The answer to the crossword for the term 'Organ with a Drum in it' is EAR. The EAR is an organ of the human body that is responsible for hearing and balance. It is made up of three parts: the outer EAR, the middle EAR, and the inner EAR. The inner EAR contains a small drum-like structure called the cochlea, which is filled with fluid and lined with tiny hairs that vibrate when sound waves enter the EAR. This vibration is then converted into electrical signals that are sent to the brain, allowing us to hear.
