Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which part of the neuron is a long fiber that extends from the cell body to the axon terminals; the impulse travels down this like a superhighway.
A
dendrite
B
terminal gap
C
cell body terminal
D
axon
Explanation: 

Detailed explanation-1: -The axon is a single protoplasmic fiber that extends from the cell body. It is the longest part of the neuron which conducts impulses away from the cell body.

Detailed explanation-2: -The long fibre arising from the cell body of the neuron is called an axon.

Detailed explanation-3: -Dendrites. Dendrites and axons are cytoplasmic extensions, or processes, that project from the cell body. They are sometimes referred to as fibers. Dendrites are usually, but not always, short and branching, which increases their surface area to receive signals from other neurons.

Detailed explanation-4: -Axon. The axon is the elongated fiber that extends from the cell body to the terminal endings and transmits the neural signal.
