Question : Nerve fibres transmit the nerve message by _____means.

Answer»

chemical
physical
electrochemical
ELECTRICAL

Solution :Due to a gap of 200Å in between two NEURONS, the electrical transmission of nerve impulse is not possible because the post-synaptic membrane cannot be depolarised WITHOUT the aid of NEUROTRANSMITTERS (chemicals).Hence, in this way, the transmission of nerve impulse is an electrochemical INCIDENCE.
