From their common origin at a joint or tendon, ganglion cysts may form in a wide range of locations. Rarely, intraosseous ganglion cysts occur, sometimes in combination with a cyst in the overlying soft tissue. Very rare cases of intramuscular ganglion cysts in the gastrocnemius muscle of the calf have been reported.
What exactly is a âbomb cycloneâ? A bomb cyclone is a low-pressure system that intensifies very rapidlyâyou have to have a fall in pressure of at least 24 millibars in 24 hours to qualify as a âbomb cyclone,â or âbombogenesis,â event.
A large-scale system of winds that spiral in toward a region of low atmospheric pressure. A cyclone's rotational direction is opposite to that of an anticyclone. In the Northern hemisphere, a cyclone rotates counterclockwise; in the Southern hemisphere, clockwise. Because low-pressure systems generally produce clouds and precipitation, cyclones are often simply referred to as storms. An extratropical cyclone is one that forms outside the tropics at middle or high latitudes.
