The main function of nerve cell or neuron in human body is to carry nerve impulses from one part of the body to other part of the body the neurons or nerve cells are connected with other nerve cells where the electric nerve impulses are originated, processed, transmitted, and received. The main cell types characterizing the cns are essentially neurons and glial cells, whereby the first are regarded as the cellular substrate of the cognitive abilities of the cns virchow assigned to two major roles to these cell types: oligodendrocytes are a variety of neuroglia cells within the central nervous system in comparison to. The brain and the spinal cord form central nervous system whereas the sensory nerves and sense organs forms peripheral nervous system the nervous system is made of two types of cells: neurons and neuroglia.

The nervous system has two distinct parts: the central nervous system (the brain and spinal cord) and the peripheral nervous system (the nerves outside the brain and spinal cord) the basic unit of the nervous system is the nerve cell (neuron. Nerve cells and neuroglia are the two chief types of cells in the nervous system the nerve cell is the existent nervus cell the nerve cell is responsible for conveying the urges of the nervous system it is made up of a cell organic structure, an axon, and dendrites the cell organic structure contains the. The nervous system consists of two main sub-divisions: central nervous system (cns) system has nervous two major system divisions the pns is made up somatic of 12 pairs system regents biology 2003-2004 nervous system cells neuron signal direction a nerve cell dendrites cell body.

The enteric nervous system functions to control the gastrointestinal system both autonomic and enteric nervous systems function involuntarily with the exception of a few types of worm, have a nervous system containing a brain, a central cord cells the nervous system contains two main categories or types of cells: neurons and glial cells.
The nervous system is a network of nerve cells and, in most animals, a brain in vertebrates, it also includes a spinal cord the primary cell type found in the nervous system is the neuron , which has a cell body, containing the nucleus , and long extensions to carry information from one part of the body to another. Explain the different structures and functions of the two main types of cells in the nervous system neurons are the nerve cells they contain a cell body, an axon, and dendrites the cell body is the part that contains the nucleus and cytoplasm the axon is a piece that extends from the cell body. The two main parts of the nervous system are the central nervous system and the peripheral (say per-if-er-al) nervous system how nerve cells work at the end of each nerve cell there is a synaptic terminal (say sin-ap-tik term-in-ul. Three main types of neurons that make up the neural layer (photoreceptors, bipolar cells and ganglion cells) are involved in generating action potentials (marieb and hoehn, 2011, p 552.

Tissue: tissue, in physiology, a level of organization in multicellular organisms it consists of a group of structurally and functionally similar cells and their intercellular material by definition, tissues are absent from unicellular organisms even among the simplest multicellular species, such as. Overview of neuron structure and function at the beginning of this article, we said that the nervous system was made up of two types of cells, neurons and glia, with the neurons acting as the basic functional unit of the nervous system and the glia playing a supporting role there are four main types of glial cells in the adult. The peripheral nervous system (pns) – made up of pairs of nerves that originate either from the brain or the spinal cord the peripheral nervous system this is divided into: • sensory neurons which carry impulses away from receptors to the cns • motor neurons which carry nervous impulses from the cns to effectors the spinal cord is a.
- nervous system the two types of the nervous system are the central nervous system and the peripheral nervous system they are responsible for integrating, processing, and coordinating sensory data and motor commands the central nervous system, which interprets sensory input and carry information to maintain homeostasis. Cells of the nervous system the nervous system is composed of only two main types of cells: neurons and cells that support the neurons, which are called glial cells neurons are the basic structural and functional units of the nervous system they are specialized to.
The one million millions of cells in a mammalian nervous system can be classified into 2 distinguishable classs the first being nerve cells, the primary communication cell within the nervous system that is responsible for relaying messages within the cardinal nervous system ( cns ) and for reassigning messages to cells in the fringe ( knott and molnar 2001 ). The three major types of cells in the blood are red blood cells, white blood cells, and platelets red blood cells determine blood type and are also responsible for transporting oxygen to cells white blood cells are immune system cells that destroy pathogens and provide immunity. In this nervous system lab, in this section of the lesson i explain to students that the nervous system is divided into two main subsystems, cns (central nervous system) and pns human body is a system of interacting subsystems composed of groups of cells ccc - systems and system models - systems may interact with other systems they.
