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.
Constipation may cause faeces to pack the intestine and rectum so tightly that the normal pushing action fails and the colon is not strong enough to expel the stool. This is called faecal impaction. Accidental loss of faeces, i.e. faecal incontinence can occur in those with constipation when the bowel becomes too full. Haemorrhoids can be caused by straining to have a bowel movement. Anal fissures (tears in skin around anus) are caused when a hard stool stretches the sphincter muscle. In extreme cases straining can cause a small amount of intestinal lining to push out from the anal opening causing a rectal prolapse.
