Take a quiz online and post the link.

America in 1915 - I scored 8 out of 10. Beat that.

9 out of 10 in Body Science Part 3
And the one I got wrong was because I was given the wrong info at school. Thanks, Mrs Roland-Davies!

Ah, then again, the nine I got right were thanks to her too! (Basic high school biology quiz)

I might not have done well on the questions they asked, but I can sure as heck spell better than them.

Largelye, indeed.

6 out of 10

You should include a link so that others can try it. Body Science part III

I got 9 out of 10. I must have been sitting behind you in Mrs Roland-Davies class.;)

Sorry, I closed it before I even thought
(my wrong question was re the appendix, if yours was too then perhaps you were in my class!)

Actually, it was.:p

I duffed the Eustachian tube. figured it helped hearing rather than balance, I always thought that was an inner ear thing.

Well there you go - teaching on the appendix has obviously changed.
Perhaps there was an appendix conspiracy back then.

Well, I'm not sure I buy the whole "It may have a use that we just don't know about" theory.

I had my appendix out when I was an infant. I seem to have done ok without it. Except that I'm more liberal.

Maybe that's it. Maybe having an appendix or a larger appendix makes you more conservative.

Naah, looking at Hannity and Limbaugh I'm pretty sure it has more to do with having a bigger asshole.;)

I still have my appendix.
I shudder to think what I'd advocated it that conservative organ was removed!

10 out of 10 on the body quiz. Only got 7 of 10 on the 1915 quiz.

Holy crap, could they make the font any smaller!

Correct. The Eustachian tube has nothing to do with balance. Balance is maintained by many things in the body interacting together, but concerning the ear, it is the vestibular system which maintains balance:

Input from the vestibular system
The inner ear or labyrinth is a complex series of passageways and chambers within the bony skull. Within these passageways are tubes and sacs filled with a fluid called endolymph. Around the outside of the tubes and sacs is a different fluid—the perilymph. Both of these fluids are of precise chemical compositions, and they are different. The mechanism in your inner ear that regulates the amount and composition of these fluids is important to the proper functioning of your inner ear.

Each inner ear has a hearing (auditory) component—the cochlea, and a balance (vestibular) component—the vestibular apparatus, consisting of three semicircular canals and a utricle and saccule. Each of the semicircular canals is located in a different plane in space. They are located at right angles to each other and to those on the opposite side of the head. At the base of each canal is a swelling (ampulla) and within these ampullae are located the sensory receptors for each canal.

Inside each fluid-filled semicircular canal is a sensory receptor (cupula) attached at its base. With head movement in the direction in which this canal is located, the endolymphatic fluid within the canal, because of inertia, lags behind. When this fluid lags behind, the sensory receptor within that canal is bent. The receptor then sends impulses to the brain about movement.

When the vestibular apparatus on both sides of the head are functioning properly, they send symmetrical impulses to the brain. That is, the impulses coming from the right side conform to [agree with] the impulses coming from the left side.

The eustachian tube has three functions: ventilation, drainage, and protection. When the eustachian tube is patent it allows ventilation of the middle ear and equalization of middle ear and atmospheric pressure. It also allows the middle ear to clear unwanted secretions. By staying physiologically obstructed, it protects the middle ear from nasopharyngeal secretions and sound.
