Cellular Communication

3. Principal inhibitory CNS transmitter opens Cl or K channels. Geee!, I love that four piece swedish pop group.
6. Modulatory neurotransmitter important in mood and sleep. Doomscrolling is anti this
7. The conduction process where electrical signals, or action potentials, "jump" from one node of Ranvier to the next along a myelinated axon.
10. Encloses bundles of axons called fascicles. They do a peri good job.
12. Some could say, I'm the oligodendrocytes of the peripheral nervous system. Also, Billy Madison hates this 'animal' cell
14. Main excitatory neurotransmitter in the brain. Good to have a mate like this.
15. Group of axons bundled within perineurium functional unit inside a peripheral nerve
17. Return toward resting potential due to K efflux through voltage gated potassium channels
18. A form of chemical signalling where the cell targets a distant cell through the bloodstream.
19. A fatty insulating sheath around many axons, made by Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS).

1. They act as messengers that carry information from the presynaptic NEUROns to the postsynaptic target.
2. Gaps in myelin where ion channels are concentrated. Sounds kinda French
4. All or none electrical signal propagated along an axon via voltage gated channels. Live to your full ...
5. Modulatory neurotransmitter important in movement and reward. Kinda dope.
8. Upstroke of the action potential due to Na influx through voltage gated sodium channels.
9. Neurotransmitter at neuromuscular junction and in autonomic nervous system. You will ACE this one!
11. Proteins on the postsynaptic membrane that bind neurotransmitters.
13. Cells in the nervous system (neurons and glia) communicate in two main ways: Electrical Communication and .... Communication
16. Long process of a neuron that carries electrical signals away from the cell body. When Harry was a teenager, he put this deodorant '... on'
