anterior and medial thigh Flashcards
pectineus origin
superior ramus of pubis
pectineus insertion
pectineal line of femur
pectineus innervation
femoral nerve
pectineus action
-adducts and flexes hip joint
sartorius origin
anterior superior iliac spine
sartorius insertion
superior part of medial surface of tibia
sartorius innervation
femoral nerve (L2, L3)
Sartorius action
- flexes, abducts and laterally rotates hip joint
- flexes knee joint
Four parts of quadriceps femoris
- Rectus femoris
- Vastus lateralis
- Vastus medialis
- Vastus intermedius
Rectus femoris origin
anterior inferior iliac spine
vastus lateralis origin
- greater trochanter
- lateral lip of linea aspera
vastus medialis origin
- medial lip of linea aspera
- intertrochanteric line
vastus intermedius origin
-anterior and lateral surfaces of shaft of femur
Quadriceps femoris insertion (all four)
Quadriceps tendon
Quadriceps femoris innervation (all four)
femoral nerve
Quadriceps femoris action (all four)
- Extends knee joint
- rectus femoris only: flex hip
adductor longus origin
body of pubis inferior to pubic crest
adductor longus insertion
middle third of linea aspera of femur
adductor longus innervation
obturator nerve
adductor longus action
adducts hip joint
muscles of the anterior thigh
- pectineus
- iliopsoas
- sartorius
- quadriceps femoris (four parts)
all innervated by femoral except of psoas major
Quadriceps tendon
- the four muscle tendons of quadricepts femoris come together to make this
- it becomes patellar ligament at knee
Patellar ligament
- patella is embredded in there
- continuation of quadriceps tendon
Muscles of the medial thigh
- “adductor group”
- adductor longus
- adductor brevis
- adductor magnus
- gracilis
- obturator externus
all innervated by obturator excepts for hamstring part of adductor magnus
