Question

what is neuron detail explanation and 20 examples

Answer 1

Neurons, also known as nerve cells, send and receive signals from your brain. While neurons have a lot in common with other types of cells, they’re structurally and functionally unique.

Specialized projections called axons allow neurons to transmit electrical and chemical signals to other cells. Neurons can also receive these signals via rootlike extensions known as dendrites.

At birth, the human brain consists of an estimated 100 billion neurons. Unlike other cells, neurons don’t reproduce or regenerate. They aren’t replaced once they die.

The creation of new nerve cells is called neurogenesis. While this process isn’t well understood, it may occur in some parts of the brain after birth.

As researchers gain insight into both neurons and neurogenesis, many are also working to uncover links to neurodegenerative diseases such as Alzheimer’s and Parkinson’s.
