if they do not enter into our daily lives?

Rolling down a hill or spinning around in endless circles causes dizziness or vertigo because hair-like sensory nerve cells in our ears send wrong messages to our brain. canada viagra generic The motions of our bodies are detected by the vestibular system found in the upper part of our inner ear. The vestibular system senses whether we are standing up or lying down. When we spin in circles or get up too fast from the couch, we feel dizzy and lightheaded due to the vestibular system's nerve reactions to these unusual motions. Here's how our vestibular system reacts to a slight change in direction when we bend our heads:   the vestibular system senses motion through three semicircular canals that are at right angles to one another. http://medicaresupplementspecialists.com/pfz-buy-online-viagra-pa/ Not only do these canals have hair-like sensory nerve cells, but they also contain a fluid called endolymph. viagra vardenafil 100 mg bayer 30 tablet Following the principle of inertia, endolymph resists changes in motion. buy viagra online from canada drugs As a result of this resistance, the endolymph lags behind and stimulates hair cells to send nerve signals to the brain. Our brain interprets the nerve messages and knows which direction the head moved. viagra online However, when we spin, our brain receives mixed messages. The endolymph slowly begins to move in the same direction we are spinning. viagra for sale As time goes by, the endolymph catches up to the rate of speed we are spinning and no longer stimulates the hair-like nerve cells. This causes our brain to quickly adapt to the nerve signals. viagra without a doctors prescription However, when we stop spinning, the endolymph continues to move and stimulates hair cells in the opposite direction. These hair cells send wrong messages to the brain making it think that the head is still spinning although it actually has stopped. As a result of this inaccurate signal, we experience dizziness. http://nationalityinworldhistory.net/bsh-viagra-non-prescription-alternative-uc/ Eventually, the endolymph stops moving and no more signals are sent to the brain. viagra vardenafil 100 mg bayer 30 tablet The brain interprets that the spinning motion has ceased and the dizziness disappears.
