Answer:
The cell that is central to the nervous system, and accounts for just about every cell in the nervous system, is the Neuron.
Step-by-step explanation:
- The nervous system is composed of two types of cell; the glial cells and the neurons.
- Among these two, the neurons are central to the nervous system because the are the functional units of the system
- Glial cells are supportive in function.
- The conduction of nerve impulse is carried out by neurons while the glial cells nourish and insulate the neurons.
- The neurons are incapable of division so once the neurons are damaged they are not replaced by new neurons.
- However the glial cells are capable of division and the voids created due to the damage to the neurons are filled up by the glial cells.
