What is the hammer part of ear?

The hammer is one of the three small bones in the middle ear, also known as the malleus. It is shaped like a hammer, with a head, neck, and handle. The head of the hammer connects to the eardrum, while the neck and handle connect to the anvil and stirrup, the other two small bones in the middle ear.

The hammer's main function is to transmit sound vibrations from the eardrum to the anvil and stirrup. When sound waves hit the eardrum, it causes the eardrum to vibrate. These vibrations are then transmitted to the hammer, which in turn transmits them to the anvil and stirrup. The anvil and stirrup then amplify the sound vibrations and transmit them to the inner ear, where they are converted into electrical signals that are sent to the brain.
