Question: What is the smallest bone in the human body?
Answer: The stapes is the smallest bone in the human body. It connects the ear to the middle ear and can be found at either side of the eardrum. The function of this small bone is to transmit vibrations from sound waves into nerve impulses, which are then transmitted to the brain.
The diameter of stapes is around 0.5 mm while its length ranges between 5-6mm which makes it one of the shortest bones in our body . There are two important features about this tiny bone that make it so unique among other bones: It has only one canal for both transmission and reception whereas all other bones have two canals (transmission and reception). Also, its length is less than half an inch which makes it among the shortest bones present in our body.
