A human ear dissection model is an invaluable resource for anyone interested in learning about the ear's intricate anatomy. The ear is a complex organ that is responsible for hearing and balance, and understanding its structure can help you understand how it works. A preserved human ear that has been carefully dissected and labeled to highlight its various structures is typically used as the model. The structures visible in a human ear dissection model include the outer ear, middle ear, and inner ear. The visible portion of the ear that collects sound waves and directs them toward the ear canal is known as the outer ear. The ear canal is a narrow, tube-like structure that connects the outer ear to the middle ear via the eardrum. The ossicles are three small bones in the middle ear that transmit sound waves from the eardrum to the inner ear. The cochlea, a snail-shaped structure in the inner ear, converts sound waves into electrical signals that are sent to the brain. The semicircular canals are another structure visible in a human ear dissection model. These canals are part of the inner ear and are in charge of detecting changes in head orientation, which is critical for maintaining balance.
