Answer 1

Dendrite is the extension of a neuron in a branched form. Most neurons have multiple dendrites, which are typically short and branches, and these dendrites are specialized synaptic contacts with terminals of other nerve cells to transmit nerve impulses. The connection between nerve cells and brain helps in allowing the memory to extract and store information. An axon is in the body part of a nerve cell, which extends axis-shaped or thread. The axon is covered with a layer of myelin, and its function is to transport the signals. From the far end of the axon, nerve impulses are transmitted to other neurons or target organs. Neuron is the most common word which is used when referring to the brain and it is a cell whose role is the transmission of electrical signals.
