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.
1.Skeletal muscles are attached to the bones. Smooth muscles line up the visceral organs viz. Intestines,blood vessels,pupils etc (therefore also known as visceral muscles.) 2.Skeletal muscles perform voluntary actions. Smooth muscles are responsible for involuntary reflexes and actions.
While most of the processes are similar, there are some notable differences between the actions of skeletal, cardiac and smooth muscle. Cardiac-muscle cells are striated, and are a lot like skeletal-muscle cells except that in cardiac muscle, the fibers are interconnected.
