 The body has this system called the nervous system, which includes the use of neurons, or nerve cells, these things talk to others with the use of chemical messenger. These chemical messengers are called neurotransmitters. When these things talk, they receive information from the world around them and the body’s tissues, they then decide, “ok what do we do now???” After this quick decision-making process, they then pass the information and orders back to the body’s tissue which tells them what to do. The big fat tofu like thing in your head and the thing that you always crack with a school seat (spine/back) are the things that make up your CNS or central nervous system, these are what the body uses to decide things. The peripheral nervous system (PNS) has the important job of taking all the information from the CNS and handing it out to other parts of the body. Like the Wi-Fi cables that give you all the information to the internet, the nerves connect the CNS with the body’s sensory receptors, muscles, and glands. Something that is absolutely bonkers is that the optic nerves are a single cable that contains a MILLION axons that take information from the eye to the brain. There are three main ways for information to travel through, there is the sensory neurons which is exactly what it sounds like, carries information from senses. The motor neurons which is also exactly like what it sounds like, information carried toward body’s muscles. Then there are the interneurons, which is IN between the sensory input and motor input, where the information is processed by them.
