Abstract

Seventy semitendinosus muscles from cadavers were obtained using standard dissection techniques (50 muscles were obtained from adults, and 20 from fetuses). Moreover, ultrasound examinations of 20 muscles were performed in living individuals. Two main parts of the distal tendon were distinguished - the external part not covered with muscle fibres and the internal part, which is partially or entirely hidden within the muscle belly (venter). The average length of the distal tendon was 32.34 cm, while the average lengths of the external and internal parts were 9.65 cm and 12.59 cm respectively. The external part was solid and cylindrical. The internal part was flat and rolled like a trough, thus making the tendon a poor transplant material. Similarly, the distal tendon in fetuses consisted of two parts, including the external and internal part. The proportions between the lengths of different muscle parts were very similar in adults and fetuses.
