Question

Which part of a neuron conducts impulses away from the cell body toward the target cell(s)?

1) axon hillock
2) cell body
3) dendrites
4) axon
5) terminal knob

Answer 1

The axon is the part of the neuron that conducts impulses away from the cell body towards other cells, making the correct option 4) axon.

Step-by-step explanation:

The part of a neuron that conducts impulses away from the cell body toward the target cell(s) is the axon. The axon is a long, thin projection of a neuron that is responsible for transmitting nerve impulses to other cells. At the end of the axon are axon terminals where synapses with other cells occur. Myelin sheaths often cover the axon to enhance the speed of electrical signal transmission. An axon may branch out numerous times, serving as the primary conduit for signals within the nervous system.

To clarify from the provided options, the correct option for the part of the neuron that transmits impulses away from the cell body is: 4) axon. This is because the axon hillock is where the axon starts, the cell body, or soma, contains the nucleus and organelles, the dendrites receive electrical signals, and the terminal knob, or axon terminal, is where the neuron communicates with other cells or the synapse.
