What are the main actions of the vasti muscles?
Knee extension
What is the lateral border, medial border, and superior border of the femoral triangle?
- Lat = Sartorius
- Med = Adductor longus
- Sup = Inguinal ligament
How does the sartorius muscle pass the knee joint to attach to the tibia?
- distally and medially
- pases posteriorly
What is the quadriceps tendon attached to?
The tibial tuberosity
What is the function of the tensor fascia lata?
To tense the fascia lata
which provides lateral support to the knees
as the knee extends
What muscle is this?
Vastus medialis
True or false?
The rectus femoris attaches to the tibial tuberosity
False
The rectus femoris blends with the other quadriceps muscle to form the quadriceps tendon which attaches to the tibial tuberosity
What is this muscle called?
