Description:-

The human ear is an important sense organ that helps us hear sounds and maintain balance. It is divided into three main parts—the Outer Ear, Middle Ear, and Inner Ear. Each part has a special function that helps us understand the world through sound.

Parts of the Human Ear & Their Functions

🔹 1. Outer Ear

Parts:

Pinna (Auricle)

Ear Canal (Auditory Canal)


Functions:

Collects sound waves from the surroundings

Directs sound into the ear canal toward the eardrum


🔹 2. Middle Ear

Parts:

Eardrum (Tympanic Membrane)

Ossicles (Hammer, Anvil, Stirrup)

Eustachian Tube


Functions:

Eardrum vibrates when sound hits it

Ossicles amplify the sound vibrations

Eustachian tube maintains air pressure inside the ear

🔹 3. Inner Ear

Parts:

Cochlea

Semicircular Canals

Auditory Nerve


Functions:

Cochlea changes vibrations into electrical signals

Auditory nerve carries sound signals to the brain

Semicircular canals help maintain balance.
