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
RECTUS FEMORIS M. ARTERY
descending branch of lateral femoral circumflex artery
RECTUS FEMORIS M. INNERVATION
femoral nerve
VASTUS INTERMEDIATE M. ORIGIN
superior 2/3 of the femoral shaft (anterior and lateral surfaces)
VASTUS INTERMEDIATE M. INSERTION
base of the patella forming part of the quadriceps tendon, and the tibial tuberosity via the patellar ligament
VASTUS INTERMEDIATE M. ACTION
extends the leg at the knee
VASTUS INTERMEDIATE M. ARTERY
descending branch of lateral femoral circumflex artery
VASTUS INTERMEDIATE M. INNERVATION
femoral nerve
VASTUS LATERALIS M ORIGIN
superior intertrochanteric line, the anterior and inferior greater
trochanter, the lateral edge of the gluteal tuberosity, and the
superior lateral lip of the linea aspera
VASTUS LATERALIS M INSERTION
lateral border of the patella forming part of the quadriceps
tendon, and then tibial tuberosity via the patellar ligament
- muscle fibers pass inferiorly and circularly
(internally) around the femur
- muscle belly is easily palpated along the anterolateral aspect of
the thigh during muscular contraction
