Question

Which cells is nervous tissue made of?  How is the generic function of this tissue related to the characteristics of the main cell type that forms it?

Answer 1

Nervous tissue is the term for groups of organized cells in the nervous system, which is the organ system that controls the body’s movements, sends and carries signals to and from the different parts of the body, and has a role in controlling bodily functions such as digestion.Nervous tissue consists of two main types of cells;they are the neurons and neuroglia.

• Nerve cells, also written neurons transmit nerve impulses that move information around the body.
• Neuroglia are also known simply as "glia" and have various functions in support of nerve cells but do not transmit nerve impulses themselves.
• The function includes the membrane projection and elongation.
• Each neuron consists of an enlarged part called the cell body which contains of nucleus of the cell and many "processes" called dendrites that extend away from the cell body and are important because they receive the nerve impulses.
• They are not sensitive to stimuli and so do not generate or conduct nerve impulses. "Glia" or "Neuroglia" are therefore sometimes referred to as the "non-nervous cells of the nervous system".
