If a gallstone obstructs the common bile duct just after the pancreatic duct joins it, flow of pancreatic juice from the pancreas is blocked. This results in inflammation within the pancreas. Pancreatitis due to gallstones usually is mild, but it may cause serious illness and even death.
Classically the motor cortex is an area of the frontal lobe located in the dorsal precentral gyrus immediately anterior to the central sulcus.ocated on the midline surface of the hemisphere anterior to the primary motor cortex. 1  The posterior parietal cortex is sometimes also considered to be part of the group of motor cortical areas; however it is best to regard it as an association cortex rather than motor.
At the primary motor cortex, motor representation is orderly arranged (in an inverted fashion) from the toe (at the top of the cerebral hemisphere) to mouth (at the bottom) along a fold in the cortex called the central sulcus.However, some body parts may be controlled by partially overlapping regions of cortex.ne of the most common misconceptions about the primary motor cortex is that the map of the body is cleanly segregated. Yet it is not a map of individuated muscles or even individuated body parts. The map contains considerable overlap. This overlap increases in more anterior regions of the primary motor cortex.
