GLIAL CELLS:
- They are the secondary supporting cells which are involved in the regulation of homeostasis of the nervous system and protection.
- These cells have only one processes i.e., axons and Nissl granules are absent , but have dendrites.
- They have the ability to undergo cell division with age.
- Glial cells cannot generate action potential but have a resting potential.
- glial cells do not have chemical synapses.
NEURONAL CELLS:
- Neurons are the basic structural units which are involved in the transmission of impulses throughout the body during coordination of voluntary and involuntary actions.
- These cells have two processes. one axon and one dendrite. And Nissl granules are also present.
- They lack the ability of regeneration and are non-renewable and keep to their original form till death.
- Neurons can generate an action potential.
- Neurons have synapses that uses neurotransmitters.
