This photomicrograph features the myotendinous junction, a region located at the muscle-tendon interface, which is essential for transmitting force between muscle and tendon. At this junction in humans, the sarcolemma invaginations form finger-like structures, which significantly increase the contact area between muscle and tendon. This image shows a piece of human muscle that was harvested and processed for transmission electron microscopy.
