An axon has four terminal ends connected with dendrites of four different neurons. Its nerve impulse will.
1 become weak due to distribution into four.
2 travel in all the four neurons with equal strength.
3 pass on to one neuron only.
4 travel to none because the movement of impulse is from dendrite to axon.
Explanation:
(b) An axon has four terminals ends connected with dendrites of four different neurons. Its nerve impulse will travel in all the four neurons with equal strength.

Which of the following is the correct direction of travel for a nervous impulse?
1 Dendrite, nerve cell body, axon
2 Axon, nerve cell body, dendrite
3 Nerve cell body, axon, dendrite
4 Dendrite, axon, nerve cell body
Explanation:
(a) Dendrites collect impulses and carry them toward the nerve cell bodies. Axons then pick up the integrity of the signal and speeds transmission along the axon.

2 positively charged on both-outside and inside.
3 negatively charged outside and positively charged inside.
4 negatively charged on both-outside and inside.
Explanation:
(a) During recovery, a nervefibre becomes positively charged outside and negatively charged inside.
