Concept:Nerve impulses travel in a fixed direction within a neuron, moving towards the cell body through sensory fibres and away from it through motor fibres.
Explanation:Dendrons are the branching nerve fibres that receive signals from other neurons or receptors.
They conduct these impulses towards the nerve cell body.
Axons, by contrast, carry impulses away from the cell body towards other neurons or effectors.
The myelin sheath is an insulating layer around the axon and does not conduct impulses towards the cell body.
Synaptic nodes are junctions where impulses pass between neurons, not the actual pathway to the cell body.
So, the fibres that bring impulses towards the nerve cell are the dendrons.
Answer:B. dendrons
