Neural Structure And Function Meaning What is a neuron Neurons are the structural and functional unit of the nervous system All neurons have three different parts dendrites cell body and axon The neuron structure is specially adapted to carry messages over large distances in the body quickly in the form of electrical signals Q2
Neurons are the basic units of the nervous system that transmit electrical and chemical signals throughout the body In this article you will learn about the structure and function of different types of neurons as well as how they communicate with each other Khan Academy is a free online platform that offers courses in various subjects including biology There are three main categories of neurons motor neurons sensory neurons and interneurons Each is responsible for a different aspect of perception and movement as well as essential brain functions like learning and decision making This article provides an overview of neurons the types of neurons their structure and how they work

Neurons vary in size shape and structure depending on their role and location However nearly all neurons have three essential parts a cell body an axon and dendrites The nervous system consists of two main cell types neurons and supporting glial cells The neuron or nerve cell is the functional unit of both the central nervous system CNS and the peripheral nervous system PNS The basic functions of neurons can be summarized into four main tasks receiving signals integrating these signals generating signals and transmitting the signals to target
Neuron parts have specific functions as discussed under the preceding heading Neurons are the electrical cables of the body Think of the dendrites as the pins that enter a wall socket the soma as the fused plug the cable as the axon and where the cable attaches to a device is the terminal Not so different from a neural network Nervous tissue present in both the CNS and PNS contains two basic types of cells neurons and glial cells A glial cell is one of a variety of cells that provide a framework of tissue that supports the neurons and their activities The neuron is the more functionally important of the two in terms of the communicative function of the nervous system

Neurons or nerve cell are the main structural and functional units of the nervous system Every neuron consists of a body soma and a number of processes neurites The nerve cell body contains the cellular organelles and is where neural impulses action potentials are generated The processes stem from the body they connect neurons with Different types of neurons include sensory motor and interneurons as well as structurally based neurons which include unipolar multipolar bipolar and pseudo unipolar neurons These cells coordinate bodily functions and movement so quickly we don t even notice it happening 9 Sources By Kevin James Cyr
Definition Neuron a late nineteenth century Greek term refers to highly specialized nerve cells that conduct electrical impulses Action potential This innate propensity to generate and conduct electrical potentials is a unique hallmark of all excitable cells of which the neurons are the most specialized Structure and Function However neural progenitors that are capable of participation in neurogenesis are present in certain regions such as the dentate gyrus of the rat and in the subependymal of rodents There is a continuing interest in potential therapeutic uses for neural progenitor cells following injury Nerves In the periphery
