Myron- Hey Jacob, guess what awesome thing I learned today?

Jacob- What did you learn today Myron?

Myron- I learned about the kinesthetic sense. It provides information to the Parietal Cortex of the brain, letting it know the relative positions of your body parts.

Jacob-Woah! That's Fascinating! How does it do that?

Myron-Well, for example, every time you move your arm tiny sensory nerves send electrical pulses to the parietal lobe letting it know where your arm is relative to you body.

Jacob- Does that mean what I think it means?! That without the kinesthetic sense you wouldnt be able to move any of your body parts without directly looking at them?

Myron- Yea it does! Imagine not being able to walk down the stairs without staring at your feet the whole time!

Jacob- Do animals have this sense too?

Myron- Yes they do. In fact some birds and bees even have the ability to detect which direction they are facing based on the earth’s magnetic field.

Jacob- I wish I could do that... What else can you tell me about the kinesthetic sense?

Myron- Well there have actually been cases where a person who is blind from birth becomes an artist. They can draw portraits, landscapes, and even perspectives .They even dream in pictures even though their experiences consist from sound, textures, and temperatures. This is known as “kinesthetic awareness.”

Jacob- You know Myron, the kinestetic system is pretty interesting... But you know whats even cooler?

Myron- Nothing is cooler than the kinesthetic System!

Jacob- Then you haven't heard about the the vestibular system.

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Jacob- Well its similar to the kinesthetic system because it has to do with the movement and orientation of the body. It’s based in multiple parts of the body: such as the inner ear, the eyes, muscles and joints, fingertips, soles of the feet, and gravity receptors on skin. Its most active in the inner ear, the vestibular system has a very intricate and sensitive way of operating.

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Myron-Your right, that is pretty cool! But what makes it work?

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Jacob- The vestibular system is stimulated by the movement, rotation, and speed of the body.

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Myron- And how does it work?

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Jacob- Well, inside the ear is a series of three semi circular canals. Within them is a fluid, and when the body rotates or moves--even slightly--the fluid runs through the canal and stimulates small hair cells. Based on the hairs movement the brain determines the magnitude of the bodies movement or rotation.

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Jacob- Without the vestibular system, people wouldn't be able to walk without being overwhelmingly dizzy.

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Myron- Well Jacob, that is pretty scarry....awesome...What else can you tell me about this system?

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Jacob- Listen to this Fun Fact- in space travel--because it is based to work in a 1g environment--the vestibular system will often provide a person with incorrect information as to whether they are rotating or moving (this of course only happens if the subjects eyes are closed).

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Myron- Wow, I never knew how much went into determining our bodies movement!

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Jacob- I know right it is so fascinating, so next time you move around think about all of the steps the vestibular and kinesthetic systems take to keep you oriented and balanced.
