Q

action: medial com of thigh

Study These Flashcards
A

adduct the hip

25
action: post com of thigh
hip extensors | knee flexors
26
action: ant com of leg
dorsiflex foot and extend digits
27
action: lateral com of leg
evert the foot
28
action: post com of leg
plantarflex foot, flex digits
29
muscles in: ant com of thigh
- sartorius - quadriceps femoris - tensor fascia latae
30
muscles in: medial com of thigh
- gracilis - pectineus - adductor longus/ brevis/ magnus
31
muscles in: post com of thigh
- biceps femoris - semitendinosus - semimembranosus
32
muscles in: ant com of leg
- tibialis ant - extensor hallucis longus - extensor digitorum longus - fibularis teritius
33
muscles in: lateral com of leg
- fibularis longus | - fibularis brevis
34
muscles in: post com of leg
- gastrocnemius - soleus - plantaris - deep group
35
nerve supply of lower limbs:
- lumbar plexus (L1 - L3/4) | - sacral plexus (L4 - S3)
36
arterial supply: first part
- common iliac aa. - > external/ internal iliac aa. - > femoral/ profunda femoris aa.
37
when does ext iliac become femoral aa:
- crosses over the inguinal ligament
38
arterial supply: part 2
popliteal aa. -> anterior/ post tibial arteries
39
venous drainage: 2 parts
- deep veins (follow arteries) | - superficial (subcutaneous ct.) drains into deep veins
40
venous drainage: veins
common iliac v -> internal/ ext iliac vein -> inferior/ superior gluteal veins -> obturator v -> femoral vein -> popliteal v -> anterior/ post tibial veins small and great saphenous veins (superficial) -> medial/ lateral marginal v -> dorsal venous arch
41
= pelvis:
os coxae | - sacrum and coccyx
42
parts of hip bone:
ilium, pubis, ischium
43
pelvis brim:
promontory of sacrum, alae of sacrum, arcuate line, pecten pubis, pubic crest - greater and lesser (false/ true)
44
sex differences of female:
female: - pelvic inlet circular - pubic arch larger (80-85˚) - ischial spine don't project far medially
45
sex differences of male:
- pelvic inlet heart-shaped - pubic arch smaller (50-60˚) - ischial spine project farther medially
46
hip joint: classification
synovial ball and socket
47
hip joint: articulating surfaces
- head of femur | - acetabulum of pelvis (lunate) with labrum
48
hip joint: ligaments (7)
- iliofemoral lig - ischiofemoral lig - pubofemoral lig - acetabular labrum - zona orbiularis - transverse acetabular lig - lig of head of femur
49
hip joint: movements
- flex/ ext - abd/ add - medial/ lateral rotation (moving greater trochanter forward and backwards)
50
stabilising factors of hip joint:
- deep socket - strong ligaments - muscles surrounding joint
51
capsular ligaments of hip joint: and features which help stabilise
illiofemoral lig - pubofemoral lig - ischiofemoral lig - all 3 ligs spiral around each other so when one lig is relaxed, another would always be taut
52
sacroiliac joint: classification
synovial plane
53
sacroiliac joint: articulating surfaces
auricular surface of ilium, auricular surface of sacrum
54
sacroiliac joint: ligaments
- interosseous lig - anterior sacroiliac lig - post sacroiliac lig - sacrotuberous lig - sacrospinous lig
55
pubic symphysis: classification
cartilaginous symphysis
56
pubic symphysis: articulating surfaces
pubic bones, symphyseal surfaces (fibrocartilage disc)
57
pubic symphysis: ligaments
- superior pubic | - inferior pubic
58
how much of the femoral and humeral head accepted?
glenoid cavity: 1/3 | acetabulum: 1/2
