Tight junctions help to stop substances from leaking across a tissue.
Adhering junctions perform cementing to keep neighbouring cells together.
Gap junctions facilitate the cells to communicate with each other by connecting the cytoplasm of adjoining cells, for rapid transfer of ions, small molecules and sometimes big molecules.

It exerts the greatest control over the bodys responsiveness to changing conditions.
Chondrocytes, the unit of neural system are excitable cells.
Neuroglial cells protect and support neurons.
When a neuron is suitably stimulated, an electrical disturbance is generated.
