<span>A neuron, or a nerve cell, is an excitable cell constituting the basic functional unit of the nervous system. Neurons provide the transmission of nerve impulses which are electric signals.
The neurons have the same composition as any other body cell, except some differentiations proper to the neurone, and the fact that the neurone never do mitose (cell division)
A neuron's nucleus is located in its Cell body (soma, cytoplasm are also correct answers). axon myelin sheath dendrite synaptic terminals
Axon is a very long extension of the cytoplasm which goes through a specific destination (for example the brain if it is a sensory receptor).
Myelin sheath covers some axons to provide a protection and increase the speed of the nerve impulses.
Dendrite is small extensions of cytoplasm, their role is to receive nerve impulses from other neurons.
Synaptic terminals are located at the end of the axon, it is responsible for transmitting the impulse to another neuron by a chemical way instead of the electric one.</span>
The correct answer is that a neuron's nucleus is located in its cell body also known as the soma. The cell body of a neuron is not indifferent with cell bodies of other cells of the body, it also contains organelles such as the mitochondria and endoplasmic reticulum. The cell body also houses the neuron's nucleus which is where the genetic material of the cell is stored.
<em>The axon is a part of a neuron that propels the signals away from the cell body. The dendrites are parts of a neuron that receives signals from another neuron and propels the signal towards the cell body. Synaptic terminals are structures where the axon of a presynaptic neuron meet the dendrites of a postsynaptic neuron.</em>
