Do your ears have bones in them?

Question

My friend says they have (3), but I say they are all cartlidge and have none.

Answer 1

The outer ear (pinna) has no bones, but is made up of cartilage.
Your friend is right too, the inner ear is the bony labyrinth, a system of passages comprising two main functional parts: the organ of hearing, or cochlea and the vestibular apparatus, the organ of balance that consists of three semicircular canals and the vestibule. Inner ears are found in all vertebrates, with substantial variations in the form and function of their sensory organs. Each animal has two inner ears, one on each side of its head.

In mammals, the outer ear focuses and directs sound waves into the middle ear. In the middle ear, the energy of these pressure waves[1] is translated into mechanical vibrations of the middle ear s bone structure. The cochlea of the inner ear propagates these mechanical signals as waves in fluid and membranes, and finally transduces them to nerve impulses which are transmitted to the brain.

The vestibular system of the inner ear is responsible for the sensations of balance and motion. It uses the same kinds of fluids and detection cells (hair cells) as the cochlea uses, and sends information to the brain about the attitude, rotation, and linear motion of the head. The type of motion or attitude detected by a hair cell depends on its associated mechanical structures, such as the curved tube of a semicircular canal or the calcium carbonate crystals (otolith) of the saccule and utricle.

The inner ear is innervated by the eighth cranial nerve in all vertebrates.

If your jaw bone has come out of its socket, it will not be possible for you to open the mouth more than an inch. The movements of the jaw will be ackward and one sided. Tongue would also find difficulty in movement. It has to be checked by a Dental Surgeon and an experienced Dental Surgeon can normally put it back into the socket without any further damage. In your case from the description it does not seem to have dislocated. Do not do anything yourself forcefully. Have it checked from a Dental Surgeon. Light massage using one finger and writing the letter "8" on the portion just below the ear where jaw starts would give a soothing effect.

Answer 3

The middle ear contains three tiny bones known as the ossicles: malleus, incus, and stapes. The ossicles were given their Latin names for their distinctive shapes; they are also referred to as the hammer, anvil, and stirrup, respectively. The ossicles directly couple sound energy from the ear drum to the oval window of the cochlea. While the stapes is present in all tetrapods, the malleus and incus evolved from lower and upper jaw bones present reptiles.

Answer 4

The exterior portion of your ear has no bone, it is cartilage, but inside you ear are three bones that are used to assist you in hearing -- they are the hammer, stirrup and cochlea. they are located in the inner ear behind the ear drum.

Answer 6

the inner ear has 3 tiny bones in it called: the stirrup, anvil and hammer. and once a sound causes the eardrum to vibrate these tiny bones vibrate transmitting the sound waves to the cochlea and the auditory nerve to the brain. and thus we hear a sound

Answer 7

we do in fact have bones in are ear

Answer 8

I would talk to your doctor. You may need surgery or the doctor may need to put it back. I've had to it happen before and it is nothing like putting a shoulder back in its place. It doesn't hurt at all, trust me. Just go see your doctor.
