Detailed explanation-1: -Domingo has just hit Play to begin listening to a new song he bought. Based on the structure of the ear, what will the sound waves contact first after moving through Domingo’s auditory canal? A. The cochlea.
Detailed explanation-2: -1. The sound waves arrive at the pinna (auricle), the only visible part of the ear. 2. Once the sound waves have passed the pinna, they move into the auditory canal (external acoustic meatus) before hitting the tympanic membrane (eardrum).
Detailed explanation-3: -Thus, it can be concluded that the correct pathway for the transmission of sound waves from the air into the ear is: the auditory canal-tympanic membrane-ossicles-the organ of Corti.
Detailed explanation-4: -This movement stimulates hair-like receptors, which send messages to the cerebellum at the back of the brain, thus enabling you to sense your body position and to maintain your balance.
Detailed explanation-5: -The retina senses light and creates electrical impulses that are sent through the optic nerve to the brain.
