hip&thigh2 Flashcards
where is the sacrotuberous ligament, sacrospinous ligament, greater sciatic foramen, lesser sciatic foramen
sacrotuberous=sacrum to ischial tuberosity, sacrospinous=sacrum to anterior inferior iliac spine
greater sciatic foramen between pelvis and axis
lesser sciatic foramen between spinotuberous and sacrospinous lig.
Where do gluetal muscles attach and what functions does it have
maximus and medius separated by posterior gluteal line and max muscle attach to macimus of bone. gluteus max and medius for extension. Medius and minimus separated by anterior gluteal line. gluteus minimus is a flexor
where does gluteus max attach to
posterior gluteal line+iliac crest, sacral tuberous lig. and gluteal tuberosity
what is the gluteus max supplied by and where does the nerve supply derive from
inferior gluteal n. derivation, L5,S1, S2 root
what is the extensor muscle of hip
gluteus max extends hip joint laterally against gravity and rotate hip joint
what causes lateral knee pain
stretch of iliotibial band
which muscles are hip abductors and what do they attach to
gluteus medius and minimus pulls greater trochanter up to hips
what is the role of pelvic stabiliser
prevent falls when walking, prevents pelvis tilting
what does trendelendburg’s sign show
wasting muscle on one side causing long term paralysis
what are the lateral rotators of the hips and where do they attach
piriformis, superior gemellus, inferior gemellus, quadratus femoris, obturator internus all attach to tronchanteric fossa
list the nerves of the gluteal regions and where they attach
ref. notes superior gluteal n., inferior gluteal n., sciatic n., pudendal n. (originates from S2-4) supplies perineum and exits greater sciatic foramen and attaches to trochanteric fossa, perforating cutaneous n.. They are all located around piriformis muscle
what are the arteries of the gluteal region
superior gluteal artery, inferior gluteal artery, internal pudendal artery
where would you want to inject in gluteus and why
upper lateral quandrant, awayb from sciatic nerve in lower medial quadrant. Find area by creating peace sign and alingning one finger on ASIS and other on iliac tubercle
what are the roots of the femoral n. and obturator n.
L2-4
what are the names of the 3 openings from abdomen
femoral (unnamed), obturator canal, greater sciatic foramen
Locate the muscles within each compartment of thigh and list its function
ref. notes
Anterior: psoas major, iliacus, rectus femoris=extension, vastus medialis=extensiokn, vastus lateralis=extension, sartorius=flexion and medial rotation, pectineus =flexion(innervated by anterior femoral n. and obturator n.)
Medial: adductor brevis, longus, magnus, gracilis=flexion and medial rotation, obturator externus,pectineus
Posterior: semimembranous=flexion and rotate knee medially, semitendinosus=flexion and rotate knee medially, biceps femoris=flexion and lateral rotation
Where do sartorius and adductor longus muscle attach
sartorius=ASIS to upper tibia
adductor longus=from pubic tubercle
Femoral triangle what are boundaries and what does it contain
Boundaries: Upper-inguinal ligament, medial=middle part of adductor longus, lateral=middle part of sartorius, roof=fascia lata, floor=iliopsoas, pectineus, adductor longus
Contents: Femoral vessels and nerves, deep inguinal lymph nodes
Label the popliteal fossa
ref. notes semitendinous, semimembranous, biceps femoris, gastrocnemius, plantaris, popliteal vessels, tibial n. right next to vessels, common fibular/peroneal n. lateral
