Question

Quizplus · Accepted Answer

The two main classes of cells in the nervous system are neurons and glial cells. Neurons are responsible for transmitting electrical and chemical signals, while glial cells provide support and protection to neurons. Dendrites and axons are both parts of neurons, and axons are a subset of neurons, so choices A and B are incorrect. Choice D is also incorrect, as dendrites are a type of neuron and not a separate class of cells.
