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.
Generally, these muscles are attached to bones of the skeleton, thus called the skeletal muscles. Skeletal muscles are striated and are made up of multinucleate cells. Each cell is referred to as muscle fiber.The cell membrane of muscle fiber is known as sarcolemma, and the cytoplasm is called sarcoplasm. Unlike involuntary muscles, voluntary muscles are attached to bones. Involuntary muscles are visceral. â¢ Voluntary muscle tissue is made up of cylindrical fibres, while involuntary muscles (smooth muscles) are made up of spindle-shaped fibres.
