The human body is an incredible system that is capable of working a multitude of diverse thought functions as well as muscle actions. Besides the bodies’ proficiency to move and reason, the human body also is comprised of the five senses that are involved in everyday life and even nightly life. The body’s ability to use the five senses, to preserve memories, and feel emotions are the outcome of the body’s basic elements of behavior. The body is employing these basic elements of behavior even gives the impressions that they are noticeable and simple. However, basic elements of behavior mixed and molded together with neurons, which has a remarkable diversity of responses unite to shape a unique and efficient system.- In the Feldman (2009) text, the book discusses of the framework of the body’s neural data system is neurons. “Neurons, or nerve cells, are the basic elements of the nervous system. Their quantity is staggering—perhaps as many as 1 trillion neurons throughout the body are involved in the control of behavior” (pg. 61) Each neuron is comprised of dendrites, a cell body, axon with myelin sheath, and vesicles with neurotransmitters. The neuron accepts data from sense receptors or from chemical correspondences from neighboring neurons via its dendrites, which move the data to the cell body. The correspondences that journey through a neuron are electrical in nature.- In addition, the text gives examples of how the cell body fires an impulse, called the action potential, down the axon. The impulse is projected and rushed along its way by the myelin sheath, which is a layer of fatty tissue that encases the axon. All neurons recognize signals from numerous other neurons. There are two kinds of signals, one is excitatory, becaus... ... middle of paper ... ...ipheral nervous system or PNS is one of the two core portions of the body’s nervous system. “The peripheral nervous system branches out from the spinal cord and brain and reaches the extremities of the body. Made up of neurons with long axons and dendrites, the peripheral nervous system encompasses all the parts of the nervous system other than the brain and spinal cord.” The peripheral nervous system is divided into dual parts called the somatic nervous system and the autonomic nervous system. The peripheral nervous system behaves as a joiner to the central nervous system. The part of the peripheral nervous system known as the somatic nervous system is made of cranial nerves and spinal nerves. The nerves of the somatic nervous system supply the muscular system and external receptors; this is part of the body control and enables movement (Feldman, 2009 pg 69-70).-
