Cutaneousinnervation refers to the area of the skin which is supplied by a specific nerve , that is, by a cutaneous nerve . Dermatome Anatomy Dermatome s are similar however, a dermatome only specifies the area served by a spinal nerve . In some cases, the dermatome is less specific when a spinal nerve is the source for more than one cutaneous nerve , and in other cases it is more specific when a cutaneous nerve is derived from multiple spinal nerves. Modern texts are in agreement about which areas of the skin are served by which nerves, but there are minor variations in some of the details. The borders designated by the diagrams in the 1918 edition of Gray s Anatomy , provided below, are similar but not identical to those generally accepted today. Importance of the peripheral nervous system The peripheral nervous system PNS is divided into the somatic nervous system , the autonomic nervous system , and the enteric nervous system . However, it is the somatic nervous system, responsible for body movement and the reception of external stimuli, which allows to understand how cutaneousinnervation is made possible by the action of specific sensory fibers located on the skin , as well as the distinct pathways they take to the central nervous system. The skin, which is part of the integumentary system , it plays an important role in the somatic nervous system because it contains a range ... system in cutaneousinnervation.

Unreferenced auto yes date December 2009 Ren Descartes 1596 1650 was one of the first to conceive a model of reciprocal innervation in 1626 as the principle that provides for the control of Agonist muscle agonist and Antagonist muscle antagonist muscle s. Reciprocal innervation describes skeletal muscles as existing in antagonistic pairs, with contraction of one muscle producing forces opposite to those generated by contraction of the other. For example, in the human arm , the triceps brachii muscle triceps acts to Extension kinesiology extend the lower arm outward while the biceps brachii muscle biceps acts to Flexion flex the lower arm inward. In order to reach optimum efficiency, contraction of opposing muscles must be inhibited while muscles with the desired action are excited. This reciprocal innervation occurs so that the contraction of a muscle results in the simultaneous relaxation of its corresponding antagonist. A common example of reciprocal innervation, is the effect of the nocifensive reflex, otherwise commonly known as the withdrawal reflex a type of involuntary action of the body to remove the body part from the vicinity of an offending object by contracting the appropriate muscles usually flexor muscles , while relaxing the extensor muscles. The significance of Descartes Law of Reciprocal Innervation has been additionally highlighted by recent research and applications of bioengineering concepts, such as optimal control and quantitative models of the motor impulses sent by the brain to control eye motion.

Hering s law of equal innervation is used to explain the conjugacy of saccade saccadic Eye movement sensory eye movement in stereoptic animals. The law proposes that conjugacy of saccades is due to innate connections in which the eye muscles responsible for each eye s movements are innervated equally. The law also states that apparent monocular eye movements are actually the mathematical summation of conjugate version eye version and vergence eye movements. The law was put forward by Ewald Hering in the 19th century, though the underlying principles of the law date back considerably. Aristotle had commented upon this phenomenon and Ptolemy put forward a theory of why such a physiological law might be useful. ref name Wade1998 cite book author Wade, N.
