What are the two main types of cells in the nervous system?

The two main types of cells in the nervous system are neurons and glia. Neurons are the primary functional cells responsible for transmitting and processing information through electrical and chemical signals. They play a crucial role in communication within the nervous system, allowing responses to stimuli and facilitating complex behaviors and functions. Glia, or glial cells, support the neurons in various ways, such as providing structural support, insulation, and nourishment, as well as contributing to the maintenance of the chemical environment of the nervous system. Together, neurons and glia work in harmony to ensure that the nervous system operates effectively and efficiently. This distinguishes them clearly from the other options, which do not pertain to the nervous system.
