Cochlea to structures in the brainstem for further processing. The "stapes" (stirrup) ossicle bone of the middle ear transmits vibrations to the "fenestra ovalis" (oval window) on the outside of the cochlea, which vibrates the perilymph in the "vestibular duct" (upper chamber of the cochlea). The ossicles are essential for efficient coupling of sound waves into the cochlea, since the cochlea environment is a fluid–membrane system, and it takes more pressure to move sound through fluid–membrane waves than it does through air; a pressure increase is achieved by the area ratio of the tympanic membrane to the oval window, resulting in
Where the Sidewalk Ends (poem) the children because they know the place where the sidewalk ends. Looking more in depth at this poem makes clear what Shel Silverstein is saying. Do what the children do. They know the place where the sidewalk ends. And in doing so, you will find the joy and passion for life that they have.
