Question: Extract the answer to the question from the following context. Question: Through what organic material do neurons signal each other? Context: The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. Only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain; diffuse or localised nerve nets are present instead. The brain is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell. The brain is the most complex organ in a vertebrate's body. In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.
Answer: axons

Question: Extract the answer to the question from the following context. Question: What is not up for discussion? Context: Doctrines of Jehovah's Witnesses are established by the Governing Body. The religion does not tolerate dissent over doctrines and practices; members who openly disagree with the religion's teachings are expelled and shunned. Witness publications strongly discourage followers from questioning doctrine and counsel received from the Governing Body, reasoning that it is to be trusted as part of "God's organization". It also warns members to "avoid independent thinking", claiming such thinking "was introduced by Satan the Devil" and would "cause division". Those who openly disagree with official teachings are condemned as "apostates" who are "mentally diseased".

doctrines and practices
