![]() ![]() The somatic nervous system works in two main ways - to control voluntary movement and to process sensory input. For example, when you urinate, the autonomic nervous system causes smooth muscle contraction to enable urine to leave the bladder, but some somatic (voluntary) movement is needed to urinate. The somatic nervous system and autonomic nervous system work in tandem. This part of the neural pathway controls mainly voluntary muscle movements (skeletal muscles) but also some involuntary muscle responses (reflexes). Meaning you choose when to activate electrical impulses in this part of the nervous system. The somatic nervous system is the voluntary nervous system. Electrical signals in the autonomic nervous systems (sympathetic and parasympathetic) control involuntary body processes, such as breathing, heart rate, blood pressure, digestion, sexual arousal, and the fight or flight response. The peripheral nervous system is further divided into the somatic nervous system and the autonomic nervous system. The peripheral nervous system consists of all the nerves that connect the central nervous system and various parts of the body, such as the organs, glands, and muscles. The central nervous system is made up of the brain and spinal cord. The human nervous system consists of two main parts. What is the somatic and autonomic nervous system? Please continue reading to learn more about this vital part of the human body. Guess what? In both instances, you’ve used your somatic nervous system. Or, you touch a hot pan and immediately withdraw your hand with a skeletal muscle movement that is an involuntary reflex. In response to this thought, your brain sends a signal to your arm and causes skeletal muscle contraction, which enables you to pick up the book. You settle down on your couch and decide to read a book lying on your coffee table. ![]()
