Video: Sympathetic Nervous System: Definition, Function & Effects. The autonomic nervous system is the portion that controls all of the involuntary functions of the body. This includes the body's response to emergency situations. In this article, we discuss the sympathetic nervous system and its responses under these circumstances.
The neurons system is divided into the central nervous system (CNS- the brain and spinal cord) and the peripheral nervous system (PNS), which connects to CNS to the rest of the body by means of nerves. The PNS has two main divisions. The somatic nervous system enables voluntary control of the skeletal muscles. The autonomic nervous system, through its sympathetic and parasympathetic divisions, controls involuntary muscles and glands. Neurons are the basic building blocks of the nervous system. Sensory neurons carry incoming information from sense receptors to the brain and spinal cord, and motor neurons carry information from the brain and spinal cord out to the muscles and glands. Interneurons communicate within the brain and spinal cord and between sensory and motor neurons.
