A long, narrow muscle running obliquely across the front of each thigh from the hip bone to the inside of the leg below the knee.‘It passes between the dorsal border of the sartorius and the anterior border of the tendon of gracilis.’
- ‘The superficial branch supplies sensory innervation to the skin of the anterior thigh and motor innervation to the sartorius muscle.’
- ‘The anserine bursa is a fairly large bursa that ties behind the tendons of sartorius, gracilis, and semitendinous muscles and the tibial collateral ligament.’
- ‘Of the anterior group of muscles, those seen at this level include the sartorius and quadriceps femoris.’
- ‘Pain on the back of the medial of our knees may be caused by friction of three muscles rubbing together - your sartorius, gracilis and semitendinosus.’
Early 18th century modern Latin, from Latin sartor ‘tailor’ (because the muscle is used when adopting a cross-legged position, earlier associated with a tailor's sewing posture).
