Final answer:
Neurons are the cells responsible for communicating electrical signals within the nervous system. Their structure and shape allow for the complex connections in the nervous system.
Step-by-step explanation:
Neurons are the cells considered to be the basis of nervous tissue. They are responsible for the electrical signals that communicate information about sensations, and that produce movements in response to those stimuli, along with inducing thought processes within the brain.
An important part of the function of neurons is in their structure, or shape. The three-dimensional shape of these cells makes the immense numbers of connections within the nervous system possible.
