What is the smallest bone in the human body?
The stapes bone is the smallest bone in the human body. It is located in the middle ear and is one of three tiny bones, known as ossicles, that transmit sound vibrations from the eardrum to the inner ear. The stapes bone is shaped like a stirrup, and its length is only about 3mm in adults.
Despite its small size, the stapes bone is essential for hearing. It is also one of the few bones in the human body that does not have a blood supply. Instead, it receives oxygen and nutrients from the surrounding fluids of the inner ear.
