Ear Functions and Structure - Lesson 278
In this post, we are going to learn about ear functions and structure . This lesson begins the ear anatomy and physiology lessons. In the future posts, we will learn about human ear anatomy and physiology. As per the passage of sound waves from the ear to the brain, we can divide the ear structure into four divisions, such as outer ear, middle ear, inner ear or labyrinth, and brain. The outer ear consists of pinna, external auditory ear, and tympanic membrane. The middle ear consists of malleus, incus, stapes, and oval window. The inner ear or labyrinth consists of cochlea, auditory liquids and receptors, and auditory nerves. In the brain, the ear is connected with cerebral cortex. We will learn about each of these parts of the ear one by one now. Ear Functions and Structure: Outer Ear: Any sound waves from our surrounding will enter into the outer ear first through the muscle part called pinna or auricle, outside the ear, which projects outside the ...
