Sartorius muscle
Musculus sartorius
Definition
Origin: It differs between species. In equines and ruminants it is located on the fascia iliaca, near the tendon of the psoas minor muscle. In the dog, the sartorius muscle is clearly divided into two distinct bands. The cranial part of the sartorius muscle originates from the ventrocranial iliac spine and the caudal part of the sartorius muscle originates from the iliac crest, between the two cranial spines of the ilium.
Insertion: On the medial side of the tibia, on the fascia iliaca, and on the medial edge of the tibial crest. In carnivores, the cranial part of the sartorius muscle additionally ends at the cranial side and medial edge of the patella.
Action: Flexes the hip and stifle when projecting the limb and contributes to the extension of the stifle when standing.
Nerve: Saphenous nerve.
