The human body is regulated by the nervous system and its functions. Under normal circumstances everything runs smoothly with no issues; however, fear can have an impact on how the nervous system works. One aspect that can be examined in relation to the nervous system and the ways that fear affects it is through body temperature regulation. When fear is present it bring on the production of specific hormones that cause certain responses within the body leading to the flight or fight situation. As with any function of the body there are impairment that are always possible as well. Knowing in advance what types of things can impair one's thermoregulation process gives people a step up against having issues later in life.
The nervous system consists of two parts, the central nervous system (CNS) and the peripheral nervous system (PNS) (National Institute of Health [NIH], 2013). Each part plays a role in our bodily functions. The CNS is made up of the brain and the spinal cord, the PNS is made up of the all the branch-like fibers that come off the spinal cord and reach all over the body- arms, legs, face, neck, etc. Without the nervous system there would be no way to get information from the brain to the rest of the body; all the messages that our brain sends out must be sent though the nervous system through neuron communication. "Neurons communicate with each other using axons and dendrites. When a neuron receives a message from another neuron, it sends an electrical signal down the length of its axon. At the end of the axon, the electrical signal is converted into a chemical signal, and the axon releases chemical messages called neurotransmitters" (NIH, ¶ 3). This process is how the brain tells...
