One of the mysteries of the English language finally explained.
A long, narrow muscle running obliquely across the front of each thigh from the hipbone to the inside of the leg below the knee.
- ‘The superficial branch supplies sensory innervation to the skin of the anterior thigh and motor innervation to the sartorius muscle.’
- ‘Of the anterior group of muscles, those seen at this level include the sartorius and quadriceps femoris.’

- ‘The anserine bursa is a fairly large bursa that ties behind the tendons of sartorius, gracilis, and semitendinous muscles and the tibial collateral ligament.’
- ‘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.’
