Question

Discuss the functions of human ear.

Answer 1

Human ear:

1. The ear is a sensitive organ of the human body, which employs itself in detecting, transmitting and transducing of the sound.
2. It maintains even the sense of balance.

The function of human ear are as follows:

1. The sound waves pass through the auditory canal and reach the eardrum.
2. The vibrations produced pass through the tympanic membrane to the tympanic cavity.
3. The ear ossicles in the tympanic cavity receive the vibrations and the stapes pushes the oval window in and out.
4. This action is passed on to the organ of corti, the receptor of hearing, that contains tiny hair cells that translate the vibrations into an electrical impulse that are transmitted to the brain by sensory nerves.
5. The eustachian tube equalizes the air pressure in the middle ear and maintains the balance.
6. The vestibular complex contains receptors that maintain body balance.
