The transmission of impulses along a nerve fibre is characterized by
- hormonal and temperature changes
-
electrical and ionic changes
- hormonal and changes
- electrostatic changes
The correct answer is: B
Explanation
Neurons send messages electrochemically; this means that chemicals (ions) cause an electrical impulse. Neurons and muscle cells are electrically excitable cells, which means that they can transmit electrical nerve impulses. These impulses are due to events in the cell membrane.
