Correct Answer is B
Explanation
a. Cell body: The cell body is the main part of the neuron containing the nucleus and other organelles. It does not directly transmit impulses.
b. Axon: The axon is a long fiber that carries electrical impulses away from the cell body towards other neurons or muscles.
c. Synapse: A synapse is a junction between two neurons where nerve impulses are transmitted. The axon of one neuron transmits an electrical signal to the dendrite or cell body of another neuron across a small gap. Neurotransmitters are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron, either exciting or inhibiting it.
d. Dendrite: Dendrites are short, branching fibers that receive signals from other neurons and transmit them towards the cell body.
