I am researching a problem my friend has. Anytime she drinks water she feels nauseous.

It doesn't matter what type of water. Tap, boiled, bottled, spring, reverse osmosis filtered, cold, warm, room temp., etc. ALL water makes her nauseated. Normally I would think she might have some kind of mental aversion but it turns out her mother also has this same exact issue. 

If you have this issue please comment. I would like to know your blood type and rh factor (-/+). Just being curious. Thank you.

Hi, I think you might be right, maybe some kind of mental/psychological aversion. Water is one of our basic needs as a human. I think also this maybe a sensory defensive kind of aversion. I think they should seek professional help though.

I'm reading this anatomy book for artists, and there's a question that made me curious which probably a book for artists will not answer. I'm working on the skeleton now, and have just learned about the spine, and we're moving on to the upper limbs. Now, as I understand, the only bones connecting the arm bones (the humerus) to the rest of the skeleton, are the collar bones (clavicles), is that correct? I see there are the shoulder blades (scapulae) as well, but these do not seem to be connected to the rest of the skeleton, they are floating. Furthermore, the clavicles aren't really connected directly to the spine, but instead to the sternum, which is in turn connected to the spine via the ribs.

Now, if this was the only thing holding our arms connected to the rest of our body/skeleton, then it surely looks like a flimsy construction! Also, when looking at closeup drawings of it, it looks like the clavicles aren't even "trying" to keep the humerus from falling down. The clavicles just seem to sit on top of the scapulae and humerus without anything to hold them up. But a weight lifter can lift up to 260 kg, that's four times my own weight, maybe three times an average male's weight. So clearly the construction can withstand a lot of downwards force.

So, I haven't gotten to the muscles yet. Is it the muscles on top of our shoulders (I don't even know what they're called) that holds the whole thing up, even when we're not flexing them? How does this construction really work?

Heyyyy! Yes you are correct with the clavicle and the scapula. What holds our upper extremities together are muscles, tendons and ligaments. There are numerous ligaments and muscles that you will encounter when you proceed with your study. You will encounter Sternoclavicular Ligaments, Interclavicular ligaments, Acromioclavicular Ligaments and many many more!. Upper extremity is a fun topic to study, especially if you are into challenging memorization and analyzation. oh, you will encounter Kinesiologies as well so, keep it up! 

Well, there are certain parts of the brain that triggers emotions, not just positive ones. the Limbic System for example; which consists of 
Cingulate Gyrus, Parahypocampus, dentate nucleus, Hypocampus, the Amygdala, and the Hypothalamus. They are all linked to stimulate you emotional response. the positivity of emotions I believe links also to the hormonal changes of the body for example is Dopamine, or what we call the Happy hormones  I hope I explained it well.
