The skeletal system of the body is composed of bones which help in the normal posture in a human being. This skeletal system helps in different types of movement with the help of the muscular system. It is composed of bones to which are attached muscles, tendons and ligaments. The primary function of skeletal system is in the movement of different body parts and also in protection of the viscera of the body (Hall & Guyton 2006).
Muscular system is the system which helps the bones to move in accordance to their contraction and relaxation. They also help in involuntary movements taking place inside the body. Muscular system is made up of muscles tendons and ligaments. Muscles are of three types respectively known as cardiac, skeletal and smooth muscle. These three types of muscles serve different functions in the body. Skeletal muscle are voluntary muscles which are under the control of the human beings whereas smooth muscles are not. Cardiac muscle are located in the heart which help in the contraction and relaxation of heart (Hall & Guyton 2006).
Nervous system is a system which contains specialized cells located all over the body which help in all the bodily functions. The components of nervous system include the central nervous system and the peripheral nervous system. The central nervous system contains of the brain and spinal cord whereas the peripheral nervous system contains the neurons which help in connecting the body parts to the central nervous system. Both of these systems coordinate their activities together in order to produce the desired effect by the body (Snell 2004).
