Difference Between Neurons And Neuroglia

The nervous system of higher vertebrates is made of two types of cells namely neuroglia (supporting cells of neurons) and neurons (signal transduction in the nervous system).

Neurons have two types of processes, viz, dendrons and axons, and forms synapse. On the other hand, neuroglia possesses only one type of process and do not from synapse. Majority of neurons are not capable of differentiating and multiplying in the mature nervous system whereas neuroglia can multiply themselves.

Neurons vs Neuroglia

Following are the important difference between neurons and neuroglia:

Neurons Neuroglia
Definition
They receive and transmit nerve impulses
They provide mechanical as well as structural support to the neurons
Granules
Nissl’s granules No granules
Formation of synapse
Yes No
Number
100 billion
Around 5-10 times the neurons in higher vertebrates
Age & number
The number does not change with age
The number decreases with age
Size
4 micrometer to 1 millimeter
Smaller than neurons
Axons
Present Absent
Function
It involves itself in signal transduction
Supplies nutrients to neurons
Referred as
The functional unit of the nervous system
They are supporting cells of neurons

What are Neurons?

Neurons are the structural and functional unit of nervous system. They help in the conduction of nerve impulse. Neurons are made up of three main parts – axon, dendrites and cell body. Sensory neurons carry information from the sensory receptors and transmit it to the brain. The motor neurons transmit information from the brain to the body.

What are Neuroglia?

Neuroglia are non-neuronal cells that support and protect the neurons. Neuroglia in the central nervous system include astrocytes, oligodendrocytes, microglial cells, and ependymal cells. Schwann cells and satellite cells are the neuroglia in the peripheral nervous system.

Neurons are the structural and functional unit of nervous system. They help in transmitting the nerve impulse. Neuroglia are the supporting cells. Neurons are like the communication network of the body whereas neuroglia facilitates the functioning of the communications network.
