Anterior Thigh Flashcards
what are the muscles of the anterior compartment of the thigh (9)
- psoas major
- iliacus
- tensor fascia lata
- sartorius
- rectus femoris
- vastus medialis
- vastus lateralis
- vastus intermedius
- articularis genu
tensor fascia lata:
origin
insertion
action
antagonist
innervation
- lateral iliac crest
- it band to lateral condyle of tibia
- knee & pelvic stabiliser
hip flexion and medial rotation - lateral rotators
- superior gluteal nerve L4, L5
sartorius:
origin
insertion
action
antagonist
innervation
- ASIS
- medial condyle of tibia
- knee flexion, hip flexion, ext hip rotation, internal leg rotation, abduction
- opposite of above
- femoral nerve L2, L3, L4
rectus femoris:
origin
insertion
action
antagonist
innervation
- AIIS
- tibial tuberosity via patella tendon
- knee ext, hip flexion
- hammies
- femoral nerve L3, L4
vastus lateralis
origin
insertion
action
antagonist
innervation
- greater troch, lat femur & linea aspera
- tibial tuberosity via patella tendon
- knee extension

- femoral nerve L2, L3, L4
vastus medialis
origin (5)
insertion
action
antagonist
innervation
- intertrochanteric line, spiral line, linea aspera, supra condylar line, aductor magnus
- tibial tuberosity via patella tendon

hip flexors: psoas major
origin
insertion
action
antagonist
innervation
- 12th thoracic and lumbar vertebrae

- hip flexion
- gluteus maximus, hammies
- femoral nerve L1, L2, L3
hip flexor: iliacus
origin
insertion
action
antagonist
innervation
- upper 2/3 of iliac fossa
- lesser trochanter
- hip flexion
- gluteus maximus and hammies
- femoral nerve L2,L3
name the cutaneous nerves of the thigh (7)
- medial femoral cutaneous nerve
- intermediate femoral cutaneous nerve
- saphenous nerve
- lateral femoral cutaneous nerve
- obturator
- ilioinguinal
- genitofemoral
what are the arteries of the anterior thigh, from aorta (6)
*common iliac
-external iliac
* femoral artery
* profunda femoris
* medial and lateral femoral circumflex artery
* popliteal artery
which veins supply the femoral vein (3)
- the great saphenous vein
- the profunda femoris vein
- the popliteal vein
describe the great saphenous vein (4)
- superficial
- runs from ‘hallux to bollocks’
- varicose veins
- longest vein in the body
broadly speaking, what is the role of lymphatics
- generally follow the course of veins
- drain into lymph nodes (filtering)
- all drain into venous system
