dendrites
An axon is the extension of a neuron and it sends nerve impulses away from the cell. In simpler words it is the "tail" of a nerve cell which sends messages to other cells.
The end of one neuron, the presynaptic button, sends messages to other cells by releasing neurotransmitters (chemical messengers) into the synaptic cleft (a small space between two neurons). The other cell, whether it be a neuron, a muscle, a sweat gland, etc., will receive this message at the post synaptic membrane of its cell, and will respond accordingly.
The functional and structural unit of the nervous system for fast communication are called neurons. A neuron is made of cell body with extensions which are the axons and dendrites that carry impulses.
Afferent neurons carry information to the CNS, and efferent neuron carries it away.
Fibres which carry impulses towards the cell body of a neuron are called dendrites. The axon is the fibre which carries impulses away from the cell body of a neuron.
The axons.

Axon.
Remember: Axons away, so dendrites carry messages from the cell, and axons carry them away.

Efferent neuron
it helps to speed up the process of transmitting messages between neurons.
