Electrical events propagate a signal within a neuron, and chemical processes transmit the signal from one neuron to another or to a muscle cell. The chemical process of interaction between neurons and between neurons and effector cells occur at the end of the axon, in a structure called synapse. The transfer of information from neuron to neuron takes place through the release of chemical substances into the space between the axon and the dendrites. These chemicals are called neurotransmitters, and the process is called neurotransmission. The space between the axon and the dendrites is called the synapse. The brain is the body's control centre: it sends messages to your body through a network of nerves called “the nervous system”, which controls your muscles, so that you can walk, run and move around. Nerve cells communicate by using electrical signals. Nerve cells communicate by using electrical signals. Dendrites, the widely branched portion of the neuron, receive signals from other neurons and then transmit them over a thin cell extension -- the axon -- to other nerve cells. Neurons allow the body to communicate. In understanding the biological bases of behavior it is important to gain an understanding of neurons and neurotransmitters. The neuron is composed of three main parts: axon, cell body and dendrites.

Neurons are divided into four major types: unipolar, bipolar, multipolar, and pseudounipolar. Unipolar neurons have only one structure extending from the soma; bipolar neurons have one axon and one dendrite extending from the soma.

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 86 billion neurons. To learn how neurons carry messages, read about the action potential.

Information travels at different speeds within different types of neurons (nerve cells). Signals can travel as slow as about 1 mph or as fast as about 268 mph.

Two types of phenomena are involved in processing the nerve impulse: electrical and chemical. Electrical events propagate a signal within a neuron, and chemical processes transmit the signal from one neuron to another or to a muscle cell.

For the spinal cord though, we can say that there are three types of neurons: sensory, motor, and interneurons. Sensory neurons. Motor neurons. Interneurons. Neurons in the brain.

Myelinated neurons are typically found in the peripheral nerves (sensory and motor neurons), while non-myelinated neurons are found in the brain and spinal cord. Dendrites or nerve endings.

Integration is the process of combining information from many sources. The nervous system can do this, because neurons (nerve cells) have a part (called dendrites), which are designed to combine or integrate information. They get connections, called ( synapses) from many other neurons and combine the signals from them.

The brain is a mosaic made up of different cell types, each with their own unique properties. The most common brain cells are neurons and non-neuron cells called glia. Although neurons are the most famous brain cells, both neurons and glial cells are necessary for proper brain function.

Cells communicate through their own language of chemical signals. Different compounds, such as hormones and neurotransmitters, act like words and phrases, telling a cell about the environment around it or communicating messages.

How muscle cells communicate with the nerve cells that control them is one of the most-studied aspects in cell biology. Transmission of electrical signals at the synapse results from the release of acetylcholine from the neuron that then binds to acetylcholine receptors located on the surface of the muscle cell.

The brain works like a big computer. It processes information that it receives from the senses and body, and sends messages back to the body. Brain tissue is made up of about 100 billion nerve cells (neurons) and one trillion supporting cells which stabilize the tissue.

- Blows to the brain, or the damage caused by a stroke, can kill neurons outright or slowly starve them of the oxygen and nutrients they need to survive. These neurons may still live, but they lose their ability to communicate. One method of cell death results from the release of excess glutamate.

The human brain is believed to function in a complex chemical environment through various types of neurons and neurotransmitters. Neurons are brain cells, numbering in the billions, which are capable of instant communication with each other through chemical messengers called neurotransmitters.

Dendrites are like mini-computers in your brain. The branch-like projections of neurons called dendrites are not just passive wiring, but act more like tiny computers, multiplying the brain's processing power.
