Jack suffered a brain injury as a result of hitting his head while waterskiing. One of the problems that developed was that Jack could not pronounce certain words correctly for a long period of time until he had extensive speech therapy and can now speak as he did before his accident. This is an example of the brain's __________ which allowed the structure and function of his brain cells to change to adjust to the trauma.

What is a neuron? Describe the three parts of a neuron and their functions. Explain the process of how a neural message is transmitted from the end of one neuron to the beginning of another and the process by which a neuron moves from a resting state (resting potential) to firing (action potential) and then back to a resting state.

During a resting potential, the neuron is positively charged inside and negatively charged outside.
