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 process viz dendron and axon and form synapse. On the other hand, neuroglia possess only one type of processes and do not from the synapse. Majority of neurons are not capable of differentiating and multiplying in the mature nervous system whereas neuroglia can multiply themselves.

Difference Between Neurons And Neuroglia

Properties Neurons Neuroglia
Define 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 synapsis Yes No
Number 100 billion Around 5-10 times the neurons in higher vertebrates
Age & number The number does not change 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
