The Musvous System: Roles And Functions Of The Body

The body is made up of many systems working together as a whole and the most significant one is the nervous system. The nervous system is responsible for making sure the rest of the body does what it needs and without this elaborate electrical system the body would have no meaning. There are many components to this beautiful labyrinth of nerves that allows us to be the marvelous humans we are. This system is complicated in itself but broken down into its peripheral, somatic, autonomic, and central functions it becomes much simpler. One integral part of the nervous system is the peripheral nervous system. This structure is full of microscopic craniospinal nerves. These specific nerves are little tree like branches connected to and from the brain and spinal …show more content…
The somatic nervous system controls the skeletal muscles and external organs of the body. Examples of these organs would include: the skin, nails, and the protective covering of everything on the body. The controls included under somatic that control the skeletal muscles would be voluntary or anything you can control consciously except for reflex reactions. The body needs this influential system to manage any movement of the body that we can physically control. Autonomic functions is the kin of the somatic which controls any involuntary actions of the body. Muscles that are under the force of the autonomic include: the smooth and cardiac muscles. This system has split divisions that help control the body. A parasympathetic division is used to control functions like slowing the heart rate down and contracting the bladder. The sympathetic division is used to then speed up the heart rate and relax the bladder. These two divisions work together to complete the functions of the autonomic system. Working together the somatic and autonomic systems make up the body’s ability to move throughout the day even without us knowing anything about
