Explanation:
Detailed explanation-1: -A unipolar neuron has one axon which extends into dendrites, though this splits into two parts in pseudounipolar neurons.
Detailed explanation-2: -Schwann cells myelinate the single process extending from the cell body, as well as the two processes produced by the splitting of that single process (one of which will have axon terminals at its end, and the other of which will have dendrites at its end.
Detailed explanation-3: -Sensory neurons A chemical input comes from taste or smell, which neurons then send to the brain. Most sensory neurons are pseudounipolar, which means they only have one axon which is split into two branches.
