anterior & medial thigh Flashcards
pectineus origin
superior ramus of pubis
pectineus insertion
picteneal line of femur (inferior to lesser trochanter of femur)
pectineus action
- adduction of thigh
- flexion of thigh
- medial & lateral rotation of thigh
pectineus innervation
femoral nerve
(can see obturator nerve branches sometimes)
pectineus artery
medial femoral circumflex artery
obturator artery
sartorius origin
ASIS
sartorius insertion
proximal tibia: medial aspect
(superior aspect of medial surface)
sartorius action
- flexion, adduction. lateral rotation of thigh at hip
- flexion of leg at knee
sartorius innervation
femoral nerve

femoral artery
what 2 muscles compose the ilopsoas muscle?
- Iliacus
- Psoas major
iliacus origin
iliac fossa
sacrum
iliacus insertion
lesser trochanter of femur
iliacus action
- flexion of thigh at hip
- stabilize hip joint
- does these with psoas major (iliopsoas)
iliacus innervation
femoral nerve
iliacus artery
iliolumbar artery
psoas major origin
lumbar vertebra: lateral aspect of vertebral bodies & transverse processes
psoas major insertion
lesser trochanter of femur
psoas major action
postural muscle (active during standing. assists in controlled deviation of trunk)
iliopsoas action
- flexes thigh at hip
- flexes vertebral column
- stabilizes hip joint
psoas major innervation
L2-L4 anterior rami
psoas major artery
iliolumbar artery (lumbar branch)
iliopsoas action
- flexes thigh at hip
- flexes vertebral column
- stabilizes hip joint
