ANTERIOR MUSCLES OF THE THIGH Flashcards
how is the anterior compartment of the thigh broken down?
superficial -tensor fasciae latae m -sartorius m intermediate -rectus femoris m deep -vastus intermediate m -vastus lateralis m -vastus medialis m -articularlis genu m.
what muscles make up the quadriceps m.
rectus femoris m
vastus medialis m
vastus intermedialis m
vastus lateralis m
TENSOR FASCIAE LATAE M. ORIGIN
lateral lip of the iliac crest, anterior to iliac tubercle (and fascia lata)
TENSOR FASCIAE LATAE M. INSERTION
iliotibial band which attaches at
Gerdy’s tubercle - courses
inferiorly along the lateral aspect
of the thigh
TENSOR FASCIAE LATAE M. ACTION
flex and abduct the thigh, This stabilizes the hip during gait.;
extend the leg, This stabilizes the knee during gait.
TENSOR FASCIAE LATAE M. ARTERY
lateral femoral circumflex artery
and superior gluteal artery
TENSOR FASCIAE LATAE M. INNERVATION
superior gluteal nerve
SARTORIUS M. ORIGIN
anterior superior iliac spine (and fascia lata)
SARTORIUS M. INSERTION
proximal medial shaft of the tibia -forms part of the pes anserinus -courses inferiorly from the anterolateral aspect of the thigh to the posteromedial aspect of the knee
SARTORIUS M. ACTION
flex and laterally rotate the thigh; flex the leg
all combined is the tailor position
SARTORIUS M. ARTERY
Femoral artery
SARTORIUS M. INNERVATION
Femoral nerve
RECTUS FEMORIS M. ORIGIN
Straight Head / Anterior Head
- anterior inferior iliac spine
Reflected Head / Posterior Head
- iliac part of
acetabular rim, externally
RECTUS FEMORIS M. INSERTION
base of the patella forming part of the quadriceps tendon, and then to the tibial tuberosity via the patellar ligament
- muscle belly is easily
palpated during muscular contraction
RECTUS FEMORIS M. ACTION
extend the leg at the knee assists iliopsoas with flexion of thigh
