CRANIAL MUSCLE OF THIGH

Quadriceps femoris muscle

4 muscles on the cranial femur deep to tensor fascia latae

Cranial Thigh muscle Sub-Group

knee extensors

Cranial Thigh muscle

Quadriceps femoris Tensor fasciae latae

Cranial Thigh muscle Innervation

Quadriceps femoris- femoral nerve Tensor fasciae latae- cranial gluteal nerve

Cranial Thigh muscle Additional Action

Quadriceps femoris- rectus femoris flexes hip Tensor fasciae latae- flex hip

Patella

a large sesamoid bone embedded in the tendon of the quadriceps femoris without minimal extension

Insertion of Tensor fascia latae muscle

lateral femoral fascia (fascial latae wraps around tibia)

Origin of Vastus intermedius muscle

proximal femur

Origin of Vastus lateralis muscle

proximal femur

Origin of Vastus lateralis muscle, Vastus medialis muscle, and Vastus intermedius muscle

proximal femur

Origin of Vastus medialis muscle

proximal femur

Rectus femoris muscle

straight muscle on the femur most cranial head group round muscle on cross section which extends from the ilium, cranial to the acetabulum, to the tibial tuberosity

Action of Tensor fascia latae muscle

tense the lateral femoral fascia flex the hip joint extend the stifle/hip joint

Vastus lateralis muscle

the big lateral head arises from the proximal part of the lateral lip of the femur fuses with the distal portion of the rectus femoris

Vastus medialis muscle

the big medial head lies on the medial side of the rectus femoris originates on the proximal portion of the medial lip of the femur and fuses with the distal portion of the rectus femoris

Insertion of Quadriceps femoris muscle

tibial tuberosity

Tensor fascia latae muscle

triangular shaped muscle lies distal to the middle gluteal muscle short with a long fascial attachment

Origin of Tensor fascia latae muscle

tuber coxae adjacent part of the ilium

Origin of Rectus femoris muscle

tuberosity for rectus femoris m

Vastus intermedius muscle

between the Vastus medialis muscle and the Vastus lateralis muscle the deepest head deep to rectus femurs its not pretty, it fuses with all of them

Innervation of Tensor fascia latae muscle

cranial gluteal nerve

Action of Rectus femoris muscle

extend the stifle joint flexes the hip joint

Innveration of Quadriceps femoris muscle

femoral nerve
