Example Answer:
We know that all humans have five senses these are sight, taste, smell, hearing and touch. But actually, there is a “sixth sense” which is known as vestibular system.
Vestibular system helps us to sense our body movement combined with our ability to maintain body balance. A body has ability to sense and determine in which direction and with which speed the body is moving and with the help of this information body can maintain its balance. A blind man rely on his vestibular sense for this information. Body vestibular system is designed to work on the ground. So in space it can provide erroneous or disorienting information. Astronouts are trained for adaptation strategies to enter in a microgravity environment. When astronouts return back to earth in normal environment they feel dizziness and disorientation.
Hope this helps!
As humans, we basically have 5 senses which are the hearing, touch, sight, taste and smell.
It is learned that there is a sixth sense in human called the Proprioception. This sense has the ability to sense the orientation of our body in any environment. This sense helps the body sense movement and body balance.
What is the Vestibular system?
It is the sensory inner ear which helps the body to maintain posture. It coordinates the position of the head and movement of the eye.
This sense called vestibular system is designed to work on the ground. It allows one to keep track of the body even in space.
Due to this sixth sense, Astronauts are trained for adaptation strategies to get into the micro-gravity world and survive there.
This causes them (astronauts) to feel dizzy and disoriented when they return to earth.
