Explain how neurons and neuroglia are functionally different.
Homework Answers
ANSWER :
However, both the neurons and neuroglial cells are the majorly found in the nervous system but there are some functional difference between them such as neurons perform neural transmission via generating action potential while neuroglia cannot generate the action potential and never take part in transmission of nerve impulses. They mainly perform the function of providing support via producing myelin sheath and nutrition to the neurons.

UNIT Section Date REVIEW Check Your Understanding Critical Thinking and Application Questions 1 Neurons are amitotic, which means that after a certain stage, they do not divide further. Most tumor cells are characterized by a rapid rate of mitosis. Considering this, of which cell types (neurons or neuroglia) must brain tumors be composed? Why? 2 You are examining a neuronal process and you find that it generates action potentials. Is this an axon or a dendrite? How can you tell?...
