Brain cells, or neurons, are what keep you alive, breathing, moving, talking, seeing, and thinking. It is hard to believe that these tiny cells sending electro-chemical signals do so much but they do, here is how.
Neurons are similar to other cells in the body but differ in these ways.
• Dendrites: Receive Chemical signals and convert into an electrical signal
• Cell body(soma): Contains Nucleus and other organelles Axon: channels electric signal to Presynaptic Terminal
• Presynaptic terminal: receives electric signal from the axon and releases neurotransmitters into synaptic cleft to trigger electric signal in the next cells dendrites
• Myelin: insulates the electric signal while it travels down the axon.
Neurotransmitters are chemicals contained in neurons that communicate information throughout the brain.
Here is a chart that explains what they do and what happens when you have and excess or a deficiency of these chemicals.
