Step-by-step solution
Connective tissue consists of variously shaped cells lying in an extracellular material called matrix. It joins one tissue to another in the organs. Connective tissue is absent inside the central nervous system i.e. brain and spinal cord and thus has no function in the conduction of nerve impulse.The nerve cells of the brain and spinal cord are held together by supporting cells called neuroglia cells.
