 | | The central nervous system consists of the brain and spinal cord. | | | All of the fibers of the autonomic nervous system are motor channels, and their impulses arise from the nerve tissue itself, so that the organs they innervate perform more or less involuntarily and do not require stimulation to function. | | | The spinal nerves arise in the spinal cord, 31 pairs radiating to either side of the body: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. |

| | The nervous system consists of the brain, the spinal cord, and the network of nerves throughout the rest of the body. | | | The nervous system provides a rapid means for the various parts of the body to communicate with each other. | | | The central system is the brain and spinal cord, and is where most information is processed. |

| | Receptors are parts of the nervous system that sense changes in the internal or external environments. | | | The autonomic system controls muscles in the heart, the smooth muscle in internal organs such as the intestine, bladder, and uterus. | | | Input to the nervous system is in the form of our five senses: pain, vision, taste, smell, and hearing. |

| | Nervous System |
| | The somatic nervous system is responsible for the voluntary control of skeletal muscle and for the collection of sensory information from the body. | | | Motor fibres from the sympathetic and parasympathetic divisions of this system control involuntary striated muscle such as that in the heart, and involuntary smooth muscle such as that in the respiratory, digestive, cardiovascular, renal and reproductive systems. | | | The fibres of the parasympathetic system are found in some cranial nerves and in the sacral 2,3,4 spinal nerves. |

| | 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 genitourinary systems. | | | The somatic nervous system is responsible for coordinating the body's movements, and also for receiving external stimuli. | | | For example, the human brain is part of the nervous system. |

| | The ANS |
| | Through these nervous pathways, the autonomic nerves convey stimuli resulting in largely unconscious, reflex, bodily adjustments such as in the size of the pupil, the digestive functions of the stomach and intestines, the rate and depth of respiration and dilatation or constriction of the blood vessels. | | | The autonomic nervous system conveys sensory impulses from the blood vessels, the heart and all of the organs in the chest, abdomen and pelvis through nerves to other parts of the brain (mainly the medulla, pons and hypothalamus). | | | The afferent nerves subserving both systems convey impulses from sensory organs, muscles, the circulatory system and all the organs of the body to the controlling centers in the medulla, pons and hypothalamus. |

| | Herbs and the Nervous System |
| | Recent experiments at the University of Heidelberg have confirmed that the action of the volatile oil begins within the limbic system of the brain and subsequently operates directly upon the vagus nerve and all of the organs that are innervated by it. | | | Because herbal medicine is holistic medicine, it is, in fact, able to look beyond the symptoms to the underlying systemic imbalance; when skillfully applied by the trained practitioner, herbal medicine offers very real and permanent solutions to very real problems, many of them seemingly intractable to pharmaceutical intervention. | | | Melissa officinalis (Lemon Balm) being both carminative and antispasmodic, is active specifically on that part of the vagus nerve which may interfere with the harmonious functioning of the heart and the stomach. |

| | The Limbic System |
| | It also regulates the functioning of the parasympathetic and sympathetic nervous systems, which in turn means it regulates things like pulse, blood pressure, breathing, and arousal in response to emotional circumstances. | | | The first is the sympathetic nervous system, which starts in the spinal cord and travels to a variety of areas of the body. | | | It provides a pathway from the thalamus to the hippocampus, seems to be responsible for focusing attention on emotionally significant events, and for associating memories to smells and to pain. |

| | Always remember that visceral sensation is independent of the autonomic system, but the afferent axons follow through the same nerves as the efferents--both of the sympathetic and parasympathetic. | | | This ganglion also receives the preganglion Edinger-Westphal axons, and the postsynaptic fibers of this pathway are referred on to their innervation of smooth intrisic muscles of the eye. | | | The general opinion is that there are no specialized sensory receptors in the genital organs involved with sexual excitation and gratification, but the unique sensory response leaves this question open. |
