Problem: The nervous system plays an important role in wellness because it is how the body communicates. It contains billions of neurons that send and receive signals across synapses using neurotransmitters (Straub, 2023). It is divided into the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which includes the nerves throughout the body. The peripheral nervous system itself is divided into two subdivisions: the somatic nervous system, which manages voluntary movement, and the autonomic nervous system, which manages involuntary functions such as heart rate, digestion, and breathing (Straub, 2023).
