Neurons communicate with each other via 'synapses'. Let us consider an example of how this works. Say a neuron becomes excited because its antennae, which are called 'dendrites', have just received a number of inputs from neighbouring neurons. Say as a result of this it now 'fires an action potential'. This will involve a electrical pulse being sent from its cell body (the soma) all the way down its axon to the very end - the 'axon terminal'. This terminal has two main characteristics: 1) it stores and releases neurotransmitters; and 2) it comes into close apposition (not quite physical contact) with some process of another cell, usually a point on a dendritic branch (antenna). The tiny gap between the axon terminal and the recipient cell is called a synapse, or 'synaptic cleft'. As soon as the electrical impulse reaches the terminal, neurochemicals will be released into the synaptic cleft where they will diffuse a very short distance and bind to 'post-synaptic receptors' on the recipient cell's dendrite (or in some cases, its cell body). These chemicals are the 'inputs' that were referred to in the beginning of this example. And on and on it goes. The synapse is the point of exchange - the neurochemicals are the messengers. by sending signals

How fast does information travel through the nervous system?
ok
How does information travel from one part of the body to another?
with the help of nerves and nervous system
In the book the pearl why is the town like a nervous system?
The town in "The Pearl" by John Steinbeck is compared to a nervous system because news and gossip travel rapidly through its inhabitants, just like how impulses travel through a nervous system. It highlights the interconnectedness of the community and how quickly information can spread.
What body system processes and analyzes information?
The central nervous system processes and analyses information.
What are two main jobs of the nervous system?
The nervous system takes in sensory information from the peripheral nervous system. This information is then directed to the central nervous system which then responds with a motor reaction that travels back to the peripheral nervous system.
What body system stimulates muscles to contract and interprets information from sensory organs?
The nervous system which also interprets information from sensory units
Which nervous system receives information from sense organs and analyzes that information.?
the central nervous system
What nervous system transmits information to voluntary muscles while the?
It is the somatic nervous system that transmits information to voluntary muscles. The autonomic nervous system transmits information to involuntary muscles.
What is the bodys speedy electrochemical information system called?
the nervous system.
What Cells carry information through your nervous system?
what is the name given to the cell that carry message though the nervous system
What the peripheral system do?
Peripheral System is a division of the Nervous System. They have 2 types of cells. The sensory nervous cells carry information to the central nervous system; and the motor nervous cells carry information from the central nervous system. The Peripheral System is also divided into the somatic nervous system (controls the voluntary muscles) and the automatic nervous system (controls involuntary muscles).
