Question

The junction between two neurons is called a:

• A. Synapse
• B. Axon
• C. Dendrites
• D. None of the above

Answer 1

The correct option is A

Synapse

The correct option is option A.

Explanation of the correct option:

1. It is the junction between two neurons.
2. It is the point from where impulse passes from one neuron to the other.
3. In the synapse, the cell which transmits impulses is called the presynaptic cell and the cell which receives impulses is called the postsynaptic cell.
4. A narrow gap called the synaptic cleft exists which separates the presynaptic cleft from the postsynaptic cleft.
5. The gap is filled with synaptic fluid.

Explanation of the incorrect options:

Option B:

1. The longest part of the neuron is called an axon.
2. It is of uniform thickness.
3. It transmits nerve impulses away from the cell body to the dendrites.

Option C:

1. It is a part of the neuron that has thin and short fibers which branch repeatedly and project out from the cell body.
2. They help in the conduction of nerve impulses from the synapses towards the cell body.

Final answer: The junction between two neurons is called a synapse.
