This is an image of a human ear, with the left side of the ear visible, and the right side of the ear occluded. The ear is the external ear, which is composed of the pinna, the auricular, and the helix. The pinna is the outer flap of skin that forms the external part of the ear. The auricular is the cartilage that forms the part of the ear that is connected to the skull. The helix is the curved part of the ear that is visible when the ear is turned to the side. The ear is an important part of the human body, as it is responsible for hearing and providing balance. It is also responsible for regulating the body's temperature, which helps to prevent overheating. The ear contains three main parts: the outer ear, the middle ear, and the inner ear. The outer ear is the part of the ear that is visible, and it is responsible for capturing sound waves and transmitting them to the middle ear. The middle ear is responsible for amplifying the sound waves that are captured by the outer ear, and it contains three small bones called ossicles. The inner ear is the part of the ear that is responsible for converting sound waves into electrical signals that are sent to the brain. It contains the cochlea and the vestibular, which are responsible for hearing and balance, respectively.
