ear is also known as?

The ear is also known as the auditory system or the hearing organ. It is responsible for detecting sound waves and converting them into electrical signals that are interpreted by the brain. The ear can be divided into three main parts: the outer ear, the middle ear, and the inner ear. The outer ear consists of the auricle (or pinna), which collects sound waves, and the ear canal, which leads to the middle ear. The middle ear contains the eardrum, which vibrates when struck by sound waves, and the three ossicles (malleus, incus, and stapes), which amplify the vibrations and transmit them to the inner ear. The inner ear consists of the cochlea, a spiral-shaped structure that contains fluid and hair cells that convert the vibrations into electrical signals, and the vestibular system, which is responsible for balance.
