Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which part of the neuron is a thread-like structure that carries impulses to other neurons?
A
Cell body
B
Dendrites
C
Axon
D
Myelin sheath
Explanation: 

Detailed explanation-1: -Dendrites are thread-like extensions of the cytoplasm of a neuron that receive signals from other neurons. Typically, as in multipolar neurons, dendrites branch into treelike processes, but in unipolar and bipolar neurons, dendrites resemble axons.

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: -Axons pass the nerve impulses on to other cells. A single neuron may have thousands of dendrites, so it can communicate with thousands of other cells but only one axon.
