Explore the detailed histology of tendons and entheses in this 17-minute educational video by Sam Webster. Learn about the composition of tendons, which primarily consist of type I collagen functioning like ropes to transmit tensile forces generated by muscles, along with elastin for elasticity and proteoglycans. Discover how tendon fibroblasts (tenocytes) maintain this extracellular matrix. Understand the formation of fibrocartilage with type II collagen and chondrocytes at compression points where tendons meet bone. Examine the enthesis—the critical junction where tendon attaches to bone—and observe how calcification is managed at the tidemark. The video features background music "Disco 93" by Gregory David.
