Cells in the Brain

Neurons are clearly differentiated by their way to communicate and interact with other cells through electrical and chemical signaling. They come in many different morphologies. This is determined by their tails, nucleus, and branches. Axons are the long  hot dog bun connected body of the Neuron.Dendrites are the branches which come off the end of the axons known as terminals. Dendrites are used for signaling in a process called synapses. Synapses helps convey information from neuron to neuron in a nerve. At the end of each dendrite is a synapse.

  

    This synapse will meet with others from different neurons to continue a message towards or from the Central Nervous System (CNS). Axons are the tails of neurons. On one side of them is the big circle where the neurons and axons exist. On the other side is the axon ending. There are 100 billion neurons existing in the human brain. The amount of information that 1 neuron took in its life time is measured in converge. And the amount of information 1 neuron sent in life is divergence.

    Glial cells out number neurons 3:1. The word Glial comes from the Greek word Glia or glue. This is because the Greeks thought Glial cells hold the nervous system together. Although they have large numbers they do not interact with electrical or chemical signaling or synapses. The purpose of Glial cells is for helping in recovery such as concussions, speeding up signaling, or cleaning wounds, all depending on what Glial cell type they are..

Different types of Glia include

Oligodendrocytes- Only found in the CNS. Lay a layer of lipids called Myelin to speed up electrical signaling and synapses of neurons.

Schwann cells- Only found in PNS also lay Myelin in nerves.

Microglia- Remove debris from injuries in normal cells.
