Parts of Nervous System. Nervous System: Nervous system is the chief controlling and coordinating system of the body. It controls and regulates all activities of the body, whether voluntary or involuntary, and adjusts the individual (organism) to the given surroundings.
Compared to skeletal muscle, smooth-muscle cells are small. They are spindle-shaped, about 50 to 200 microns long and only 2 to 10 microns in diameter. They have no striations or sarcomeres. Instead, they have bundles of thin and thick filaments (as opposed to well-developed bands) that correspond to myofibrils.
Best Answer: Skeletal muscles are striated-they look striped in the direction their fibres grow. Smooth muscles are, well, smooth. Look closely at a picture of a competitive bodybuilder striking a pose-you'll notice that his muscles look stripy. They are more obvious they bigger the muscles are and the less fat there is under the skin to obscure them. Source(s):
