Sesamoid bones are bony protrusions or nodules that develop in tendons and are attached to ligaments. They are essential for creating stable environments so the body can carry out specific tasks. Sesamoids act like biological pulleys, allowing muscles to flex and extend in different directions.

You can think of orthopedists as bone doctors. Some of the conditions you can see them for are scoliosis, scapula, and kyphosis. Many of these conditions result in poor posture and abnormal growth. Humans, unlike most other mammals, have an erect posture.
