Question

Nerve fibres conduct impulses in

• A. One direction
• B. Two direction
• C. Multidirection
• D. None of the above

Answer 1

The correct option is A One direction

Neurons or nerve cells generate impulses (chemical or electrical), that travel as waves of depolarization along the cell's membrane. Every neuron has a nerve cell body and dendrites, axons that propagate these impulses. Signal transmission is always unidirectional i.e., moving towards the nerve cell body along a dendrite or away from the nerve cell body along an axon. The impulse never changes its direction.
Thus, the correct answer is the option (A), 'One direction'.
