Glial cells provide protection and support for the neurons. This is why they are called "the supporting cells" of the nervous system. They act as insulation and provide structure to surrounding neurons.
Some protect the neurons from disease. Some can provide the insulation (white matter) along their axons, through differing mechanisms depending on the types. Astrocytes help regulate chemical environment and blood flow, schwann cells provide myelin sheaths (insulation) in the PNS, oligodendrocytes provide myelin sheaths in the CNS, and microglia act similarly to certain white blood cells.
The main cell types in nervous tissue are neurons and neuroglial cells. Neurons are responsible for transmitting electrical signals, while neuroglial cells support and protect neurons. Some examples of neuroglial cells include astrocytes, oligodendrocytes, and microglia.
Nervous tissue is composed of neurons and supporting cells called neuroglial. The neuroglial are unspecialized cells and are able to perform supporting functions unlike the neurons which are used in key functions.
Neuroglial cells, also known as glial cells, provide nourishment and protection for neurons. They support neurons by regulating their environment, insulating them, and assisting with their functions. Astrocytes, oligodendrocytes, and microglia are examples of neuroglial cells that play important roles in maintaining the health and function of neurons.
The main cell type found in nervous tissue is the neuron. Neurons are responsible for transmitting electrical signals within the nervous system and are specialized for communication through both electrical and chemical signals.
The most abundant cells and are responsible for protecting and supporting the neurons in transmitting cognitive/ sensory information, however do not actually conduct electrical impulses themselves.

Neurons are the basic structural unit of nervous system.But there are other cells called as neuroglial cells (comprise 50% of the total nervous system along with nerve cells) which are also the structural unit of nervous system.Neurons on the other hand are functional unit too but neuroglial cells are not.
Neuroglial cells provide support and protection for neurons in the central nervous system. They also help maintain the blood-brain barrier, regulate ion and neurotransmitter levels, and assist in repairing nervous tissue after injury.

One type of neuroglial cell not found in the central nervous system (CNS) is the Schwann cell. Schwann cells are responsible for myelinating peripheral nerves in the peripheral nervous system (PNS). In contrast, oligodendrocytes serve a similar function in the CNS by myelinating axons. Thus, while Schwann cells are crucial for peripheral nerve function, they do not exist in the CNS.
