WitrynaAn electrical nerve impulse travels along the axon of the first neuron (presynaptic neuron). When the nerve impulse reaches the dendrites at the end of the axon, chemical messengers called... WitrynaState the direction followed by a nerve impulse while travelling in the body of an organism. Answers (1) Nerve Impulse - A nerve impulse can be described as the electrical signal that transmitted along with a nerve fibre. The electrical impulse travels from dendrite to the cell body and then along the axon.

WitrynaHyperpolarization and depolarization. At rest, a typical neuron has a resting potential (potential across the membrane) of -60 −60 to -70 −70 millivolts. This means that the interior of the cell is negatively charged relative to the outside.
