Function of the Human Ear
The human ear’s various structures aid in various purposes.
- The eardrum is protected by the pinna of the outer ear, which transports sound to the eardrum through the auditory canal.
- When the eardrum vibrates, sound is transmitted to the inner ear.
- The middle ear’s ossicles enhance sound and transmit vibrations to the oval window. The membrane that separates the inner and middle ear is known as the oval window.
- The Eustachian tube is a thin tube that links our nose to our ear. This tube aids in the passage of air into the lungs and discharges mucus to the nasopharynx.
- The cochlea is a structure found in the inner ear. It is filled with fluid and houses the Corti organ. Cortis organ has cilia, which are hair-like sensory cells. Waves from the middle of the year generate vibrations in the inner ear fluid, which causes the cilia to vibrate. The cilia vibrates, sending nerve signals to the brain.
- The semicircular canals in the inner ear are vertically aligned with one another. It also has fluid in it, which aids in mobility.
Human Ear
It has been discovered that sound is a type of energy. Vibrations cause it to happen. Longitudinal waves are sound waves. Because they are elastic waves, they must be transmitted through a material medium. They can move through solids, liquids, and gases. In solids, their velocity is greatest, whereas, in gases, it is lowest.
In our daily lives, we hear a variety of sounds, including pleasant ones known as musical sounds, noise, loud sound, high-pitched sound, and other unpleasant sounds are examples. The majority of mammals on Earth have an external ear. Our auditory system includes the ear. The pinna is the part of the ear that is visible from the outside. Humans, like other mammals, have ears. The temporal bones of the skull house the ears on both sides of the brain. Before discussing the human ear and its range of hearing first we’ll discuss the production of sound and sound waves.
