The smallest bone in the body is the stapes. It is one of three tiny bones in the ear that helps people hear. Few people know about the stapes and even fewer people have ever seen one. However, it is an important bone in the human body. If you have problems with your stapes, you have problems hearing. (Identification) The smallest bone in the human body is just 3.3mm long in the average person. The stapes is a tiny stirrup-shaped bone inside the middle ear. In fact, the stapes is also called the "stirrup." It is also the lightest bone in the body. The stapes is one of three small bones, which make up the auditory ossicles that help people hear. (Types) The stapes works together with the second and third smallest bones in the human body. They are the malleus, known as the "hammer," and the incus, known as the "anvil." These are the other two auditory ossicles. All three are needed to transmit sounds from the air to the cochlea. These are chambers of fluid that interpret the sounds that we hear (Effects) The stapes is vital to our ability to hear. Sound waves enter the ear and hit the eardrum. As the eardrum vibrates from the sound, it shakes the malleus, then the incus, then the stapes in the middle ear. The smallest bone in the body then vibrates the fluid in the cochlea at the entrance of the inner ear. (Features) The stapes and other tiny bones in the auditory ossicles of the middle ear are controlled by tiny muscles. These tighten and loosen depending on the sound conditions. When sounds are soft, the muscles relax so the auditory ossicles can vibrate more and sounds are amplified. When there are sudden loud noises, the muscles tighten so the auditory ossicles vibrate less. This is believed to be an instinctive self-defense response to prevent damage to hearing. Humans seem to tighten and loosen the muscles around the auditory ossicles without being aware that they are doing so. (Warning) Any damage to the smallest bone in the body will affect hearing. A condition called "otosclerosis" affects about 1 percent of the population. Patients with otosclerosis have growths on their stapes bones. Sometimes they fuse to other bones of the auditory ossicles or the cochlea. If this happens, the stapes can not vibrate correctly and transfer sounds to the inner ear. There will be moderate to severe loss of hearing. Symptoms of otosclerosis include ringing of the ears, disorientation and problems with balance. Hearing aids can help deal with the hearing loss. In severe cases, surgery is required.

The smallest is the stirrup bone in the ear which can measure 1/10 of an inch. The largest bone, the femur, is found in your thigh.

In the case of workaholics this must be the lazy bone.As it wouldn`t exist would it?
If it had no size,it would be smaller than the anvil bone in the ear,
It would also be smaller than the hammer bone,and the stirrup
bone,ALL three are very small bones,which are important to
HEAR THIS. I still don`t know which is the smallest,but it`s got to be one of these three or even two of these six,assuming you have 2 ears.

I just wanted to set one thing straight:
There is indeed a bone in the penis in many species. Many primates have one and if I remember correctly, it's indeed quite small. BUT HUMANS DO NOT HAVE A PENIS BONE!
