Vastus Lateralis and Vastus Medialis
Vastus Medialis The vastus medialis is posterior to the rectus femoris, on the inside, or medial, portion of the hind leg. In the picture to the left, the vastus medialis is being lifted up by the blunt probe. How-To: To find the separation, look for a line that indicates a separation of two muscles and then use the blunt probe it dig around and separate the rectus femoris and vastus medialis. Hint- this is to the left of the adductor magnus and the sartorius.

Vastus Lateralis How-To: The vastus lateralis is on the lateral side of the hind leg. It can only be seen by lifting or cutting the tensor fasciae latae. This is the muscle in between the rectus femoris and biceps femoris. There is a clear line seperating it from the rectus femoris. In this photo, the biceps femoris is being lifted away so we can get a look at the vastus lateralis on the inside.
