An extension of a neuron that carries impulses away from the cell body
A
Dendrite
B
Nerve
C
Vein
D
Axon
Explanation: 

Detailed explanation-1: -They are called afferent processes because they transmit impulses to the neuron cell body. There is only one axon that projects from each cell body. It is usually elongated and because it carries impulses away from the cell body, it is called an efferent process.

Detailed explanation-2: -axon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells. Some axons may be quite long, reaching, for example, from the spinal cord down to a toe.

Detailed explanation-3: -An extension or process called an axon carries impulses away from the cell body. Nervous tissue also includes cells that do not transmit impulses, but instead support the activities of the neurons.

Detailed explanation-4: -The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS.
