		The somatic nervous system is the voluntary part of the nervous system that coordinates a body's movements, such as maintaining a particular posture and walking.
		The sympathetic nervous system responds to impending danger or stress, and is responsible for the increase of one's heartbeat and blood pressure, among other physiological changes, along with the sense of excitement he feels.
		The parasympathetic nervous system, on the other hand, is evident when a person is resting and feels relaxed, and is responsible for such things as the constriction of the pupil, the slowing of the heart, the dilation of the blood vessels, and the stimulation of the digestive and geniturinary systems.

	Autonomic nervous system Summary
		The autonomic nervous system (ANS) is the part of the nervous system of the higher life forms that is not consciously controlled.
		A third and less commonly considered part of the autonomic nervous system is the enteric nervous system, which controls the digestive organs, and is, for the most part, independent of central nervous system (CNS) input.
		In general, the parasympathetic nervous system is involved with digestion and energy conservation, while the sympathetic nervous system is involved with energy expenditure and the 'fight or flight' response.

	The Autonomic Nervous System
		The autonomic system is usually defined as a motor system that innervates three major types of tissue: cardiac muscle, smooth muscle, and glands.
		A third division of the autonomic system, termed the enteric nervous system, consists of a collection of neurons embedded within the wall of the entire gastrointestinal tract and its derivatives.
		This is characterized by the release of large quantities of epinephrine from the adrenal gland, an increase in heart rate, an increase in cardiac output, skeletal muscle vasodilation, cutaneous and gastrointestinal vasoconstriction, pupillary dilation, bronchial dilation, and piloerection.

		The somatic nervous system is that part of the peripheral nervous system associated with the voluntary control of body movements through the action of skeletal muscles, and with reception of external stimuli, which helps keep the body in touch with its surroundings (e.g., touch, hearing, and sight).
		The somatic nervous system processes sensory information and controls all voluntary muscular systems within the body, with the exception of reflex arcs.
		The basic route of nerve signals within the efferent somatic nervous system involves a sequence that begins in the upper cell bodies of motor neurons (upper motor neurons) within the precentral gyrus (which approximates the primary motor cortex).

		This system is in charge of gathering and transmitting the information detected by the senses, and also of sending instructions that allow the voluntary movement of the muscles.
		The somatic nervous system (SNS) is made up of sensory neurons that carry information (for instance, pain) from the sensory receptors (of the senses: skin, eyes, etc.) -mainly located in the head, body surface and limbs- to the central nervous system (CNS).
		Thus, the somatic nervous system has two canals: one as an entry, where the information is received (through somatic sensory or somatic afferent canals), which is related with temperature, pain, touch, pressure and space senses (sight, hearing, taste and smell) and also, the proprioception, which corresponds to the information gathered at the muscles and tendons.

	What is the Peripheral Nervous System?
		The peripheral nervous system (PNS) is one of the two main parts of the body’s nervous system.

		It is also the part of the nervous system that regulates internal processes such as increased and decreased heart rates as a response to stimuli, secretion of digestive fluids, and the body’s reaction to stress.
