Mechanoreceptors+project+CH

=__Mechanoreceptors__=
 * Mechanoreceptors are sensory receptors that respond to mechanical stimuli such as tensions or pressure.
 * There are three main types


 * 1) Hearing
 * 2) Touching
 * 3) And the Equilibrium

=__My Focus: Equilibrium__=
 * **"Equilibrium** is the condition of a system in which competing influences are balanced"
 * In basic terms equilibrium is the sense of balance

How Equilibrium Works:

 * The vestibular nerve (located in the semicircular canals, saccule, and utricle) move impulses of the nerves to the brain stem and cerebellum
 * This communication alows the body to reach equilibrium (with the help of other body parts)
 * Those other body parts include proprioceptors, which are necessary for balance
 * The semicircular canals are related to the rotational movement of the heard
 * The utricle and saccule are related to the gravitational pathway (gravity obviously has an affect on equilibrium)
 * Equilibrium Prevents Dizziness**
 * Since equilibrium is providing balance, it is a prevention of dizziness
 * Dizziness is a "physical unsteadiness, imbalance, and lightheadedness associated with balance and other disorders."
 * So, if your body has equilibrium, you will not be dizzy
 * When your equilibrium is out of wack, you will then become dizzy



**Nerves Involved:**

 * Hair cell nerves on the neck
 * Nerves down the spinal cord
 * The nerves relay the message to the brain

What Causes Dizziness?

 * When we spin around, the cupula moves in the same direction we spin


 * This bends the stereocilia which sends the message to the brain that the body is spinning too fast for all the parts to work together to achieve equilibrium
