Biology: Nerve Impulse

Question 1

how does an impulse move

Answer 1

moves down myelinated axon

jumps from node to node

Question 2

what happens when it jumps from node to node

Answer 2

increase of speed

Question 3

synapse

Answer 3

point of contact at which impulses are passed from one cell to another
small gap between the axon and neuron and dendrites

Question 4

neurotransmitters

Answer 4

tiny vesicles or sacs filled with chemicals at the axon terminal at a synapse
used by one neuron to signal another

Question 5

what happens when an impulse reaches the axon terminal

Answer 5

vesicles release neurotransmitters into the synapse

Question 6

what happens with the molecules of the neurotransmitter after

Answer 6

diffuse across gap and attack to special receptors on the membrane of the neuron receiving the impulse

Question 7

what happens when enough neurotransmitters attach to the cell membrane

Answer 7

it stimulates it to continue the impulse
