of the brain and spinal cord. Neurones are found throughout the body with the majority found in the central nervous system. Neurones are specialized to process information in the body. Neurones convey this information to one another through the stimulation of a detector neurone. This causing a brief change in the electrochemical gradient resulting in the neurone moving away from its resting potential. This is known as an action potential. Once initiated the action potential travels the length of

Nervous System: an extensive network of specialized cells that carries information to and from all parts of the body. Neuron: the basic cell that makes up the nervous system and that receives and sends messages within that system. Dendrites: branchlike structures that receive messages from other neurons. Soma: the cell body of the neuron responsible for maintaining the life of the cell. Axon: tubelike structure that carries the neural message. Glial cells grey fatty cells that provide support for

The nervous system is an important part of the human body. The system is made up of many different parts and each part is placed in either the central or peripheral nervous systems. These two parts work together and bring physical feelings and the proper reaction to them. The peripheral nervous system is the larger of the two systems. The peripheral nervous system consists of two more systems inside of it. The two other systems are the somatic and autonomic nervous systems. The somatic nervous system

Introduction Nervous systems are composed of circuits of neurons‚ highly specialized cells that communicate with each other and with other types of cells by electrical or chemical signals.—The central nervous system (CNS) is composed of brain and a nerve cord. The peripheral nervous system (PNS) consists of all neurons and their projections that are outside and connect with the CNS. The most basic circuits is a reflex arc‚ which occurs rapidly in response to inputs from the sensory neurons and

The autonomic nervous system (ANS) consists of three main anatomical divisions: sympathetic‚ parasympathetic and enteric nervous systems. The sympathetic (SNS) and parasympathetic (PNS) systems provide a link between the central nervous system and peripheral organs. The sympathetic nervous system originates in the spinal cord. Specifically‚ the cell bodies of the first neuron (the preganglionic neuron) are located in the thoracic and lumbar spinal cord. Axons from these neurons project to a
