YOUR EARS : Sound comes into the inner ear as vibrations and enters the cochlea
Ear canal
The stirrup bone, also known as the stapes bone, is located in the middle ear. It is one of the three small bones called ossicles that transmit sound vibrations from the eardrum to the inner ear. The stapes bone plays a crucial role in the process of hearing by amplifying sound waves.
The cochlea is located at the end of the ear canal - inside the ear. It contains fluid and microscopic hairs (cilia). Sound waves received by the ear causes movement of the cilia - which is interpreted by the brain.
I dont know if you're referring to the hammer as in the ear. Also called the malleus. "The middle ear, an air-filled cavity behind the ear drum (tympanic membrane), includes the three ear bones or ossicles: the malleus (or hammer), incus (or anvil), and stapes (or stirrup)." http://en.wikipedia.org/wiki/Ear
The three smallest bones in the human body are the auditory ossicles found in the middle ear - they are the malleus, stapes, and incus. More commonly known as the hammer, stirrup, and anvil.
Your cochlea is located in the inner ear, specifically within the bony labyrinth. It is a spiral-shaped, fluid-filled structure responsible for converting sound vibrations into electrical signals that can be interpreted by the brain.
The smallest bone in the body is in your ear and is called the stirrup bone (stapes). It is only 0.25 to 0.33 cm long (0.10 to 0.13 in) and weighs only 1.98 to 4.3 mg.
