I. Deep to Sartorius

Superior to Inferior AND Lateral to Medial:
1. vastus lateralis:

vastus lateralis is "lateral" to rectus femoris.

2. rectus femoris:

rectus femoris is like the "hot dog" between the 2 "buns" vastus medialis and vastus lateralis (underneath tensor fascia lata).

3. vastus medialis:

vastus medialis is "medial" relative to rectus femoris.

II. Deep to Gracilis

Superior to Inferior:
1. pectineus:
Note: Even this BIG cat has a super-tiny pectineus (immediately next to the blue vein).

2. adductor longus: 

3. adductor femoris:

Note: Adductor femoris is in 2 parts as shown above by the probes.
