Anterior Thigh Flashcards
(23 cards)
Pectineus: Origin
Superior ramus of pubis
Pectineus: Insertion
Pectineal line of femur
Pectineus: Innvertaion
Femoral nerve (L2, L3) + Obturator nerve
Pectineus: Action
Adducts and flexes hip joint, medial rotation
Pectineus: Arterial supply
Medial circumflex femoral branch of femoral artery + obturator artery
Sartorius: Origin
Anterior superior iliac spine, superior part of notch inferior to it
Sartorius: Insertion
Superior part of medial surface of tibia
Sartorius: Action
Flexes, abducts, and laterally rotates hip joint, flexes knee
Sartorius: Arterial Supply
Muscular branches of femoral artery
Psoas major: Origin
T12-L5 vertebrae and discs between them; transverse processes of all lumbar vertebrae
Psoas major: Insertion
Lesser trochanter of femur
Psoas major: Innervation
Anterior rami of lumbar nerves (L1, L2, L3)
Psoas major and Iliacis: Action
Flexes and stabilizes hip joint; postural
Psoas major and iliacis: Arterial Supply
Lumbar branch of iliopsoas branch of internal iliac artery
Rectus femoris: Origin
Anterior inferior iliac spine, ilium superior to acetabulum
Rectus femoris, Vastus lateralis, Vastus intermedius: Arterial Supply
Lateral circumflex femoral artery
Vastus lateralis: Origin
Greater trochanter, lateral lip of linea aspera
Vastus medialis: Origin
Intertrochanteric line, medial lip of linea aspera
Vastus medialis: Arterial Supply
Femoral artery, deep femoral artery, and superior medial genicular branch of popliteal artery
Vastus intermedius: Origin
Anterior and lateral surfaces of femur shaft
Quadriceps: Insertion
Via common tendinous (quadriceps tendon), independent attachments of base of patella, indirectly via patellar ligament to tibial tuberosity, VM and VL attach to tibia and patella via aponeurosis (medial and lateral patellar retinacula)
Quadriceps: Innervation
Femoral nerve (L2, L3, L4)
Quadriceps: Action
Extend knee joint, RF also stabilizes hip joint and helps iliopsoas flex hip joint
