Sesamoid bone: S are small

Sesamoid bones are small, round bones embedded within tendons, most commonly found in locations where a tendon passes over a joint, such as in the hands, feet, and knees. Their primary function is to protect tendons from stress and wear, and the largest sesamoid bone in the human body is the patella, or kneecap. Understanding sesamoid bones helps in recognizing their role in improving the mechanical leverage of tendons, a crucial aspect in efficient joint movement and function. Sesamoid bones are small, usually less than one centimeter in size. They are round or oval in shape and are composed of spongy bone surrounded by a thin layer of cortical bone. They have a smooth surface and are surrounded by a thin layer of connective tissue called the periosteum. Discover sesamoid bones, their role in movement, key examples like the patella and pisiform, and how they enhance stability and prevent injuries. What exactly is Seasomoid Bone? A Sesamoid bone is a bone that is implanted within a tendon or muscle. Its name comes from the Greek word for “sesame seed,” referring to the microscopic size of most sesamoids. These bones frequently develop in reaction to tension or as a natural variety. The patella is the body’s biggest sesamoid bone. Sesamoids function similarly to pulleys, providing a smooth surface for tendons to glide over, enhancing the tendon’s capacity to transfer muscle ...
