highlight any three features of neuron that influence the velocity of nerve impuse
Answers
Answer:
Temperature - The higher the temperature, the faster the speed. ...
Axon diameter - The larger the diameter, the faster the speed. ...
Myelin sheath - Only vertebrates have a myelin sheath surrounding their neurones.
Answer:
Neurones send messages electrochemically; this means that chemicals (ions) cause an electrical impulse. Neurones 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, so to understand the nerve impulse we need to revise some properties of cell membranes.
The speed is affected by 3 factors:
Temperature - The higher the temperature, the faster the speed. ...
Axon diameter - The larger the diameter, the faster the speed. ...
Myelin sheath - Only vertebrates have a myelin sheath surrounding their neurones.
