thigh muscles Flashcards
muscles of anterior compartment
iliospoas
quadriceps femoris
sartorius
pectineus
innervation of anterior thigh muscles
femoral nerve
iliopsoas - attatchmennts
psoas major arises lumbar vertebara
iliacus originates from iliac fossa of pelvis
insert onto lesser trochanter of femur
iliopsoas - action
flex thigh at hip joint
iliopsoas - innervation
psoas major - anterior rami L1-3
illiacus - femoral nerve
muscles of quadriceps femoris
vastus lateralis
vastus intermedius
vastus medalis
rectus femoris
actions of quadriceps femoris
vastus lateralis, intermedius + medalis: extend knee joint & stabilise patella
rectus femoris: flex hip joint and extend knee
sartorius attachments
ASIS to superior, medial surface tibia
sartorius actions
hip: flexion, abduction, lateral rotation
knee: flexion
pectineus attatchments
pectineal line of pelvis to pectineal line posterior femur
pectineus actions
adduction and flextion hip
muscles of medial compartment
adductor magus adductor longus adductor brevis obturator externus gracilis
muscles of medial compartment nerve supply
obturator nerve
gracilis actions
adduct hip
flex knee
obturator externus actions
adduct and lateral rotation hip
muscles of posterior compartment
hamstrings:
- biceps femoris
- semitendinosis
- semimembranous
muscles of posterior compartment innervation
sciatic nerve
biceps femoris actions
knee flexion
hip extension
hip + knee lateral rotation
semitendinosus actions
flexion knee
extention hip
medial rotation hip and knee
semimembranosus actions
flex knee
extend hip
medial rot knee and hip
