Each sense is designed to convert a particular stimulus into the transmission of a nerve impulse. In hearing, what is the original stimulus? _______ Exactly where is the nerve impulse generated? ___________ How can a sore throat and chronic inflammation affect one's ability to hear? ______________ Where are the receptors located that provide information about dynamic equilibrium and balance during change of position? ________________ Which cranial nerve transmits the impulses for balance and equilibrium to the brain?__________

Explanation / Answer

2. In hearing, sound is the original stimulus and it is converted into nerve impulse which is interpreted by brain.

3. Organ of corti present in the Cochlea contain hairy cells with receptors which receives sound and generates nerve impulse

4. Infection also passes to the ear and blocks the passage for stimulus and therefore nerve impulse is not generated or stimulus is not strong enough to generate the nerve impulse.

5. Receptors are present in the semicircular canals and vestibular sacs of the inner ear.
