Question 14

Sound

Answer 14

The reception of sound waves and their perception by the brain

Question 15

The characteristics of sound

Answer 15

Wavelength (measured in m) , Amplitude (dB), Frequency(Hz), Time Period, Velocity

Question 16

Frequency

Answer 16

Known as pitch, The number sound pressure waves per second

Question 17

Amplitude

Answer 17

The relative strength of sound waves, which we perceive as loudness or volume

Question 18

Function and importance of the Pinna

Answer 18

acts as a kind of funnel which assists in directing sound further into the ear

Question 19

Function and importance of the external auditory meatus

Answer 19

Conducts sound to the eardrum and middle ear

Question 20

Function and importance of the tympanic membrane

Answer 20

Transmits sound vibrations to auditory ossicles and oval window

Question 21

Function and importance of the ossicles (malleus, incus, and stapes)

Answer 21

Transmit vibrations to the inner ear and help amplify sound

Question 22

Function and importance of the cochlea

Answer 22

Contains hearing receptors, detects low frequency sounds

Question 23

Function and importance of the organ of Corti

Answer 23

Transforms vibration into a nerve impulse that can be interpreted by the brain

Question 24

Function and importance of hair cells

Answer 24

Produces nerve impulses that are sent to the brain via the cochlear nerve

Question 25

Function and importance of the vestibulocochlear cranial nerve
(In hearing)

Answer 25

It brings in sound via the cochlear nerve to the brain

Question 26

What is the physiology of sound transduction?

Answer 26

SW’s enter —> TM vibrates—-> Perilymph in BL and endolymph in ML move —– BM vibrates —–> Hair cells in OOfC are stimulated to transmit n. impulse via cochlear n. —–> N. Impulses are sent to the brain
