Today i am going to teach on the topic : The Human ear
The outer part of the Human ear is located at the both sides of the head
Ear helps us to hear sounds around us .
The Pinna a flap of skin and cartilage collect sound waves and funnel them into the ear canal
Structure of human ear
The Auditory ossicles are small bones that carry the vibrations from the eardrum to the cochlea. they amplify the vibrations . these bones are called the hammer, the anvil , and the stirrup .
Ear canal is the tube that connects the pinna to the Ear drum
sound waves that travel through the ear canal makes ear drum to vibrate
The ear drum is the soft membrane that seperates the inner ear and outer ear
The cochlea is a spirat shaped chamber that is filled with liquid and lined with hairs . it converts the vibrations into electrical signals .
The Auditory nerve connects the cochlea to the brain . it caries the electric signals to the brain
sir, as our ears plays an imprtant role.... but what if someone loses his earing abilities
A Hearing aid is a device used to help people whose hearing power is loss . hearing aids can fit on or in the ear so that it will amplifies sound using electronics
For this we have hearing aids.....
