Overview
In the horse it arises inside the abdominal cavity, from the iliac fascia, and runs down the medial thigh to the stifle. Its caudal border and the cranial border of the gracilis bound the femoral triangle, through which run the femoral artery and vein and the saphenous nerve.
Origin
Iliac fascia and tendon of the psoas minor.
Insertion
Medial patellar ligament and medial surface of the proximal tibia, through the fascia, together with the gracilis.
Action
Flexes the hip and adducts the pelvic limb.
Innervation
Femoral nerve (n. femoralis), through the saphenous nerve.
