Factual and Proximate Cause
Types of Neurons (Nerve Cells). The human body is made up of trillions of cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry messages through an electrochemical process. The human brain has approximately 100 billion neurons.To learn how neurons carry messages, read about the action potential.owever, neurons differ from other cells in the body because: 1  Neurons have specialize cell parts called dendrites and axons. 2  Neurons communicate with each other through an electrochemical process. 3  Neurons contain some specialized structures (for example, synapses) and chemicals (for example, neurotransmitters).
A human body is made up f number of cells. A nerve cell is defined as the cells of nervous system, which controls all types of body activities. The nerve cells are specialized cells, which transmits message from one part to another part of the body. Motor nerve cell 0 - The nerve cell that passes the instructions from our central nervous system to other parts of our body. 2  For example â to muscles or to our glands. 3  Association nerve cell-The nerve cell, which connects to our sensory and motor neurons.
