I don't mean to be blunt or dismissive, but the pressure in the veins/arteries has nothing to do with (a) the thickness/elasticity of the wall tissue, (b) the diameter of the arteries/veins, or (c) the number of (branches of) arteries/veins.
This can either be caused by a more prominent maxilla (upper jaw) or a retruded mandible (lower jaw further back than it should be). This causes a discrepancy in how all teeth contact, and can manifest as an increased overjet. An increased overjet can also be caused by a discrepancy in the number of teeth, or the length of the arch.
For anyone who doesn't understand what's going on, turbulence can prompt fears that the airplane will go out of control or be damaged. As with most fears, knowledge is the antidote. Turbulence isn't going to bring down your plane. Only extreme turbulence is likely to damage an aircraft.Fortunately, extreme turbulence is rare and pilots with a basic knowledge of what causes turbulence can avoid it.y Jack Williams, USATODAY.com. Anyone who's made more than a few flights has almost surely had at least one b umpy ride when the airplane felt like a car on a rough road, except that the airplane might have rolled from side to side as well as bouncing up and down.
