What are the neurons of the nervous system?

Neurons (=nerve cells) are the structural and functional unit of the neural tissue and hence the nervous system. Certain neurons may almost equal the length of the body itself. These neurons with longer processes (projections) are the longest cells in the body. Human neural system has about 100 billion neurons. Majority of the neurons occur i the brain. Fully formed neurons never divide and remain in the interphase throughout life. Shortly after birth, new neurons dont develop. Certain neurons have flask shaped cytons (cell body or soma) and are called Purkinje cells, which occur in the cerebellum of the brain.


What is the difference between neurons and neuroglia?

Neurons conduct electrical impulses in the brain. Neuroglia are cells that support the neurons. These cells undergo mitosis where neurons do not. Brain tumors are formed from neuroglia cells because they mitosis.
