Define and differentiate the following:-
1) Neuron
2) Neural tissue
3) Neurolgia
4) Neuroglea
Answers
Answer:
Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system. ... Neurons have three basic parts: a cell body and two extensions called an axon (5) and a dendrite (3).
Explanation:
However, neurons differ from other cells in the body because: Neurons have specialize cell parts called dendrites and axons. Dendrites bring electrical signals to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process.
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. ... Nervous tissue also includes cells that do not transmit impulses, but instead support the activities of the neurons.
The main difference between nervous tissue and nervous system is that the nervous tissue is one of the four types of tissues in animals, making up the nervous system, whereas the nervous system is the complex system of nerves and cells, which coordinate the functions of the body in response to different responses.
Neuralgia is a stabbing, burning, and often severe pain due to an irritated or damaged nerve. The nerve may be anywhere in the body, and the damage may be caused by several things, including: aging.
The neuroglia are a diverse class of cells that provide developmental, physiological, and metabolic support for neurons. They are responsible for maintaining homeostatic control and immune surveillance in the nervous system.
The four types of neuroglia found in the central nervous system are astrocytes, microglial cells, ependymal cells, and oligodendrocytes. The two types of neuroglia found in the peripheral nervous system are satellite cells and Schwann cells. Neurons are the other the other type of cell that comprise nervous tissue.

Answer:
- Neuron:- Nerve cell
- Neural tissue:- Connected form of nerve cells / neurons
- Neurolgia:- Nerve tissue syste!
- Neurolgia and Neuroglea are similar structures.
