The neuron is a particular cell that has the ability to process and transmit information through either chemical or electrical signals. Neurons can be found throughout the animal kingdom, from small roundworms containing around 300 nerves in their entire nervous system, to humans with over eighty six billion neurons. In the human body, nerves can be found in the central nervous system (CNS) which consists of the brain and the spinal cord, which then attaches to the peripheral system, a system which is comprised of ganglia, a group of nerve cells, and the cells found in the ganglia are known as ganglion cells. Examples of these are the Retinal ganglion cells which contain specialised sensory neurons known as photoreceptors, which give us the…show more content…
A chemical synapse can be defined as synapses with synapses what convert the electrical energy from the pre synaptic neuron, and release it through either a neurotransmitter or a neuromodulator. In comparison to electrical synapses, chemical synapses have more complex mechanisms which require more time in order to perform a synaptic transfer, but because of this, they can have much more complex signals which are necessary for complex species such as humans. A chemical synapse begins transforming its action potential into chemical energy when the action potential causes the vesicles to release the neurotransmitters inside by exocytosis. Exocytosis is an energy demanding process which consists of the moving the vesicles, to the end with the vesicles contents being released. The first process consists of moving the vesicles, where they move depends on their purpose. The next part is tethering the vesicle to a membrane surface which eventually leads to the vesicle fusion. (Cram", 2012) This Part is drive by a protein known as “SNARE” proteins which have the function of acting as moderates for vesicle fusion. This protein is susceptible to the neurotoxins (Tetanospasmin) responsible for the common known disorder of tetanus, a condition which has the main feature of protract contraction of skeletal muscle tissue.

    What is a Synapse you may ask? Neurons have dendrites and axons. They each have a job; dendrites bring information to the cell body and axons take information away from the cell body. The synapse is where nerve impulses are transmitted and received. A synapse contains of a presynaptic ending that contains neurotransmitters such as mitochondria and other cell organelle, a postsynaptic ending that contains receptor sites for neurotransmitters, they use the neurotransmitters to communicate. An electrical
