38THE PASSAGE OF SOUND THROUGH THE OUTER EAR

The [blank_start]auricle[blank_end] directs sound waves towards the [blank_start]external auditory meatus[blank_end]. At the end of the EAM it hits the [blank_start]tympanic[blank_end] membrane. High pitched sounds cause it to vibrate [blank_start]quickly[blank_end]. Low pitched sounds cause it to vibrate [blank_start]slowly[blank_end]. Sound waves are converted to [blank_start]mechanical[blank_end] vibration.
1. Aauricle
2. Bexternal auditory meatus
3. Ctympanic
4. Dquickly
5. Eslowly
6. Fmechanical
39THE PASSAGE OF SOUND THROUGH THE MIDDLE EAR

The [blank_start]auditory ossicles[blank_end] of the middle ear transmit the vibrations to the inner ear. The tympanic membrane attaches to the [blank_start]malleus[blank_end]- the largest auditory ossicles. The [blank_start]incus[blank_end] is the middle ossicle. The [blank_start]stapes[blank_end] is the third ossicle (it is also the smallest bone in the human body). The stapes attaches to the [blank_start]round window[blank_end], which separates the middle and inner ear. The [blank_start]oval window[blank_end] vibrates [blank_start]20[blank_end] times more vigorously than the tympanic membrane because the auditory ossicles transmit the vibrations efficiently.
1. Aauditory ossicles
2. Bmalleus
3. Cincus
4. Dstapes
5. Eround window
6. Fround window
7. G20
40PASSAGE OF SOUND THROUGH THE INNER EAR

Vibrations at the round window causes the movement of perilymph at the [blank_start]cochlea[blank_end]. Pressure waves through the inner ear. The pressure waves cause [blank_start]endolymph[blank_end] within the cochlea duct to move. This causes the [blank_start]stereocilia[blank_end] (hair-cells) to bend which generates nerve [blank_start]impulses[blank_end].
1. Acochlea
2. Bendolymph
3. Cstereocilia
4. Dimpulses
41NERVE IMPULSE PRODUCTION IN THE INNER EAR

When the [blank_start]stereocilia[blank_end] bend it allows endolymph to enter. The endolymph is [blank_start]potassium[blank_end] rich, which causes an energy potential. A neurotransmitter is then released which generates a nerve [blank_start]impulse[blank_end] in sensory neurons of the hair.

The impulse is passed along the [blank_start]vestibulocochlear[blank_end] cranial nerve. From here, it goes to the cochlear nuclei in the medulla oblongata. It then passes to the midbrain and thalamus, eventually reaching the PRIMARY AUDITORY AREA in the temporal lobe of the cerebral cortex.
1. Apotassium
2. Bstereocilia
3. Cimpulse
4. Dvestibulocochlear
