Question
Chapter 48.1, Problem 1CC
Summary Introduction
To explain: The difference in structures and functions of axon and dendrites.
Concept introduction:
Neurons are the nerve cells that transfer information within the body. A neuron is made up of dendrites and an axon. Communication by the neurons is sent as electrical signals for long distances and chemical signals for short distances.
