Muscle architecture for pennate muscles. Pennate muscles can be further divided into uni-, bi- or multipennate. Unipennate muscles are those where the muscle fibers are oriented at one fiber angle to the force-generating axis and are all on the same side of a tendon. The pennation angle in unipennate muscles has been measured at a variety of resting length and typically varies from 0° to 30°. The lateral gastrocnemius of wild turkeys is an example of this muscle architecture. Muscles that have fibers on two sides of a tendon are considered bipennate. The stapedius in the middle ear of humans, as well
Bartholomew the Apostle also came to be associated with salt, oil, and cheese merchants. Although Bartholomew's death is commonly depicted in artworks of a religious nature, his story has also been used to represent anatomical depictions of the human body devoid of flesh. An example of this can be seen in Marco d'Agrate's "St Bartholomew Flayed" (1562) where Bartholomew is depicted wrapped in his own skin with every muscle, vein and tendon clearly visible, acting as a clear description of the muscles and structure of the human body. The Martyrdom of Saint Bartholomew (1634) by Jusepe de Ribera depicts Bartholomew's final moments before
