Answer:
Vertical allows people to nod, horizontal allows people to twirl
Explanation:
The vestibular system, which is key to our senses of balance, motion, and body position, is comprised of three semicircular canals connected to two membranous sacs called the saccule and utricle. The saccule and utricle are often referred to as the otolith organs. The otolith organs allow us to sense the direction and speed of linear acceleration and the position (tilt) of the head. The semicircular canals allow us to sense the direction and speed of angular acceleration. The semicircular canals are oriented along three planes of movement with each plane at right angles to the other two. Pilots and astronauts call these three planes of rotation pitch (<u>up and down; nod your head "yes")</u>, roll <u>(tumbling left or right; move your head from your left to your right shoulder or vice versa)</u>, and yaw (<u>lateral movement left and right; shake your head "no").</u>
<em>why does working out make us feel good?</em>
<em />
That "feel good" chemical is known as Endorphins. They are released during exercise because of the body goes through extended amounts of stress when exercising. Have you ever heard of the "Runners high"? It's actually a real sensation that you can thank Endorphins for.
Serotonin is also an important chemical that contributes to why exercise feels this way. Have you ever felt depressed after sitting around and doing nothing? Low serotonin is one of the biggest contributors to feeling depressed. Serotonin is in alot of anti-depressant medications. Serotonin is mainly released through exercise.
There could be a reason not relating to chemicals at all. Working out and seeing the results gives us a major confidence boost.
