Q

why does the nerve impulse travel along the axon

A

so the impulse can be sent to other neurons

16
Q

Nodes of Ranvier are gaps in between which stricture

A

the Myelin Sheath

17
Q

what do Nodes of Ranvier force the impulse to do

A

“jump” across the gaps

18
Q

what impact on transmission do nodes of ranvier have

A

they speed up transmission

19
Q

how do nodes of ranvier speed up transmission

A

by forcing the impulse to “jump”

20
Q

what is known as the “end” of the Neuron

A

the Transmit Button

21
Q

what is the function of the transmit button

A

to send impulses to other neurons

22
Q

how does the transmit button carry out its function of sending impulses to other neurons

A

by releasing Neurotransmitters

23
Q

the transmit button releases neurotransmitters. into where?

A

the Synaptic gap
