Verified step by step guidance

Understand the basic characteristics of neurons. Neurons are specialized cells in the nervous system responsible for transmitting information through electrical and chemical signals.

Recognize that neurons have the ability to generate action potentials. This is a fundamental characteristic that allows neurons to communicate with other neurons, muscles, and glands.

Identify that neurons have a high metabolic rate. This is due to their constant activity and the energy required to maintain ion gradients across their membranes.

Acknowledge the longevity of neurons. Neurons can live for the entire lifespan of an organism, which is why they are considered long-lived cells.

Note that neurons generally do not undergo mitosis. Unlike many other cell types, neurons do not divide and replicate, which is why the ability to undergo mitosis is not a characteristic of neurons.
