What’s the smallest muscle in the human body?
The stapedius, in your middle ear, measures about 1mm in size (or
1/26 of an inch). Connected to the stapes bone, it contracts to pull
back the stapes and help protect your inner ear from loud noises. The
stapedius also contracts to keep your own voice from sounding too loud
in your head.
What’s the smallest bone in the human body?
Conveniently, that would be the stapes. It is one of three tiny bones
in the middle ear that convey sound from the outer ear to the inner
ear. Collectively called the ossicles, these bones are individually
known as the malleus, incus, and stapes. Those are Latin words for the
shapes the bones resemble: a hammer, anvil, and stirrup.
What’s the smallest organ in the human body?
You’ll find the pineal gland near the center of the brain, in a
groove between the hemispheres. It’s not an organ like those in the
abdominal cavity. It’s the human body’s smallest endocrine gland, and it
produces melatonin, a hormone (derived from serotonin) that affects how
we sleep, wake up, and react to seasonal changes. It’s called pineal
because it’s shaped like a little pinecone.
What’s the smallest blood vessel in the human body?
<span>Capillaries, the smallest, thinnest-walled blood vessels in the body,
connect veins and arteries. They can be as small as 5-10 micrometers
wide — or 50 times thinner than a baby’s hair. Each of us contains about
10 billion of them, with the average adult body containing about 25,000
miles of capillaries.</span>
