How the human body adapts to tremendous G force during acceleration and the effects it has on the human body both physically and mentally. Every moment, sense birth we have been battling the forces of gravity (1 G); we experience new concepts, like falling. How do we fall? What makes us keep from floating in the air? What allows us to fly? How can we sustain acceleration while flying? From childhood to adulthood we constantly discover new things. As individuals and as mankind, we sent a man to the moon. The Wright brothers created the first flyable plane. Yet even before all of this, flying history dates back to 400 BC in China. The Chinese would make kites for fun, here they discovered the concept of flying, sense then there have been many …show more content…
If the pilot is successful with the dive +G^x will cause the heart and CVS to beat incredibly faster in order to keep the blood flowing toward the brain. Without sudden response, the pilot may often find themselves in a very dangerous position. This is called GLOC. GLOC stands for G-induced loss of conscious. The first realization of GLOC will be a gradual loss of vision. Because eyes are sensitive to low blood flow, the vascular system cannot keep up with onset of the Gs and the retina will not be supplied with adequate blood flow. As the arterial pressure in the eye falls below the needed amount for the retina, the pilot may loss his peripheral vision, AKA, tunnel vision. Soon after this is progressive degradation to the smaller visual field (gun barrel vision) and then very quickly followed by grey out, and or blackout. If the maneuver is gradual there will be preceding warnings telling you to back down, on the other hand, if the onset is rapid GLOC will occur without visual warnings and make these steps fatal. GLOC is the greatest cause of military and civilian …show more content…
The outer section of the ear to the tympanic membrane (ear drum), the middle ear (an air filled cavity containing three small bones called ossicles) these transmit and amplify sound between the ear drum and the cochlea, and the inner ear which contains the cochlea and the vestibular system. These are the main parts of the ear. The vestibular system contained in the inner ear is composed of three semicircular canals these are connected to two membranous called the saccule and the utricle. These otolith organs allow us to sense the direction and speed in linear acceleration and the position of the head. These are oriented along three paths of motion, roll, pitch, and yaw. (Rolling, up and down, and side to side.) These canals allow people to sense angular acceleration. The vestibular system also allows the eyes to stay fixed on a specific object, which can be very important for flying. With this enabled you can move your head any which way while still concentrating on the object. These semicircular canals are a set of three membranous tubes that are imbedded within a look-alike bony structure. Each of the center cavities is filled with a fluid called endolymph. Near this area is an open space called an ampula. Bits of the v. nerve enter the base of the ampula and become what is generally known as hair. These hair cells are contained in a mound like structure called the ampullary
