The Nervous System
What is the Nervous System and how does it work? The Nervous system is a complex System made up of many smaller complex system. The Nervous system is the system of your body that controls all of your nerves the nerves that connect to your senses, brain, spinal cord, and many other things.
The Nervous system is one big system that is made up of many systems the control all the nerves in your body. The nervous system has two main parts the Peripheral nervous system and the central nervous system. The Central nervous system is made up of the brain and the spinal cord. The brain and the spinal cord are made up of the Forebrain, Midbrain, and Hindbrain. The Peripheral Nervous System is made up of the Autonomic Nervous System

The Autonomic NS regulates the process of breathing and digestion. The Autonomic System is made up of the Sympathetic system an and the parasympathetic system. The actions of the Sympathetic system is to speed up the heartbeat, sending blood to the muscles and helping eyes to use light. The parasympathetic system is to slow down the heartbeat and not sending blood to the muscles and the stomach and other internal organs. “Nervous System” The Autonomic system is made up of two systems that have the opposite effect but on the same set of organs. The Sympathetic nervous system is used during emergency also know as the flight or fight response. The Sympathetic nervous system is suppose to dilate the pupils, make your heartbeat faster, make you breathe faster, etc. The Parasympathetic system is also known as the relaxed state. Which does the exact opposite of the Sympathetic nervous system which means it slows your heartbeat regulates your breathing etc.(Life …show more content…
They are the sensory neurons they transmit and carry messages to the central nervous system. The motor neurons which relay information from the nervous system to other parts of the body. "Somatic Nervous System Definition, Function, and Example” The main role of your Somatic Nervous System is to connect the central nervous system to the organs, muscles, and skin. This is so that you can make complex movements. The somatic system also sends messages to the nerves that have to do with your senses. Sensory/afferent neurons carry impulses to the central nervous system and the brain. After being processed the somatic system takes the message back to the muscles and sensory organs. There are 12 pairs of cranial nerves and 31 pairs of spinal nerves which are made up of sensory cells and motor cells while others have both. Smelling and seeing only have sensory cells. Eyeball movement (not vision) and hearing only have motor cells. While others like taste and swallowing have both. ("Somatic Nervous System Definition, Function, and Example) The somatic nervous system also have nerve fibers that pick up sensory. For example if you touch something hot the motor nerve fibers carry information to the brain telling it there is something hot so the nerve tells your hand to withdraw from the hot object. “Function of the Nervous
