    So, do you hear the soft, melodious tones in my voice? Do you know that I’m sitting in front of you? Can you tell that I’m a male? Can you tell that I’m extremely happy right now?

Quite clear, quite obvious. The outer ear and some of the stuff that, you know, you might kind of see if you peek in. It’s stuff that when you go to the doctor, they take a peek, that’s what they’re looking at. They’re looking at the canal. They’re looking at the eardrum or the tympanic membrane. It’s also where you sometimes want to put a Q-tip but not too far. Then we have the middle ear. This includes the three small bones that we all hear about, the three smallest bones in the human body. So the ossicles, the ossicles: the malleus, the incus, the stapes, so we’ve heard this being termed as the hammer, the anvil and the stirrup. And they’re given those names based on their structure.
