Brodmann Areas. Over a lifetime, the various parts of the brain that control the body's movements can suffer damage from various causes, such as head injuries, strokes, and degenerative brain diseases.One typical example is what happens when one side of the motor cortex is completely destroyed by a stroke.Because of crossed control, this centre normally controls the voluntary movements on the opposite side of the body.ne typical example is what happens when one side of the motor cortex is completely destroyed by a stroke.

Meckelâs diverticulum occurs in the small intestine. Small bowel obstruction can have many causes and depending on the level of obstruction, small bowel obstruction can present with abdominal pain, abdominal distension, vomiting, fecal vomiting, and constipation.
Although Meckel's diverticulum is the most prevalent congenital abnormality of the gastrointestinal tract, it is often difficult to diagnose. It may remain completely asymptomatic, or it may mimic such disorders as Crohn's disease, appendicitis and peptic ulcer disease. Ectopic tissue, found in approximately 50 percent of cases, consists of gastric tissue in 60 to 85 percent of cases and pancreatic tissue in 5 to 16 percent. The diagnosis of Meckel's diverticulum should be considered in patients with unexplained abdominal pain, nausea and vomiting, or intestinal bleeding.
