While the four system approach to negligence is helpful in identifying whether or not an injury warrants legal action, it does fail to distinguish between two distinctly important concepts in the cause/effect relationship of negligence: factual causation vs. proximate cause. 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).
Neurons are the specialized cells in the central nervous system. Neurons are classified according to structure, shape and function. Each type of neuron has a specific role for the proper functioning of the brain and the spinal cord.ultipolar neurons are the dominating neurons in vertebrates in terms of number. These neurons are the ones that are the closest to the model neuron that we usually see in neuron structure diagrams. Each of them has a cell body, a long axon, and short dendrites.
