The function of the eardrum in the middle ear is to vibrate with the frequency of the received sound.
Further Explanation:
Ear is the sensory organ of many organisms which performs the function of hearing.
Structurally it can be divided into three basic parts:
1. Outer ear
2. Middle ear
3. Inner ear
<u>Outer ear</u> consist of <u>pinna</u> and <u>ear canal</u>. Pinna is made up of tough cartilage which is covered by skin. The main function of the pinna is to gather sounds and to move them to the ear canal. Eardrum serves as the pathway that leads to the middle ear.
<u>Middle ear</u> consists of eardrum that separates them from the outer ear. When sound waves hits the <u>eardrum</u>, it vibrates with the frequency of the received sound.
The <u>inner ear</u> changes the vibrations coming from the middle ear to the nerve signals. The inner ear consist of cochlear and semicircular canal.
The cochlea changes the <u>vibrational signal into nerve signals</u> that travels to the brain through the auditory nerve. The function of semicircular canal is to maintain the body balance.
