Verified step by step guidance

Identify the components of the ear: The ear is divided into three main parts - the outer ear, the middle ear, and the inner ear.

Understand the function of the outer ear: The outer ear consists of the pinna and the ear canal, which collect sound waves and direct them towards the middle ear.

Recognize the role of the tympanic membrane: The tympanic membrane, also known as the eardrum, is a thin membrane that separates the outer ear from the middle ear.

Explain the function of the tympanic membrane: When sound waves reach the tympanic membrane, they cause it to vibrate. These vibrations are then transmitted to the bones of the middle ear.

Conclude that the tympanic membrane acts as the gateway: Since the tympanic membrane is the structure that receives sound waves from the outer ear and transmits them to the middle ear, it serves as the gateway between these two parts of the ear.
