What are the parts of the nervous system? The basic working unit of the nervous system is a cell called a neuron. The human brain contains about 100 billion neurons. A neuron consists of a cell body containing the nucleus, and special extensions called axons (pronounced AK-sonz) and dendrites (pronounced DEN-drahytz).

- Symptoms: Peach trees with X-disease usually appear normal at the start of the growing season although some trees may exhibit branch and twig dieback due to increased sensitivity to winter injury or may have slightly smaller leaves. However, by mid-summer, there is a fairly sudden and dramatic onset of symptoms.

Nervous tissue It is composed of neurons, or nerve cells, which receive and transmit impulses, and neuroglia, also known as glial cells or more commonly as just glia (from the Greek, meaning glue), which assist the propagation of the nerve impulse as well as providing nutrients to the neuron.tructure [edit]. Nervous tissue is composed of neurons, also called nerve cells, and neuroglial cells. Typically, nervous tissue is categorized into four types of tissue. In the central nervous system (CNS), the tissue types found are grey matter and white matter.

Physiological Psych 2200 A clump of neuron cell bodies, for example, is called a ganglion (plural: ganglia) or a nucleus (plural: nuclei). A fiber made up of many axons is called a nerve. In the brain and spinal cord, areas that are mostly axons are called white matter, and it is possible to differentiate pathways or tracts of these axons.here are estimated to be as many as 100 billion neurons in our nervous system! A typical neuron has all the parts that any cell would have, and a few specialized structures that set it apart. The main portion of the cell is called the soma or cell body.

- Here are some examples of nervous tissue: 1  Gray matter-cells without insulation, tightly packed in your brain and in the inner part of your spinal cord. 2  White matter-cells insulated by a substance called myelin. 3  Neuroglial cells-these cells support and nourish the nerve cells.he nervous system is not just built from neurons. There are also cells that don't communicate, but wrap around the neurons to nourish and protect them, called Schwann cells. The organs of the nervous system work together to coordinate body processes.

A cell that carries information through your nervous system is called...? Types of Neurons (Nerve Cells). The human body is made up of trillions of cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry messages through an electrochemical process. The human brain has approximately 100 billion neurons.To learn how neurons carry messages, read about the action potential.Remember that 1 micron is equal to one thousandth of a millimeter!). Neurons are similar to other cells in the body because: 1  Neurons are surrounded by a cell membrane. 2  Neurons have a nucleus that contains genes. 3  Neurons contain cytoplasm, mitochondria and other organelles.

Nervous System: Facts, Function & Diseases The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.ccording to the National Institutes of Health, the central nervous system is made up of the brain, spinal cord and nerves. The peripheral nervous system consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect to one another and to the central nervous system.

Physiological Psych 2200 This nervous system is composed of billions of cells, the most essential being the nerve cells or neurons. There are estimated to be as many as 100 billion neurons in our nervous system! A typical neuron has all the parts that any cell would have, and a few specialized structures that set it apart. The main portion of the cell is called the soma or cell body. It contains the nucleus, which in turn contains the genetic material in the form of chromosomes. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body.

What are the parts of the nervous system? The nervous system consists of two main parts: the central nervous system and the peripheral nervous system: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of the nerve fibers that branch off from the spinal cord and extend to all parts of the body, including the neck and arms, torso, legs, skeletal muscles and internal organs. The brain sends messages through the spinal cord and nerves of the peripheral nervous system to control the movement of the muscles and the function of internal organs. The basic working unit of the nervous system is a cell called a neuron.

What is Myelin? Each neuron is made up of a cell body and an axon (the extension of the cell body that carries messages). Most of the axons in the central nervous system are wrapped in myelin, a substance rich in lipids (fatty substances) and proteins.yelin is present in the central nervous system (CNS) and peripheral nervous system (PNS); however only the central nervous system is affected by MS. CNS myelin is produced by special cells called oligodendrocytes. PNS myelin is produced by Schwann cells.
