Question

Q= explain why there have to be two kinds of nerve cell
Q=what is difference between a nerve and a neurone
Q= suggest why a nerve has fatty insulation around it ​

Answer 1

Answer:

1.Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the "conducting" cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.

2.Neuron is an individual specialized cell which are primarily involved in transmitting information through electrical and chemical signals. They are found in the brain, spinal cord and the peripheral nerves. ... Nerve is an enclosed, cable-like bundle of axons and nerve fibers found in the peripheral nervous system.

3.Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells. If myelin is damaged, these impulses slow down.

Answer 2

Answer:

Most neurons have several dendrites and one axon. Because of their multiple processes, these are termed multipolar neurons. Simpler unipolar (one-process) and bipolar (two-process) neurons are much less common in vertebrate than in invertebrate nervous systems
