A neuron is an electrically excitable cell that processes and transmits information through electrical and chemical signals.
A neuron consists of a cell body (perikaryon) and its processes, an axon and one or more dendrites. Neurons function in the initiation and conduction of impulses. They transmit impulses to other neurons or cells by releasing neurotransmitters at synapses. 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. 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. Neurons come in many different shapes and sizes. A neuron (/ˈnjʊərɒn/ NYEWR-on or /ˈnʊərɒn/ NEWR-on; also known as a neurone or nerve cell) is an electrically excitable cell that processes and transmits information through electrical and chemical signals. These signals between neurons occur via synapses, specialized connections with other cells. A typical neuron consists of a cell body (soma), dendrites, and an axon. The term neurite is used to describe either a dendrite or an axon, particularly in its undifferentiated stage. Neuron. A neuron is a nerve cell. Neurons send information to and from your brain to the rest of your body. A neuron is made up of: 1  A cell body. 2  This is where the nucleus is. 3  Dendrites. 4  The dendrites receive signals from other neurons. 5  A long, thin axon. 6  The axon is covered by a myelin sheath. 7  The axon passes information to the next neuron or other cell in the body. 8  A
