Quiz - 31 - Diving Knowledge Workbook - Diving Physiology

[Pedro Burrito]

From the Diving Physiology Section of the PADI Diving Knowledge Workbook Version 2.02 © PADI 2009:

Objective 2.13 - Describe the basic anatomy of the ear and which areas/structures are most affected by changing pressures.

Question 1

Sound vibrations are transferred from the outer to the inner ear via the:

a. oval window

b. round window

c. cochlea

d. ossicles​

I will post a daily question from my exams to help newer divers and to encourage more experienced divers to interact gracefully and helpfully with the newer divers.

Reminder - this is a post in the Basic Forum and it is a green zone. Please be nice and on topic.

Thank you for your patience while we try to give people something to discuss other than Covid-19 and/or Politics. I will post the answer covered by the spoiler tag later today.

Spoiler: Answer

d. ossicles

The ossicles are the series of bones that are attached at one end to the tympanic membrane (ear drum) of the outer ear, and are connected to the oval window of the inner ear. The mechanical advantage resulting from the arrangement of the ossicles also amplifies the vibrations as they pass from the outer to the inner ear.
