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
