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).
Search term. Despite the specific molecular, morphological, and functional features of any particular nerve cell type, the basic structure of neurons resembles that of other cells. particularly salient morphological feature of most nerve cells is the elaborate arborization of the dendrites (also called dendritic branches or dendritic processes) that arise from the neuronal cell body.
