Nerve Cells and Neurotransmission Instead, communication between nerve cells occurs mainly through the release of chemical substances into the space between the axon and dendrites (Figure 5). This space is known as the synapse. When neurons communicate, a message, traveling as an electrical impulse, moves down an axon and toward the synapse.

- Your nervous system contains millions of nerve cells, called neurons. Neurons are highly specialised to transmit messages from one part of your body to another. All neurons have a cell body and one or more fibres. These fibres vary in length from microscopic to over 1 metre. There are two different kinds of nerve fibres: fibres that carry information towards the cell body, called dendrites, and fibres that carry information away from it, called axons.

Myelin: A Specialized Membrane for Cell Communication Depending on the location, different glial cell types make myelin in a different manner. Schwann cells make myelin in the peripheral nervous system (PNS: nerves) and oligodendrocytes in the central nervous system (CNS: brain and spinal cord). In the PNS, one Schwann cell forms a single myelin sheath (Figure 1A).he nervous system is comprised of two primary cell types: neurons and glial cells. These cells communicate with each other to perform important tasks in the nervous system. The glial cells support neurons structurally and maintain their long-term neuronal integrity, and neurons regulate glial cell behavior.

Neuron These signals between neurons occur via synapses, specialized connections with other cells. Neurons can connect to each other to form neural networks. Neurons are the core components of the brain and spinal cord of the central nervous system (CNS), and of the ganglia of the peripheral nervous system (PNS).ynaptic signals from other neurons are received by the soma and dendrites; signals to other neurons are transmitted by the axon. A typical synapse, then, is a contact between the axon of one neuron and a dendrite or soma of another.

- Nerve Communication. Potassium in your nerve cells, or neurons, aids in communication. Normally, your neurons maintain a resting state -- a constant electrical charge relative to their surroundings -- in which they contain high levels of potassium and low levels of sodium.

- Axons make contact with other cells—usually other neurons but sometimes muscle or gland cells—at junctions called synapses. At a synapse, the membrane of the axon closely adjoins the membrane of the target cell, and special molecular structures serve to transmit electrical or electrochemical signals across the gap.n axon is one of two types of protoplasmic protrusions that extrude from the cell body of a neuron, the other type being dendrites.

Neuron The neuron (nerve cell) is the fundamental unit of the nervous system. The basic purpose of a neuron is to receive incoming information and, based upon that information, send a signal to other neurons, muscles, or glands. Neurons are designed to rapidly send signals across physiologically long distances. They do this using electrical signals called nerve impulses or action potentials. When a nerve impulse reaches the end of a neuron, it triggers the release of a chemical, or neurotransmitter. The neurotransmitter travels rapidly across the short gap between cells (the synapse) and acts to signal the adjacent cell.

- Nerves. Nerves are bundles of axons in the peripheral nervous system (PNS) that act as information highways to carry signals between the brain and spinal cord and the rest of the body. Each axon is wrapped in a connective tissue sheath called the endoneurium.he nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.

- Synaptic Transmission. Introduction Neurons receive information from sensory organs, send information to motor organs, or share information with other neurons. The process of communicating information is very similar, whether it is to another neuron or to a muscle or gland cell.he transmission of information is accomplished in two ways: 1  Electrically: the neuron is directly adjacent to other neurons. 2  Chemically: there is a space (the synaptic cleft) between the axon terminus and the adjacent neuron.

Neurons and electrochemical transmission Neurons and electrochemical transmission. The body’s ability to transmit electrical signals relies on a special type of cell called a neuron. As we’ll see, neural communication actually involves both electrical and chemical—or electrochemical—communication. To understand this process, there are five parts of the neuron that you’ll need to know: The dendrites, soma, axon, axon hillock, and terminal buttons, as shown in Figure 12.1.

- Nerve cells are very variable in appearance, but all neurons have a cell body, also called soma or perikarion, and processes. The cell body contains the nucleus and organelles that maintain the nerve cell.The processes extend from the nerve cell to communicate with other cells.ervous tissue consists of nerve cells and associated supporting cells. All cells exhibit electrical properties, but nerve cells, also called neurons, are specifically designed to transmit electrical impulses from one site in the body to another, and to receive and process information.

Neurons and Their Role in the Nervous System Neurons have a membrane that is designed to send information to other cells. The axon and dendrites are specialized structures designed to transmit and receive information. The connections between cells are known as synapses. Neurons release chemicals known as neurotransmitters into these synapses to communicate with other neurons.

Understanding Nerves and Neurons Impulses can travel faster along neurons that have a myelin sheath as an impulse can jump from node to node. What do nerves do? All nerves have two main functions, these are: Receive signals: Nerves receive signals because they are irritable, meaning that they can respond to a stimulus. Transmit nerve impulses: Nerves are able to transmit impulses along the length of the nerve cell in the form of an electrical signal (like power lines). These electrical signals move from one end of the nerve cell to another and can pass from nerve to nerve (power pole to power pole).

- Most cells, however, communicate via chemical synapses. Such cells are separated by a space called a synaptic cleft and thus cannot transmit action potentials directly. Instead, chemicals called neurotransmitters are used to communicate the signal from one cell to the next.

An Overview of the Different Parts of a Neuron Neurons are the basic building blocks of the nervous system. These specialized cells are the information-processing units of the brain responsible for receiving and transmitting information. Each part of the neuron plays a role in communicating information throughout the body. Neurons carry messages throughout the body, including sensory information from external stimuli and signals from the brain to different muscle groups in the body. In order to understand exactly how a neuron works, it is important to look at each individual part of the neuron.
