexor tendons
60
Q

actions possible at the sacpulathoracic joint

A

elevation, depression, protraction, retraction, retraction

61
Q

function of latisumus dorsi

A

ADduction
extension
rotation

62
Q

muscle in the forearm

A

ant: pronator teres, flexor carpi radialis, flexor digitorum superficialis
post: abductor pollicis longus, extensor digitorum, extensor carpi ulnaris (extension of the
