Pain diarrhea: Ileitis is inflammation of the ileum (part of the small intestine). It can cause abdominal pain, fever and diarrhea.
The primary motor cortex (Brodmann area 4) is a brain region that in humans is located in the dorsal portion of the frontal lobe.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.
Like all parts of the neocortex, the primary motor cortex is made of six layers (Figure 3.6). Unlike primary sensory areas, primary motor cortex is agranular cortex; that is, it does not have a cell-packed granular layer (layer 4). Instead, the most distinctive layer of primary motor cortex is its descending output layer (Layer 5), which contains the giant Betz cells. These pyramidal cells and other projection neurons of the primary motor cortex make up ~30% of the fibers in the corticospinal tract. The rest of the fibers come from the premotor cortex and the supplementary motor area (~30%), the somatosensory cortex (~30%), and the posterior parietal cortex (~10%).
