Distinguish between the major anatomical components of the outer, middle, and inner ear. Then trace the route of a sound from the external environment to the transducers in the inner ear.

Explanation:

1. Outer Ear: Pinna (the outer, funnel-like part), Ear Canal (Conducts sound vibrations from the pinna to the tympanic membrane), and Tympanic Membrane.

2. Middle Ear:  Ossicles (Tiny bones that amplify sound waves), Malleus, Tensor Tympani, Incus (Connects the Malleus to the Stapes; receives vibrations from the Malleus and looks like an anvil), Stapes, Stapedius, Oval Window (Receives vibrations from the Stapes and is the flexible opening to the cochlea).

3. Inner Ear:  Cochlea (The main structure in the inner ear; tiny coiled structure); Tympanic Canal, Vestibular Canal, Basilar Membrane, Cochlear Partition , Round Window  Organ of Corti.

.

Route of Sounds: External environment →  Collected by the pinna → Through the ear canal →  Vibrates the Tympanic Membrane →  Vibrates the ossicles →  Vibrates the Oval Window →  Sends “Traveling Waves” through the Vestibular Canal →  Pressure released by Round Window if necessary →  Inner and Outer hair cells transduce the vibrations.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
