Base of the Femoral Triangle
Where does the Pectineus Muscle originate from?
Pectineal Line of the Anterior Surface of the Pelvis
Where does the Pectineus Muscle attach distally?
Pectineal Line of the Posterior Surface of the Femur, just inferior to the Lesser Trochanter
What is significant about the innervation of the Pectineus Muscle?
It has dual innervation, so can be considered a transitional muscle between the Anterior and Medial Compartments of the Thigh
What is the innervation of the Pectineus Muscle?
- Femoral Nerve
2. It may also receive a branch from the Obturator Nerve
Where is the Gracilis Muscle located, in relation to the other Muscles of the Medial Compartment of the Thigh?

- Anteriorly - Tendon of the Sartorius Muscle
2. Posteriorly - Tendon of the Semitendinosus Muscle
What Joints does the Gracilis Muscle cross?
- The Hip Joint
2. The Knee Joint
What is the function of the Gracilis Muscle?
- Adduction of the Thigh at the Hip Joint
2. Flexion of the Leg at the Knee Joint
What is the innervation of the Gracilis Muscle?
