Johannes Kepler was the one who elucidated the 3 laws of planetary orbits, the chief one being the elliptical orbits of the planets around the sun with the sun at a focal point at one end of the orbits. This was derived especially from careful observations by Tycho Brahe of the heavens and based on his model of the orbits so was scientifically based.
Answer:
<h2>Ear has three main parts; outer most part is called outer ear, middle one is as middle ear and innermost as inner ear.
</h2>
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.
