Explanation:
Detailed explanation-1: -The axon is a single protoplasmic fiber that extends from the cell body. It is the longest part of the neuron which conducts impulses away from the cell body.
Detailed explanation-2: -Dendrites. Dendrites and axons are cytoplasmic extensions, or processes, that project from the cell body. They are sometimes referred to as fibers. Dendrites are usually, but not always, short and branching, which increases their surface area to receive signals from other neurons.
Detailed explanation-3: -Axon – The long, thin structure in which action potentials are generated; the transmitting part of the neuron. After initiation, action potentials travel down axons to cause release of neurotransmitter.
