There is a bone bone in your body that never grows which is the 3 ossicles that are in your middle ear which include the stapes, incus and malleus which do not grow after birth.
The 3 ossicles or incus, stapes and malleus are around 3 mm in size since birth and remain the same size for birth.
The hyoid bone that is located in the neck also does not articulate with any other bone in the body and also doesn't grow and remains a fixed size.
The hyoid bone is also a bone that is a floating bone in the body.
The hyoid bone is a bone that is shaped like a horseshoe and is located in your neck, below your mandible and above your larynx.
Your hyoid bone is not attached to any other bones in the body and is only supported by ligaments and muscles.
You can feel your hyoid bone by placing your fingers where your neck and chin meet and then swallow.
As you swallow and have your fingers between where your chin and neck meet, you can feel the hyoid bone.
The hyoid bone is a special bone because the hyoid bone floats in the body and is not connected to other bones.
Instead your hyoid bone is held in place by muscles, cartilage and ligaments in the body.
The hyoid bone is a crucial and necessary bone for helping with swallowing, speaking and even breathing.
The hyoid bone also serves as an attachment point for several different muscles that are involved in these functions, and also supports the tongue, the floor of the mouth and the larynx.
It's also believed that the hyoid bone also helps to maintain an open airway, most particularly during sleep and may also be implicated in obstructive sleep apnea.
