Final answer:
Neurons have dendrites that grow out to network and share information, establishing processes for new thought patterns.
Step-by-step explanation:
Neurons have extensions that allow them to network and share information, contributing to the development of new thought processes. The correct answer to the question is dendrites, which are the branching structures that grow out from the neuron's cell body (soma). These dendrites receive information from other neurons at areas called synapses. In contrast, each neuron typically has a single axon that sends information away from the neuron's cell body to other cells. This structural arrangement means that information in a neuron flows from dendrites, across the cell body, and down the axon in one direction, giving the neuron polarity.
