middle ear
In your ear, it is the smallest muscle in the human body, it stabilizes the smallest bone in your body the 'Stapes.'
The stapedius muscle gets its name from the bone that it is attached to called the stapes. It means stirrup. It is located in the middle ear.
Stapedius
the smallest muscle is the stapedius inside the ear . the biggest muscles are the external obliques which run from the middle of the back and around the stomach.
the stapedius muscle inside the ear
The Stapedius. Although the experts don't agree on how many muscles there are in the human body, they do agree that the smallest muscle is the stapedius. Located in the middle ear, the stapedius is a mere 1.27 millimetres long. And what does such a miniscule muscle do? It controls the tiniest bone in the body, the stapes or stirrup bone. The stapes and two other bones conduct sound vibrations through the middle ear. Ref: http://en.wikipedia.org/wiki/Stapedius
A small muscle in the ear named Stapedius
The tensor tympani and stapedius muscles in the middle ear are responsible for dampening loud sounds. The tensor tympani contracts in response to loud noises to reduce the vibration of the ear drum, while the stapedius muscle tenses to reduce the movement of the stapes bone, helping to protect the inner ear from damage.
The shortest muscle in the human body is the stapedius muscle, and the muscle with the longest name is the tensor veli palatini muscle. The stapedius muscle is located in the middle ear and helps to stabilize the smallest bone in the body, the stapes. The tensor veli palatini muscle is involved in the function of the soft palate in the mouth.
The stapedius muscle is attached to the stapes. It is the smallest striated muscle in the human body.
The smallest tendon in the body is the stapedius tendon, which is located in the middle ear. The stapedius muscle is the smallest skeletal muscle in the human body, and its tendon attaches to the stapes bone in the middle ear. This tiny muscle and tendon play a crucial role in dampening excessive vibrations of the stapes bone to protect the delicate structures of the inner ear from loud sounds.
Individual cells could be considered smallest whole functional parts. However if you wish to be pedantic you could include the constituents of those cells all the way down to subatomic particles.
Your ear may be rumbling due to a muscle spasm in the middle ear called tensor tympani or stapedius muscle. This can happen in response to loud noises, stress, or changes in pressure.
