Question

Are neurons the structural and functional units of the nervous system, whereas neuroglial cells are accessory cells in nerve tissue?

Answer 1

Neuroglial cells or glial cells deliver supporting functions to the nervous system. Initial research observed glial cells as the “glue” of the nervous system. But experts are now progressively distinguishing the crucial role glial cells play in brain function and development. Glia, also named as glial cells or neuroglia are non-neuronal cells in the central nervous system or CNS (CNS refers to brain and spinal cord) and the peripheral nervous system or PNS that do not produce electrical impulses.

Complete Answer:
An infant arrows in front of your bike as you race down the street. You see the child and rapidly react. You hold the brakes, keep away from the child and yell out a warning. All in just seconds. How can you respond so quickly? Such quick responses are organized by your nervous system. The nervous system is a complex network of nervous tissue that transmits electrical communications throughout the body. It includes the brain and spinal cord, the central nervous system, and nerves that run throughout the body, the PNS. To comprehend how nervous messages can travel so rapidly, we need to distinguish more about nerve cells.
Though our nervous system is very complex and nervous tissue contains just two basic kinds of nerve cells: neurons and neuroglia or glial cells. Neurons are the structural and functional components of our nervous system. They communicate through electrical signals called nerve impulses. Neuroglial cells deliver support for neurons. For example- they offer neurons with nutrients and other resources.

Note:
Neurons are the structural and functional components of our nervous system. They contain a cell body or soma, axon and dendrites. Neurons convey nerve impulses to other cells. Types of neurons comprise sensory neurons, motor neurons, and interneurons. They sustain homeostasis, form myelin in the peripheral nervous system and deliver support and defence for neurons.
