Neurons vs. Neuroglia: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Neurons are the primary cells of the nervous system, transmitting signals, while neuroglia support, protect, and nourish neurons.
Key Differences
Neurons are specialized cells in the nervous system responsible for transmitting electrical and chemical signals, fundamental for brain and nerve function. Neuroglia, in contrast, play a supporting role, aiding in the maintenance, protection, and support of neurons.

Neurons have a unique structure with dendrites, a cell body, and an axon to facilitate signal transmission. Neuroglia do not have such specialized structures, as their primary role is to provide support and insulation for neurons.

There are various types of neurons, including sensory, motor, and interneurons, each with specific functions. Neuroglia also come in different types, such as astrocytes, oligodendrocytes, and microglia, each serving different supporting roles.

Neurons generally do not replicate or regenerate after being fully developed, making them more vulnerable to damage. Neuroglia can proliferate and repair themselves, thereby playing a crucial role in the healing and maintenance of the nervous system.

Neurons interact directly with other neurons or muscle cells, transmitting impulses for bodily functions. Neuroglia, while they do not transmit impulses, interact with neurons to provide metabolic support, waste removal, and structural stability.

Neuroglia
The supportive tissue of the nervous system, including the network of branched cells in the central nervous system (astrocytes, microglia, and oligodendrocytes) and the supporting cells of the peripheral nervous system (Schwann cells and satellite cells). Also called glia.

Neuroglia
The delicate connective tissue framework which supports the nervous matter and blood vessels of the brain and spinal cord; called also Kölliker's reticulum. It is composed of cells which are not neurons. Once thought to serve merely a supporting funciton, they are now believed to have important metablolic functions. Among them are the astrocytes, ependymal cells, oligodendroglia cells, and microglia cells.
