Ten Mind-amplifying Facts About Neurons

, , Leave a comment


1. Neurons are the cells of the nervous system.
• Neurons and glia are the two major cells that make up the entire nervous system which works as networks.
• Neurons, the basic unit of the brain serves as messengers inside the body through the process of neurotransmission.

2. Neurons in the brain alone are approximately 200 billion.
• Furthermore, these neurons have about 10,000 specific types.
• Their accumulated tasks and complexities of mechanisms is what make human functions.

3. Neuron loses account about a million every year or two.
• Whether you like it or not, everyone is entitled to neuron loss.
• No worries, these won’t cause any significant trouble because the brain has the power to grow new ones.

4. Neurons are different from other cells in the body.
• Though, technically they are similar from other cells in the body because they have organelles too), its dendrites and axons set it apart.
• Dendrites which are branches-like spike extensions of the cell body that carry electrical impulses to the cell body while axons bring information away from the cell body.
• They also have specialized structured connections called the synapses. This structure is the path neurons follow to convey information from one neuron to another

5. Neurons send information in different directions.
• These are sensory (afferent neurons) processes sensory inputs stimulating the human senses;
• Motor (efferent neurons) processes motor information that enables a person to move and;
• Interneurons, which connects neurons to neurons.

6. Neurons are electrically excitable.
• Just like how electric current flows to household circuits and ignite electricity to have all the appliances working. They have insulators too which is the myelin sheath of the axons of a neuron.
• Their basic stimuli and mode of communication is generated through electrochemical processes.
• In neurons this is called synaptic signal transmission.

7. Neurons, FYI they are the oldest cells known to exist inside the body.
• Cells in the body have different life span.
• Neurons particularly of the cerebral cortex can last a lifetime followed by the cells of the eyes and cardiac muscle cells.

8. Do you know that Neurons process information far greater than the number of stars in the galaxy?
• Yes, you heard it right. There are too numerous ways on how they relay inputs and produce outputs in the entire nervous system.
• Neurons are longest cell types in the body.
• There are trillions of neurons in the body and try to imagine a single neuron is further connected between 5,000 to 200,000 other neurons. Do the math, it’s quite challenging.

9. Neurons of a baby’s brain are approximately 100 billion.
• Through social interactions as the baby grows, these neurons rapidly make connections that further contribute to the baby’s brain development.
• Positive emotional interactions are necessary for a healthy brain in infancy.

10. Neurons decreases in number as the person ages.
• Age is one of the factors that contribute to degeneration of neurons.
• Most of the neurons do age too and results in structural changes of the brain.
• As individuals get older even healthy ones, their neurons gets overused, exhausted and die.
• In fact, about a thousand of neuron loss is inevitable every day.
• Neurons are responsible for the higher level of functioning in humans. They take charged cognitive information that processes everything else that has something to do with the mind (thinking, reasoning, emotions).
• This could explain why older people tend to have mild slowing of mental and cognitive functioning which is why it is recommended to institute supplemental support for brain nourishment.
