Presentation transcript:

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 body (soma) that conducts nerve impulses away from the cell body to the neuron's terminal buttons. Dendrite - Is the tree branch like structure connected to the nerve cell body (soma) that sends and receives information between cells. Can be thought of as the brain's traffic cops routing messages to their desired cell target futurity.org

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 the-neuron/

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. ieaecell.org
