The term AUDITORY RECEPTOR can be summarized as the EAR, which is a three letter word. The EAR is an organ of the body that is responsible for hearing and balance. It is composed of three parts: the outer EAR, the middle EAR, and the inner EAR. The outer EAR collects sound waves and directs them to the eardrum. The middle EAR amplifies the sound and transmits it to the inner EAR. The inner EAR contains the auditory receptor, which converts the sound into nerve impulses that are sent to the brain.
