The ear ossicles transmit sound waves to:
1. Ear drum | 2. Oval window |
3. Round window | 4. Cochlear duct |
The auditory tube [also called as the Eustachian tube] functions in equalizing pressure between the middle ear and:
1. throat | 2. inner ear |
3. outer ear | 4. cochlea |
The tympanic membrane:
1. is covered on both sides by skin
2. is covered on both sides by mucus membrane
3. is covered with skin on the outside and by mucus membrane on the inside
4. is covered with skin on the inside and by mucus membrane on the outside
