The parotid gland
Pretty big gland...No?
It is. It helps with salivation. The jawbone protects most of it. You can however get the edge of it, just behind the ear.
I never took human anatomy so I can't tell you which nerves are also in that same location. But they exist. When I get a chance, I'll do my homework on it.

Umm... Am I being set up with a question like that?

As to the neck strikes…when I gently contact my slightly bent arm and point of elbow against the entire side of the neck, I get 'stoppage reactions' no matter where it lands as I teach it as a pre-emptive move catching them as they come in so their momentum works against them.
I try to be careful not to hit the wind pipe.
As they say, great minds think alike.
We both train the same choreography. And then when we do what we do, we pick things up without understanding where or how we got it. I learned this technique with my Ridgeback. He's a wonderful, wonderful beast. But he has this annoying habit of compulsively engaging in "flying kisses." Having a large dog leap in the air and kiss you is cool... until he goofs a bit. One day he almost took my two front teeth out. Now I have to do my best to discourage the habit.
I employ this exact same technique, Van. A very large dog is lunging at my face, and I do a shearing motion of the forearm across the side of the neck. When he's in a "repeat" mode on this compulsive behavior, I'll sometimes finish the shearing motion with a circle whereby I'm able to pin him down on the ground so he won't leap again. Understand that Maverick is a beast, and a normal choke collar barely registers on his neck. This isn't about hurting him as much as it is about controlling him with excellent mechanics.
Now if you shear across the carotid, well that's what I mean by "poison on the end of the spear." Maybe you get the effect and maybe you don't. Worst case scenario is you execute a sound technique that mechanically stops someone in their tracks. The neck provides a very long lever arm away from the center of gravity, so it's easier to unbalance someone. The voodoo (carotid strike blackouts) is icing on the cake when it works. But even a small vasovagal response adds caffeine to sound mechanics.

Also a fainting response can be achieved by digging your thumb and index finger around both sides of the neck at the C. Synus points. Correct?
In general, no. There are rare cases written up in the medical literature. But for the most part, carotid massage is used to lower heart-rate and blood pressure. With most normal people, you can't make them black out with a "digging" motion at the carotid sinuses. A thrusting motion improves the odds. In other words, dL/dt of the tissue in the carotid sinus provides a greater response than delta L (if that makes sense).
Even if you completely block the blood flow in both carotids, you can't make someone black out. The paravertebral arteries also supply the Circle of Willis in the brain, so brain blood flow is still adequate for consciousness. The "blood choke" techniques instead work by crimping the jugular veins, thereby blocking venous return from the brain. No blood out means no blood in.
