Transcript Neurons

A neuron is the functioning cell unit in the
nervous system that is also known as a nerve
cell. Neurons are responsible for sending
impulse messages to other neural cells. Impulse
messages in a neuron are sent via the release of
neurotransmitters. The neuron's cell body is
called the soma. The neuron cell consists of 3
main sections a soma, axon, dendrite.

Axon - Is the lengthy thin straight
structure that is part of the neuron

the nerve cell

Can be
thought of as

Dendrite -
the structural space
between neurons in
the nervous system
that is the conduit
for a neuron to
send a chemical
message signal to
the targeted neural
cell. A synapse is
also known as the
terminal button
Synapse -. Once a message is
received at the postsynaptic
cell an electrical message is
released and passes through
the adjoining neuron to the
next pre-synaptic cell that
releases another chemical
message. The process will
repeat it self until the
message reaches it desired
target. The word synapse is
Greek in origin and means
point of contact

Neuron Forest
 The real work of your brain goes on in individual
cells. An adult brain contains about 100 billion nerve
cells, or neurons, with branches that connect at more
than 100 trillion points. Scientists call this dense,
branching network a "neuron forest.“
 Signals traveling through the neuron forest form the
basis of memories, thoughts, and feelings

The Epileptic Focus
The place from where the seizure originates is
called the epileptic focus. Neuron cells in this area
tend to be electrically unstable. At any given time,
some neuron cells are firing; others are getting
ready to fire while still others are resting. During a
seizure a large group of neuron cells start firing all
at once. When a large group of unstable neurons
start firing all at once, it causes the next group of
neurons to fire, which has the same effect on the
next and so on. This results in a seizure.
