Describe the pathway of sound from the point where it enters the outer ear to the point in which the sound information travels to the brain. briefly describe the structure and function of each organ along the pathway.

The sound first enters through the auricle (pinna) the part of the ear you can see, then travels through the ear canal. It the reaches the ear drum which is vibrated by the sound waves. The ear drum is also called the tympanic membrane and is a piece of tissue that is tightly stretched. The vibration from the ear drum then moves the ossicles, which are tiny bones in the inner ear called the hammer (malleus), anvil (incus) and stirrup (stapes). The ossicles are attached to the cochlea, which has a snail-like shape and is filled with fluid and lined with tiny hairs. The ossicle movement move the fluid in the cochlea which stimulates the tiny hairs. Then the information is transferred to the brain

Explanation:

Meiosis reproduces cells, so if you get a cut somewhere, Meiosis will help reproduce the same cell, so the species can continue living. Meiosis also gives us immunity to some diseases.
