Nerves that exit from the cranium are called cranial nerves while those exiting from the spinal cord are called spinal nerves. Both autonomic and enteric nervous systems function involuntarily. The enteric nervous system functions to control the gastrointestinal system. The sympathetic nervous system is activated in cases of emergencies to mobilize energy, while the parasympathetic nervous system is activated when organisms are in a relaxed state. The autonomic nervous system is further subdivided into the sympathetic and the parasympathetic nervous systems. Somatic nerves mediate voluntary movement. The PNS is divided into a) somatic and b) autonomic nervous system, and c) the enteric nervous system. Most nerves serve both functions and are called mixed nerves. Nerves that transmit signals from the brain are called motor or efferent nerves, while those nerves that transmit information from the body to the CNS are called sensory or afferent. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers or axons, that connect the CNS to every other part of the body. The CNS contains the brain and spinal cord. In vertebrate species it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). Nervous tissue first arose in wormlike organisms about 550 to 600 million years ago. Nervous system The nervous system is the part of an animal's body that coordinates its actions and transmits signals to and from different parts of its body.
